The Soul’s Pilgrimage — Salvation, Warfare, and Perseverance

A. Introduction: The Soul on the Road

The Christian life is a journey. The New Testament writers never let us forget that. Peter calls his readers “pilgrims and sojourners” (1 Pet. 2:11, NKJV). Paul describes himself as running a race, pressing toward the goal (Phil. 3:14). The author of Hebrews pictures the faithful as travelers looking for a city whose builder and maker is God (Heb. 11:10). Everywhere in the apostolic writings, the assumption is that believers are people on the move—not yet home, not yet complete, not yet safe from every danger.

But here is what matters most for our purposes: the New Testament writers consistently describe this pilgrimage in terms that assume the reality of the soul. Salvation is something the soul receives (1 Pet. 1:9). Fleshly desires wage war against the soul (1 Pet. 2:11). Suffering believers are told to commit their souls to a faithful Creator (1 Pet. 4:19). Paul prays that the Lord Jesus Christ be with Timothy’s spirit (2 Tim. 4:22). The church at Philippi is called to stand fast in one spirit, with one mind (Phil. 1:27). And John, writing to his beloved community, assures them that God is greater than their heart—a term that in the New Testament overlaps significantly with soul and spirit as the seat of the inner person (1 John 3:20).1

These are not throwaway phrases. They are not accidental holdovers from a pre-scientific age. They are theologically loaded statements about what salvation does, where spiritual warfare happens, and what part of us God relates to most intimately. And every one of them assumes that the soul—the immaterial inner self—is a real thing. Not a metaphor. Not a figure of speech for the “whole person.” A real, distinguishable dimension of the human person that can be saved, attacked, committed to God’s care, and known by the Almighty.

What makes this chapter especially revealing is the pattern we have seen throughout this book. Of the six passages we will examine here, Edward Fudge discussed only two in The Fire That Consumes—and even those two received a treatment shaped by his physicalist assumptions rather than by careful attention to what the text actually says. The remaining four passages he ignored entirely.2 These are passages where the New Testament writers use the word psyche (soul) or pneuma (spirit) in ways that presuppose the soul’s reality as an entity distinct from the body. A thorough treatment of the biblical data on human nature cannot afford to skip over them.

We will take each passage in turn, working through the Greek, engaging the best scholarship, and asking the same question we have asked throughout this book: Does the text make better sense on a dualist reading or on a physicalist one? The answer, as we shall see, consistently points the same direction.

B. Passage Expositions

1. “Receiving the End of Your Faith—the Salvation of Your Souls” (1 Peter 1:9)

Text (NKJV)

“receiving the end of your faith—the salvation of your souls.”

Exegetical Exposition

The context of this verse is critical. Peter has been writing to scattered, persecuted believers throughout Asia Minor—people he calls “pilgrims of the Dispersion” (1 Pet. 1:1). He opens his letter by celebrating the living hope they have through Christ’s resurrection and the inheritance reserved in heaven for them (1:3–4). Their faith is being tested by various trials, but these trials have a purpose: to prove the genuineness of their faith, which is more precious than gold (1:7). Then comes verse 9, the climax of Peter’s opening thought: the goal—the telos—of their faith is “the salvation of your souls.”3

The Greek phrase is sōtērian psychōn—“salvation of souls.” The word psychē (plural psychōn) is the standard New Testament word for “soul.” It can mean “life,” “self,” or “person” in some contexts—its semantic range is broad.4 But the way Peter uses it here is telling. He does not say “the salvation of your bodies” or even “the salvation of your persons.” He says “the salvation of your souls.” Why?

The physicalist answer is straightforward: psychē here just means “yourselves.” It is a synonym for the personal pronoun. Peter is simply saying, “receiving your salvation.” This is the line Fudge takes. On his reading, psychē in the New Testament almost always means the whole person or the life-force, not an immaterial entity that exists apart from the body.5 There is no dualism here, the physicalist says. Just a normal Greek idiom.

But there are strong reasons to read this differently. First, consider the context. Peter is writing to people whose bodies are suffering. Their physical circumstances are painful. They are experiencing persecution, social rejection, and material loss. Yet Peter tells them that the goal of their faith is the salvation of their souls—not the salvation of their present physical situation. The contrast between bodily suffering and the soul’s salvation only makes sense if the soul is something distinguishable from the body. If psychē just means “yourself,” Peter’s statement would be oddly flat: “You are suffering physically, but the goal of your faith is—your salvation.” That is true but tautological. It lacks the force that the passage clearly intends.6

Second, notice how Peter frames the relationship between present suffering and future hope. The trials test the genuineness of faith (v. 7); the faith is directed toward an inheritance that is “imperishable, undefiled, and unfading, kept in heaven for you” (v. 4); and the ultimate outcome (telos) of that faith is the salvation of the soul. The logic here is eschatological: the body may perish under persecution, but the soul is being saved for something beyond bodily existence. As John Cooper observes, Peter’s language here fits naturally within the broader New Testament pattern of distinguishing what can happen to the body from what God does with the soul.7

Third, the use of psychē in 1 Peter is revealing when taken as a whole. Peter uses the word again in 1:22 (“having purified your souls”), in 2:11 (“fleshly lusts which war against the soul”), in 2:25 (“the Shepherd and Overseer of your souls”), in 3:20 (“eight souls were saved through water”), and in 4:19 (“commit their souls to Him”). In at least two of these cases (2:11 and 4:19), the word cannot be reduced to a simple pronoun without losing the meaning of the sentence. Peter has a developed theological use of psychē that presupposes the soul as a real aspect of the person—the inner self that can be purified, attacked, and entrusted to God.8

The major commentaries confirm this reading. Thomas Schreiner notes that while psychē can function as a synonym for “self,” in 1 Peter 1:9 the term specifically highlights the inner person’s relationship to God’s saving work, distinguishing it from the bodily suffering the recipients are enduring.9 Karen Jobes similarly argues that Peter uses psychē to denote the seat of a person’s spiritual identity—that which relates to God and endures beyond present affliction.10 Wayne Grudem, in his commentary on 1 Peter, connects this verse to the broader biblical pattern of the soul as the immaterial dimension of the person that is the ultimate object of God’s redemptive care.11

What This Means for the Body-Soul Question

If the soul is not a real, distinguishable dimension of the person, then Peter’s language in 1:9 is puzzling. Why specify psychōn rather than just saying “your salvation” or “the salvation of you”? The answer is that Peter wants his persecuted readers to understand something profound: their bodies may be broken, their material circumstances may be dire, but the deepest part of them—the soul, the immaterial self that relates to God—is being saved. The body will be raised later, at the resurrection. But the soul is already secure in Christ’s hands. This is substance dualism in pastoral clothing.

Consider the alternative. On a physicalist reading, the “salvation of your souls” means nothing more than “your salvation.” But then why does Peter even mention the soul? If the whole person is a single, undifferentiated physical entity, the word psychē adds nothing to the sentence. It becomes redundant, like saying “the wetness of the water.” The dualist reading, by contrast, gives the word real work to do. Peter is telling people whose bodies are under attack that the deepest dimension of their personhood—the soul—is being preserved by God’s power. That is a message with teeth. That is a message that can sustain a person through a Roman beating.

Notice too the eschatological framework Peter has set up. The inheritance is “kept in heaven” (1:4). The faith is being tested “by fire” (1:7). And the outcome of that tested faith is the salvation of the soul. Peter is describing a process in which the body endures present suffering while the soul is being brought safely to its eternal destination. The body and the soul are on different timelines, experiencing different things, heading toward different interim destinations. The body may be destroyed by persecution. The soul will be saved. That is not the language of a person who thinks human beings are nothing more than organized matter.63

Fudge’s Treatment

Fudge referenced 1 Peter 1:9 in his broader treatment of the Petrine epistles, but he did not engage the anthropological implications of the verse.12 His treatment focused on the eschatological themes of judgment and destruction in 1 Peter 4:17–18, passing over 1:9 without exploring what “the salvation of your souls” implies about the nature of the soul. This is a recurring pattern: Fudge encounters psychē in the text but does not pause to ask whether the word might be doing something more than acting as a pronoun. His physicalist assumptions guide him past the anthropological data without noticing it.

2. “Fleshly Lusts Which War Against the Soul” (1 Peter 2:11)

Text (NKJV)

“Beloved, I beg you as sojourners and pilgrims, abstain from fleshly lusts which war against the soul.”

Exegetical Exposition

This verse is one of the most anthropologically significant statements in the New Testament, and the fact that Fudge ignored it entirely speaks volumes.

Peter addresses his readers as “sojourners and pilgrims”—the Greek words paroikous and parepidēmous, which describe people who are living temporarily in a foreign land, away from their true home.13 The metaphor is not merely social or political. It is existential. Believers are people whose deepest identity belongs elsewhere. Their bodies walk through this world, but their souls are heading home.

Peter then warns them to “abstain from fleshly lusts which war against the soul.” The Greek is tōn sarkikōn epithymiōn haitines strateuontai kata tēs psychēs. The word strateuontai is a military term—it means to wage war, to campaign against, to conduct a military operation.14 The picture Peter paints is vivid: fleshly desires are an invading army, and the soul is the territory they are attacking.

Now, think about what this means for the body-soul question. Peter sets up a conflict between two things: “fleshly lusts” (sarkikōn epithymiōn) and the “soul” (psychē). The lusts are called sarkikōn—belonging to the sarx, the flesh. The target of their attack is the psychē—the soul. The flesh and the soul are on opposite sides of a battle.

Key Argument: If the soul is just a synonym for “the whole person,” then 1 Peter 2:11 is saying that fleshly lusts wage war against the whole person. But since fleshly lusts come from the person, this would mean the person is waging war against the person. The verse collapses into incoherence. The passage only makes sense if the soul is a genuine dimension of the human person that can be distinguished from the bodily, fleshly desires that assault it.

This is not a subtle point. It is right there on the surface of the text. Peter explicitly contrasts the sarx (flesh) and the psychē (soul). He says one is attacking the other. You cannot reduce the soul to the whole person without destroying the internal logic of the sentence. The very grammar of the verse requires two distinguishable realities within the human being: the flesh that generates sinful desire, and the soul that those desires assault.15

J. P. Moreland makes this observation about passages like 1 Peter 2:11: when the New Testament describes internal spiritual conflict, it consistently frames the conflict in terms of an immaterial self being pulled in different directions by bodily desires on one hand and spiritual aspirations on the other. This pattern makes sense on a dualist anthropology, where the soul is a genuine entity capable of moral agency, and the flesh is a competing set of desires rooted in bodily existence. On a physicalist anthropology, where there is no immaterial soul, the entire framework of spiritual warfare becomes a metaphor for—what, exactly? Brain processes in conflict with other brain processes?16

The connection to the broader Petrine pilgrimage theme is also important. Peter has just called his readers “sojourners and pilgrims.” This is a journey metaphor. The soul is traveling through a hostile land. Fleshly desires are the enemies that line the road, trying to pull the pilgrim off course. The destination is the “salvation of your souls” (1:9). The soul is the pilgrim. The body, with its fleshly appetites, is part of the terrain the pilgrim must navigate. This is profoundly dualist language.17

Commentators across traditions recognize the force of this passage. I. Howard Marshall observes that Peter’s flesh-versus-soul contrast draws on a longstanding Jewish and early Christian tradition that distinguished the inner self from the desires of the body.18 This is not Platonism imported into the Bible. It is a biblical anthropology that recognizes what every honest reader of Scripture can see: the human person has an inner life that is distinguishable from, and sometimes in conflict with, the body’s appetites.

We should also notice the verb Peter chooses: strateuontai, “wage war.” This is not mild tension. This is not a gentle tug. This is military conflict. Peter pictures the soul as a fortress and the fleshly desires as an invading army laying siege to its walls. The imagery assumes that the soul has a kind of integrity, a structural reality that can be besieged. You do not wage war against a metaphor. You wage war against something real. Peter’s military language only makes sense if the soul is an actual dimension of the person that has boundaries, that can be defended, and that can be overrun if the pilgrim is not vigilant.

This has profound implications for how we understand sanctification. If the soul is real, then the Christian life involves an actual battle between the desires that arise from our bodily nature and the aspirations of the soul that is being drawn toward God. The soul can win or lose these battles. It can grow stronger in resisting fleshly desires or weaker in giving in to them. This is the framework that underlies the New Testament’s entire ethic of holiness. On a physicalist view, sanctification becomes something far more difficult to describe. If there is no soul, then the “war” Peter describes is simply one set of brain processes competing against another set of brain processes. There is no deeper self being shaped by the conflict. There is no immaterial dimension being purified or corrupted. The biblical picture of spiritual warfare loses its depth and its urgency.

What This Means for the Body-Soul Question

First Peter 2:11 presupposes that the soul is a real target—something that can be attacked, damaged, and defended. The verse makes no sense if the soul is merely a word for the whole person. The flesh-versus-soul contrast is not rhetorical decoration. It is a statement about the structure of human nature. We are beings with a body and a soul, and those two dimensions can pull in different directions. The Christian pilgrim’s task is to protect the soul from the assaults of the flesh, trusting that God will bring the soul safely home.

Fudge’s Treatment

Fudge never addressed 1 Peter 2:11 in The Fire That Consumes.19 He discussed 1 Peter 4:17–18 in connection with the fate of the wicked, and he referenced 1 Peter 1:9 in passing. But this verse—which contains one of the clearest flesh-versus-soul contrasts in the entire New Testament—received no treatment at all. When a passage explicitly pits the flesh against the soul, a book that claims to address what happens to human beings after death ought to reckon with it. The silence is conspicuous.

3. “Commit Their Souls to Him as to a Faithful Creator” (1 Peter 4:19)

Text (NKJV)

“Therefore let those who suffer according to the will of God commit their souls to Him in doing good, as to a faithful Creator.”

Exegetical Exposition

This verse comes at the end of a section about suffering. Peter has been telling his readers not to be surprised by the “fiery trial” they are experiencing (4:12). He has reminded them that judgment begins with the household of God (4:17). And now he gives them a final instruction: those who suffer according to God’s will should “commit their souls to Him.”

The Greek is paratithesthōsan tas psychas autōn—“let them entrust their souls.” The verb paratithēmi means to deposit something with someone for safekeeping, to place something in another’s hands as a trust.20 It is the same word used in banking and legal contexts for entrusting a valuable deposit to a trustworthy guardian. It is also the word Jesus used on the cross: “Father, into Your hands I commit My spirit” (Luke 23:46).21

The parallel to Jesus’ dying words is not accidental. Peter was there when Jesus died—or at least he heard about it from those who were. He would have known that Jesus committed His pneuma (spirit) to the Father at the moment of death, an act that presupposed the spirit’s continued existence after the body died. Now Peter instructs suffering believers to do the same thing with their psychē (soul): deposit it with God for safekeeping.22

Think about what Peter is saying. He is not telling them to commit their bodies to God. He is not telling them to commit their whole selves to God in some vague, general sense. He is specifically telling them to commit their souls to God. Why? Because the body is precisely what is under threat. Persecution targets the body. Imprisonment, beatings, execution—these are things done to the body. Peter’s instruction only makes sense if there is a dimension of the person that is not destroyed when the body is destroyed—and that dimension is the soul, which can be entrusted to God’s faithful care.23

The phrase “as to a faithful Creator” (pistō ktistē) adds another layer. God is the one who created the soul in the first place. He is faithful to preserve what He has made. The soul is a created reality—not self-existent, not inherently immortal, but a genuine creation of God that God will guard and sustain. This is exactly the substance dualist position: the soul is real, created by God, dependent on God for its continued existence, and capable of being entrusted to God’s care even when the body fails.24

Cooper draws attention to the way Peter links the language of soul-committal to the Old Testament tradition found in Psalm 31:5—“Into Your hand I commit my spirit.” David, facing mortal danger, entrusted his spirit to God. Jesus did the same on the cross. Now Peter tells persecuted Christians to follow the same pattern. In every case, the logic is the same: the body may be taken, but the soul (or spirit) can be placed in God’s hands, where it will be safe. This makes no sense on a physicalist anthropology. If the soul is not a real entity that survives death, there is nothing to “commit” to God. The instruction becomes meaningless.25

D. Edmond Hiebert, in his careful commentary on 1 Peter, observes that Peter’s use of psychē here points to “the immaterial part of man which survives physical death and is committed to God’s safekeeping.”26 This is not a controversial reading. It is the most natural one. Peter’s audience was facing the very real possibility that they would be killed for their faith. His instruction to them was not “Don’t worry, God will take care of everything.” It was far more specific: “Deposit your souls with God. He made them. He will keep them safe.”

What This Means for the Body-Soul Question

First Peter 4:19 treats the soul as something real, valuable, and separable from the body’s fate. It is not a metaphor. It is not a pronoun. It is the most precious thing a person has—and it can be placed in the hands of the God who made it. The verse assumes substance dualism. The body may be destroyed by persecutors, but the soul endures in God’s care. This is the same logic we saw in Matthew 10:28: “Do not fear those who kill the body but cannot kill the soul” (as we examined in Chapter 10).

Fudge’s Treatment

Fudge did reference 1 Peter 4:19, but only as part of his broader discussion of the Petrine material on judgment. His treatment focused on the context of 4:17–18—the judgment that begins with the household of God and the fate of the ungodly—without pausing to examine the anthropological significance of Peter’s instruction to “commit their souls” to God.27 Fudge’s attention was, understandably, on the eschatological question: What happens to the wicked? But in rushing past 4:19 to get to 4:17–18, he missed a verse that speaks directly to the nature of the person who faces that judgment. The soul is real enough to be committed to God’s care. That matters.

4. “The Lord Jesus Christ Be with Your Spirit” (2 Timothy 4:22)

Text (NKJV)

“The Lord Jesus Christ be with your spirit. Grace be with you. Amen.”

Exegetical Exposition

This is Paul’s final recorded word to Timothy—perhaps the last sentence Paul ever wrote. He is in prison in Rome, awaiting execution. He knows the end is near: “I am already being poured out as a drink offering, and the time of my departure is at hand” (4:6). He has fought the good fight, finished the race, kept the faith (4:7). And now, in his closing benediction, Paul writes: “The Lord Jesus Christ be with your spirit.”28

The Greek reads ho kyrios Iēsous Christos meta tou pneumatos sou—“the Lord Jesus Christ [be] with your spirit.” The word pneuma (spirit) is used here of Timothy’s human spirit, not of the Holy Spirit. Paul’s prayer is that Christ would be present with Timothy’s innermost self—his spirit, the immaterial core of his personhood.29

Why does Paul say “your spirit” rather than simply “you”? He uses similar language in other benedictions. In Galatians 6:18, he writes: “The grace of our Lord Jesus Christ be with your spirit, brethren.” In Philippians 4:23: “The grace of our Lord Jesus Christ be with your spirit.” In Philemon 25: “The grace of our Lord Jesus Christ be with your spirit.”30 This is a deliberate pattern. Paul does not always close his letters this way—sometimes he says “with you” or “with you all.” But when he chooses to say “with your spirit,” he is making a specific anthropological statement: Christ’s presence is directed to the deepest level of the human person, the spirit.

The physicalist response is predictable: “spirit” here just means “you,” the whole person. It is a figure of speech, synecdoche—the part standing for the whole. And we should acknowledge that synecdoche is a real phenomenon in biblical language. As we noted in Chapter 5, Cooper rightly recognizes that nephesh, ruach, psychē, and pneuma can sometimes function as stand-ins for the whole person.31

But there is a problem with applying the synecdoche explanation too broadly. If pneuma always means “the whole person,” then every time the Bible mentions the spirit, it is simply saying “you.” But this makes the word meaningless. Why would Paul use a specific anthropological term—spirit—when a simple pronoun would do? The answer is that “your spirit” carries a different connotation than “you.” It directs attention to the immaterial, inner dimension of the person. Paul wants Christ to be present not just “with Timothy” in a general way, but specifically with Timothy’s spirit—the place where Timothy knows God, prays, discerns, agonizes, hopes, and worships.32

This is especially poignant given the context. Paul is about to die. He is writing to Timothy from death row. His body is about to be destroyed by the executioner. But Paul’s final prayer is not about Timothy’s body or even his external circumstances. It is about his spirit. Paul wants the Lord to be present at the deepest level of Timothy’s inner life. The focus on the spirit rather than the body is itself a quiet testimony to Paul’s anthropology: the spirit is where Christ meets us, and it is the spirit that matters most when everything else is being stripped away.33

Gordon Fee, who is not a strong substance dualist, nonetheless acknowledges that Paul’s use of pneuma in benedictions like this one points to “the human spirit as the place of divine-human encounter.”34 Even scholars cautious about drawing ontological conclusions from Paul’s language recognize that the spirit, for Paul, is not a throwaway term. It identifies the dimension of the person that interfaces with God.

There is something deeply moving about the personal setting of this benediction. Paul is chained. He has been deserted by many of his coworkers. Demas has abandoned him “having loved this present world” (4:10). Only Luke is with him (4:11). Winter is coming, and Paul asks Timothy to bring his cloak (4:13). The physical conditions are miserable. Paul’s body is aging, confined, cold, and soon to be executed. And yet his final written prayer is not about bodies or comfort or survival. It is about the spirit. “The Lord Jesus Christ be with your spirit.” At the end of everything, when the body has nothing left to give, the spirit is what remains. The spirit is what matters. The spirit is where Christ is most present.

This is not an accident of language. This is a dying apostle’s deliberate theological statement about what a human being is. Paul, facing the executioner, does not pray for Timothy’s health or safety. He prays for Timothy’s spirit. That tells us where Paul thinks the real action is. The spirit is the core of the person. The body is the temporary dwelling. And when the dwelling is about to be dismantled—as Paul’s own body was about to be dismantled—it is the spirit that goes on, the spirit that Christ accompanies, the spirit that is the irreducible “you.”

What This Means for the Body-Soul Question

Paul’s closing benediction in 2 Timothy 4:22 assumes that the human spirit is a real, distinguishable dimension of the person. It is the place where Christ’s presence is experienced most directly. This fits seamlessly with a dualist anthropology: the spirit is the immaterial core of the person, the seat of consciousness, moral agency, and relationship with God. On a physicalist view, the spirit is just a word for the person. But Paul already has a word for the person—“you.” He chose “your spirit” instead, and that choice is significant.

Fudge’s Treatment

Fudge did not address 2 Timothy 4:22 in The Fire That Consumes.35 This is not surprising, since the verse does not deal directly with the fate of the wicked. But it is an anthropological text—one that reveals how Paul thinks about the structure of the human person. A comprehensive study of what Scripture teaches about human nature would need to account for this verse and the pattern of Pauline benedictions it represents. Fudge’s focus on final punishment left these anthropological data unexamined.

5. “Stand Fast in One Spirit, with One Mind” (Philippians 1:27)

Text (NKJV)

“Only let your conduct be worthy of the gospel of Christ, so that whether I come and see you or am absent, I may hear of your affairs, that you stand fast in one spirit, with one mind striving together for the faith of the gospel.”

Exegetical Exposition

Paul’s letter to Philippi is deeply personal. He writes from prison, facing the very real possibility of execution. Just a few verses earlier, he expressed his famous dilemma: “To live is Christ, and to die is gain” (1:21). He wants to depart and be with Christ but recognizes that staying alive serves the church (1:23–24). Now he turns his attention to the Philippians’ corporate life and calls them to unity.

The Greek phrase is stēkete en heni pneumati, mia psychē synathlounte—literally, “stand firm in one spirit, with one soul striving together.” Paul uses both pneuma (spirit) and psychē (soul) in the same sentence.36 The NKJV translates psychē here as “mind,” which is an interpretive choice. Other translations render it “soul” (ESV note) or “heart and mind” (NIV). The point is that Paul calls the Philippians to unified inner life—one spirit, one soul—not merely unified behavior or external agreement.37

Some scholars argue that pneuma here might refer to the Holy Spirit rather than the human spirit. This is possible—“stand firm in one Spirit” could mean standing firm in the one Holy Spirit who unites the church.38 But even on that reading, the following phrase—mia psychē, “with one soul”—is undeniably anthropological. Paul is calling for unity at the level of the soul. The Philippians are to strive together with a single psychē, a united inner disposition. The soul here is the seat of will, commitment, and passion.39

What is interesting for our purposes is the way Paul distinguishes different dimensions of the person. Even if we take pneuma as the Holy Spirit, the pairing with psychē shows that Paul thinks of the inner life of the person in layered terms. There is a spiritual dimension (whether the Holy Spirit’s work or the human spirit) and a soulish dimension (the psychē—the seat of desire, will, and intention). Paul does not flatten these into one undifferentiated whole. He distinguishes them.40

If pneuma here does refer to the human spirit—which is a live and well-defended option—then the verse is even more striking. Paul would be saying: “Stand firm in one spirit, with one soul striving together.” Spirit and soul are paired as two dimensions of the immaterial inner life. This echoes the pattern we saw in 1 Thessalonians 5:23, where Paul distinguishes “spirit, soul, and body” (treated in Chapter 15). Whether Paul is a strict trichotomist or simply uses different terms for overlapping aspects of the immaterial self, the point is clear: he thinks of the human person as having inner dimensions that are not reducible to the body.41

Moisés Silva, in his commentary on Philippians, notes that the pairing of pneuma and psychē here reflects Paul’s characteristic way of speaking about the whole inner person. The terms are not identical in meaning but overlap significantly, both pointing to the non-physical core of human experience and agency.42

What This Means for the Body-Soul Question

Philippians 1:27 shows that Paul conceives of the inner life as a real, structured reality—not merely a byproduct of brain activity or a figure of speech for the whole person. The church is called to be united at the level of spirit and soul. These are the dimensions where commitment, passion, and loyalty reside. On a dualist anthropology, this makes perfect sense: the spirit and soul are immaterial realities that can be united by the Holy Spirit’s work. On a physicalist anthropology, the verse reduces to a call for behavioral agreement, which strips it of its depth.

Fudge’s Treatment

Fudge did not address Philippians 1:27 in The Fire That Consumes.43 This is understandable, since the verse is not about final punishment. But the verse is about what a human being is. And any anthropology that claims to be biblical needs to account for the way Paul talks about the inner person.

6. “God Is Greater Than Our Heart” (1 John 3:20)

Text (NKJV)

“For if our heart condemns us, God is greater than our heart, and knows all things.”

Exegetical Exposition

First John 3:20 may seem like an unusual passage to include in a chapter about the soul, since it uses the word “heart” (kardia) rather than “soul” or “spirit.” But this is precisely why it matters. In the New Testament, the “heart” functions as a near-synonym for the inner self, overlapping significantly with psychē and pneuma.44 The heart is the place of intention, conviction, conscience, and moral awareness. By including this verse, we can see how the broader anthropological vocabulary of the New Testament consistently points to a real, interior dimension of the person that is distinguishable from the body.

John’s context is deeply pastoral. He has been urging his readers to love not merely in word but in deed and truth (3:18). He then acknowledges a common spiritual experience: sometimes our conscience accuses us. Our heart condemns us, telling us we have failed, that we are not good enough, that our love is inadequate. John’s response is stunning in its simplicity and comfort: God is greater than our heart, and He knows all things.45

The Greek phrase ho theos meizōn estin tēs kardias hēmōn—“God is greater than our heart”—establishes a direct relationship between God and the inner self. The heart is not the physical organ pumping blood. It is the moral and spiritual center of the person, the place where conscience operates, where guilt is felt, and where assurance is received. John’s point is that God has direct access to this inner dimension and has authority over it. When the heart condemns, God can overrule the condemnation because He sees the full picture.46

What makes this verse significant for the body-soul question is the implied ontology. John treats the heart as a genuine aspect of the person that can independently “condemn”—that is, pass moral judgment on the self. God, in turn, relates to this inner dimension directly: He is “greater than our heart.” The verse assumes a layered anthropology in which the inner self has its own operations (accusing, judging, deliberating) and God interacts with it as a real entity. This is not the language of a flatly physicalist world where the heart is just a metaphor for neural states.47

Throughout the Johannine writings, the interior life of the believer is given enormous weight. John speaks of the Father and Son making their home “in” the believer (John 14:23), of the Spirit dwelling “in you” (John 14:17), and of Christ abiding “in us” (1 John 3:24). This indwelling language assumes a genuine interior space—a spiritual dimension of the person that can be inhabited by God’s presence. The heart in 1 John 3:20 is part of this same inner landscape. It is the seat of moral self-awareness, the place where the believer encounters God’s judgment and God’s grace at the deepest level.48

Moreland and Rae, in Body & Soul, argue that the Bible’s consistent use of “heart” language to describe moral and spiritual operations is itself evidence for substance dualism. The heart, soul, and spirit in Scripture are not synonyms for the brain. They describe a dimension of the person that thinks, wills, desires, and responds to God in ways that transcend mere physical processes. When John says “God is greater than our heart,” he is affirming that God has sovereign authority over the immaterial inner self, not merely over a collection of neurons.49

There is one more thing worth noting. John says that God “knows all things.” This is a statement about divine omniscience, but it is also a statement about the soul’s transparency before God. God sees what the heart sees—and more. God knows the motives behind our actions, the fears behind our guilt, the love behind our failures. This kind of divine knowledge presupposes that the inner life is a real domain, not a fictional one. God knows things about our hearts that even we do not know about ourselves (compare Jeremiah 17:9–10: “The heart is deceitful above all things … I, the LORD, search the heart”). This level of divine intimacy—God knowing the hidden operations of the heart—only makes sense if the heart (the inner self, the soul) is a genuine reality that God can access and examine. On a physicalist account, what would it mean for God to “search the heart”? To scan neural pathways? To analyze biochemical processes? The language is stretched to the breaking point.

The church father Augustine captured this beautifully when he reflected on the relationship between God and the soul. In his Confessions, Augustine wrote to God: “You were more inward to me than my most inward part.” Augustine understood that God’s relationship to the human soul was not external—not a matter of observing behavior from the outside—but internal, intimate, and direct. God dwells in the soul and knows the soul from within. That is the same picture John gives us in 1 John 3:20. God is greater than our heart because God inhabits the territory of the heart. He does not merely monitor it from a distance.62

What This Means for the Body-Soul Question

First John 3:20 adds the “heart” to our growing list of New Testament terms for the inner self. Along with psychē (soul) and pneuma (spirit), kardia (heart) functions as a designation for the immaterial dimension of the person. John treats the heart as a moral agent with its own operations—it can condemn. And he affirms that God relates to this inner agent directly. The cumulative effect is unmistakable: the New Testament writers conceive of the human person as having a genuine interior life that is not reducible to the body. Whether they call it soul, spirit, or heart, they are referring to the same basic reality—the immaterial self that knows God, responds to God, and is known by God.

Fudge’s Treatment

Fudge did not address 1 John 3:20 in The Fire That Consumes.50 This is to be expected, since the verse is not about final punishment. But the verse is anthropologically rich. It tells us something important about how the New Testament writers understood the inner life of the human person. A physicalist anthropology that reduces heart, soul, and spirit to “the whole person” cannot do justice to the way these terms actually function in the text.

C. Synthesis: The Soul as Pilgrim, Warrior, and Deposit

Step back for a moment and look at what we have found. Six passages. Three from Peter, one from Paul to Timothy, one from Paul to the Philippians, and one from John. Spanning different authors, different audiences, different literary genres, and different decades of the first century. And yet they all do the same thing: they treat the soul (or spirit, or heart) as a real, distinguishable dimension of the human person that plays a central role in the Christian life.

In 1 Peter 1:9, the soul is the object of salvation—the thing being saved. In 1 Peter 2:11, the soul is the target of spiritual warfare—the thing being attacked. In 1 Peter 4:19, the soul is the deposit—the thing entrusted to God’s care. In 2 Timothy 4:22, the spirit is the meeting place—where Christ’s presence is experienced most intimately. In Philippians 1:27, spirit and soul are the basis of unity—the dimensions where the church must be one. And in 1 John 3:20, the heart is the moral judge—the place where conscience operates and God overrules.51

Each of these roles presupposes that the soul is real. Not a metaphor. Not a synonym for “the whole person.” A genuine, functioning dimension of human nature that can be saved, attacked, entrusted, indwelt, unified, and judged. The physicalist reduction of psychē and pneuma to “person” or “life-force” cannot account for this range of usage. When Peter says fleshly lusts “war against the soul,” he is not saying that the person wars against the person. When Paul says “the Lord be with your spirit,” he is not simply saying “the Lord be with you.” The specific anthropological terms are doing real work in these sentences, and that work only makes sense on a dualist reading.

Cooper makes a crucial observation that applies perfectly to this chapter’s passages: even if individual terms like psychē and pneuma are semantically flexible, the patterns of usage across the New Testament consistently point to a genuine immaterial dimension of the person. The dualist does not need every occurrence of psychē to mean “immaterial soul” in order to make the case. What matters is the cumulative picture—and the cumulative picture is overwhelmingly dualist.52

Rickabaugh and Moreland make a complementary point. They argue that the best explanation for the diverse functions attributed to the soul, spirit, and heart in Scripture is that these terms refer to an ontologically real immaterial substance. No physicalist account—whether nonreductive physicalism, constitution theory, or property dualism—can adequately explain why the New Testament writers consistently treat the inner self as a genuine entity that can exist, act, and be acted upon independently of the body’s condition. The simplest and most natural explanation is that the apostles believed what the church has always believed: the soul is real.53

Insight: Peter, Paul, and John all write as if the soul is a genuine entity—something that can be saved, attacked, committed to God’s care, and indwelt by Christ. The physicalist must argue that all three apostles were merely using figures of speech. The dualist argues that they meant what they said. The burden of proof lies with those who claim the apostles didn’t mean it.

The strongest physicalist counter-argument is the synecdoche objection: these are all figures of speech, parts standing for the whole. And yes, synecdoche is real. But as Cooper warns, synecdoche can be invoked too easily. When every occurrence of psychē, pneuma, and kardia is dismissed as “just a figure of speech,” the interpreter has effectively decided in advance that the text cannot teach dualism, no matter what it says. That is not exegesis. That is a philosophical commitment masquerading as a linguistic observation.54

What we need is a principled method for distinguishing genuine synecdoche from ontological statement. And the passages in this chapter provide clear criteria. In 1 Peter 2:11, the soul and the flesh are set in opposition—you cannot reduce one to the other without collapsing the contrast. In 1 Peter 4:19, the soul is committed to God as a deposit while the body faces destruction—the two are heading in different directions. In 2 Timothy 4:22, Paul specifies “your spirit” rather than “you”—an unnecessary distinction if the spirit is just a synonym for the person. These are not cases of synecdoche. They are cases where the anthropological terms are doing real, irreducible work.

Common Objection: “The New Testament writers were not doing philosophy. They were not trying to build an anthropological system. We should not read ontological claims into pastoral and practical texts.” This objection has a grain of truth: Peter and Paul were not writing dissertations on the mind-body problem. But it misses the point. You do not have to be doing philosophy to reveal your ontological assumptions. When Peter says fleshly lusts “war against the soul,” he is not writing a treatise on substance dualism. He is giving pastoral advice. But the advice assumes something about what a human being is—namely, that the soul is a real dimension of the person that can be attacked by desires rooted in the flesh. His practical instruction depends on an ontological assumption. Strip away the assumption, and the instruction collapses.

A second objection deserves attention. Some physicalists argue that even if the biblical writers used dualist-sounding language, they were simply accommodating the pre-scientific worldview of their audiences. The writers did not actually believe in an immaterial soul; they were using the only conceptual vocabulary available to them. This objection is deeply problematic for anyone who holds a high view of Scripture. If the Holy Spirit inspired these writers to communicate God’s truth, then the anthropological framework embedded in their writings is not accidental. It is part of what God intended to teach. To say that Peter and Paul were merely “accommodating” their culture’s belief in the soul is to say that the Spirit allowed misleading anthropological assumptions to pervade the apostolic writings without correction. That is a heavy price to pay for maintaining physicalism.60

A third common response is to argue that the real test of any anthropology is not how the soul-language functions in individual verses but whether the Bible as a whole supports the idea of a disembodied existence. Physicalists often claim that the Bible’s emphasis on bodily resurrection shows that God’s ultimate plan is for embodied persons, not disembodied souls. This is absolutely right—as far as it goes. No substance dualist denies the importance of the resurrection body. The question is not whether the body matters (it does!) but whether the soul exists as a genuine entity between death and resurrection. The passages in this chapter, taken together with the intermediate state texts treated in Chapters 13 and 14, show that it does. The soul is real. The body is coming back. Both are true. They are not in competition.61

D. Cross-References and Connections

The passages examined in this chapter connect powerfully to the broader argument of this book at several key points.

First, the “salvation of your souls” in 1 Peter 1:9 echoes Jesus’ teaching in Mark 8:36–37: “What will it profit a man if he gains the whole world and loses his own soul?” (treated in Chapter 9). In both cases, the soul is the ultimate object of value—something that can be lost or saved, and whose fate is distinct from the body’s material condition. Jesus and Peter are working with the same anthropology: the soul is the most important thing about a person, and its salvation is the deepest purpose of faith.55

Second, Peter’s instruction to “commit their souls to Him” in 1 Peter 4:19 directly parallels the soul-departure narratives we examined in Chapters 6 and 12. David prayed “Into Your hand I commit my spirit” (Ps. 31:5), Jesus said the same on the cross (Luke 23:46), and Stephen echoed it at his martyrdom (Acts 7:59). This is a tradition: when the body is about to die, the soul or spirit is entrusted to God. The tradition only makes sense if there is a soul or spirit that survives the body’s death.

Third, the flesh-versus-soul conflict in 1 Peter 2:11 connects to Jesus’ statement in Matthew 10:28: “Do not fear those who kill the body but cannot kill the soul” (treated in Chapter 10). In both passages, the soul is set apart from the body’s physical fate. What threatens the body does not necessarily threaten the soul. And what harms the soul (fleshly lusts, in Peter’s case) does not necessarily destroy the body. The two are real, distinguishable, and can be affected differently.

Fourth, Paul’s prayer for Timothy’s spirit (2 Tim. 4:22) connects to the broader Pauline anthropological framework in 1 Thessalonians 5:23, where Paul distinguishes “spirit, soul, and body” (treated in Chapter 15), and to the inner/outer person distinction in 2 Corinthians 4:16 and Ephesians 3:16 (treated in Chapter 16). Paul consistently writes as if the human person has an immaterial interior that is the primary location of divine encounter and moral agency.56

Finally, the psalmist’s cry that his soul “thirsts for God” (Ps. 42:1–2, treated in Chapter 8) resonates deeply with Peter’s pilgrimage language. The soul is a traveler, longing for its true home in God’s presence. Peter and the psalmist are describing the same existential reality from different angles—and both assume that the soul is the deepest, most God-directed part of the human person.

E. Pastoral Implications

These passages are not just data points for a theological argument. They are words that have sustained real believers through real suffering for two thousand years.

When Peter told those persecuted Christians in Asia Minor to “commit their souls” to a faithful Creator, he was telling them something profoundly comforting: even if the worst happens to your body, your deepest self is safe with God. That is not a message you can give on a physicalist anthropology. If there is no soul, there is nothing to commit to God’s care. If the person ceases to exist entirely at death (until the future resurrection), then Peter’s instruction is hollow. “Commit your soul to God” becomes “Hope that God remembers you.” That is a very different kind of comfort.57

When Paul prayed that the Lord be with Timothy’s spirit, he was reminding his young protégé that the most important battles are fought on the inside. The spirit is where Christ meets us, sustains us, and empowers us. If the spirit is not a real dimension of the person, then Paul’s closing words are little more than a warm sentiment. But if the spirit is real—if it is the immaterial core where the believer encounters the living God—then Paul’s prayer carries the weight of eternity.58

And when John assured his readers that God is greater than their condemning hearts, he was pointing to a truth that only makes sense on a dualist view: God has direct access to the inner self. He does not merely observe our behavior from the outside. He enters the innermost chambers of the heart, knows what we cannot put into words, and speaks assurance where guilt tries to rule. A physicalist God—one who relates only to the physical organism—cannot offer this kind of intimacy. But the God of the Bible relates to the soul. He is its Creator, its Redeemer, and its final home.

A Note to CI Readers: Nothing in this chapter threatens conditional immortality. The soul’s reality does not require the soul’s inherent immortality. God created the soul, God sustains the soul, and God can destroy the soul (Matt. 10:28). CI and substance dualism are not only compatible; they are natural partners. The soul is real, but it is not indestructible. Its continued existence depends entirely on the will and grace of God.59

The physicalist reading of these passages may seem harmless at first glance. What does it matter whether the soul is “real” or “just a way of talking about the person”? It matters because it shapes how we understand every aspect of the Christian life: what salvation does, how spiritual warfare works, what we commit to God in suffering, and where we meet Christ in prayer. Get the anthropology wrong, and the whole picture shifts. The pilgrimage of the soul becomes merely the movement of a body through time. The warfare against the soul becomes merely a neural struggle with no deeper dimension. The committal of the soul to God becomes merely a hopeful gesture with no object.

That is not what Peter, Paul, and John were teaching. They were teaching that we are more than bodies. We are pilgrims with souls, warriors with spirits, and people whose hearts are known by God. That is the anthropology that sustains the church through persecution, through grief, through death, and through the long wait for the resurrection morning when body and soul will finally be reunited in glory.

Notes

1. On the overlap of “heart,” “soul,” and “spirit” as designations for the inner person in the New Testament, see Cooper, Body, Soul, and Life Everlasting, chap. 5, “The New Testament Evidence”; Moreland, The Soul: How We Know It’s Real and Why It Matters (Chicago: Moody, 2014), chaps. 3–4.

2. Of the six passages treated in this chapter, Fudge discussed 1 Peter 1:9 and 1 Peter 4:19 in the context of the Petrine material on judgment and the fate of the wicked (see Fudge, The Fire That Consumes, pp. 223–225). The remaining four passages—1 Peter 2:11; 2 Timothy 4:22; Philippians 1:27; and 1 John 3:20—are not treated in his book.

3. The Greek telos carries the sense of “goal,” “end,” or “outcome.” In this context, it denotes the culmination of the faith journey—the final result toward which saving faith is directed. See Walter Bauer, William F. Arndt, F. Wilbur Gingrich, and Frederick W. Danker, A Greek-English Lexicon of the New Testament and Other Early Christian Literature, 3rd ed. (Chicago: University of Chicago Press, 2000), s.v. telos.

4. For the semantic range of psychē in the New Testament, see BDAG, s.v. psychē. Meanings include “life,” “living creature,” “person,” “the seat of feelings, desires, affections,” and “the soul as distinct from the body.”

5. This reflects Fudge’s broader approach to anthropological terms throughout The Fire That Consumes, esp. pp. 25–30, where he draws heavily on the work of Hans Walter Wolff and Aimo T. Nikolainen to argue that nephesh/psychē refers to the whole person rather than an immaterial entity.

6. Cooper makes a similar argument about contexts where the physical body is threatened or destroyed: in such situations, the use of psychē to designate the object of salvation distinguishes the soul from the body and implies that salvation addresses a dimension of the person that transcends physical existence. See Cooper, Body, Soul, and Life Everlasting, chap. 5.

12. Fudge, The Fire That Consumes, pp. 223–225. His discussion of the Petrine epistles focuses on 1 Peter 4:17–18 and 2 Peter 2:1–22 and their implications for final punishment.

13. Paroikos means “resident alien,” someone living in a place that is not their permanent home. Parepidēmos means “sojourner” or “stranger,” one who is passing through. See BDAG, s.v. paroikos and parepidēmos.

14. BDAG, s.v. strateuomai: “to serve as a soldier,” and in the middle voice, “to wage war against.” The military metaphor is unmistakable. Peter portrays the soul as a territory under siege.

15. Schreiner comments: “The warfare language indicates that the soul is a genuine objective reality under assault—not merely a metaphorical reference to the person.” See Schreiner, 1, 2 Peter, Jude, 123.

16. Moreland, The Soul, chap. 4. Moreland argues that the framework of spiritual warfare in the New Testament presupposes the existence of an immaterial soul as the arena of moral and spiritual conflict.

17. The pilgrimage metaphor in 1 Peter has deep roots in the Old Testament—cf. Abraham as a sojourner (Gen. 23:4; Heb. 11:13), and the Psalms of Ascent (Pss. 120–134). In each case, the faithful are people whose deepest identity is not tied to their present physical location. The soul is the pilgrim.

19. A thorough search of Fudge’s The Fire That Consumes reveals no treatment of 1 Peter 2:11 or its anthropological implications.

20. BDAG, s.v. paratithēmi: “to entrust for safekeeping, give over, deposit.” The word was used in legal and banking contexts for entrusting valuables to a custodian.

21. Luke 23:46, quoting Psalm 31:5. Jesus’ use of paratithēmi on the cross (with pneuma) and Peter’s use of paratithēmi here (with psychē) are clearly connected. Peter’s readers are to follow Jesus’ example: deposit the immaterial self with God.

22. On the connection between Jesus’ dying words and Peter’s instruction in 4:19, see Grudem, 1 Peter, 192–193.

23. Compare Matthew 10:28: “Do not fear those who kill the body but cannot kill the soul.” The logic is identical: the body can be destroyed by human agents, but the soul belongs to a different category and is safe with God.

24. Cooper, Body, Soul, and Life Everlasting, chap. 5. Cooper emphasizes that the soul’s continued existence depends entirely on God’s sustaining will—it is created, not self-existent. This distinguishes Christian substance dualism from Platonic immortality.

25. Cooper, Body, Soul, and Life Everlasting, chaps. 3–5. Cooper traces the tradition of “committing the spirit/soul to God” from David through Jesus to the apostolic church and argues that it presupposes a separable soul or spirit.

27. Fudge, The Fire That Consumes, pp. 223–225. Fudge’s treatment of the 1 Peter 4 material focuses on vv. 17–18 and the question of what will become of the ungodly, not on v. 19 and its anthropological significance.

28. On the setting of 2 Timothy as Paul’s final letter, see William D. Mounce, Pastoral Epistles, Word Biblical Commentary 46 (Nashville: Thomas Nelson, 2000), lxiii–lxxvii.

29. That pneuma here refers to Timothy’s human spirit rather than the Holy Spirit is confirmed by the possessive pronoun sou (“your”). Paul prays for Christ to be present with Timothy’s spirit specifically. See Mounce, Pastoral Epistles, 596.

30. The pattern of Pauline “spirit benedictions” includes Galatians 6:18, Philippians 4:23, Philemon 25, and 2 Timothy 4:22. In each case, Paul directs his prayer to “your spirit” rather than “you,” suggesting a deliberate focus on the immaterial inner self.

31. Cooper, Body, Soul, and Life Everlasting, chap. 2, “Old Testament Anthropological Terms.” Cooper acknowledges synecdoche as a real phenomenon but argues against applying it indiscriminately to every occurrence of psychē, pneuma, or kardia.

32. Moreland, The Soul, chap. 4. Moreland argues that the distinction between “you” and “your spirit” in Pauline benedictions is evidence that Paul regarded the spirit as a distinguishable dimension of the person, not merely a synonym for the whole self.

33. On the significance of Paul’s impending death as the background for 2 Timothy 4:22, see Philip H. Towner, The Letters to Timothy and Titus, New International Commentary on the New Testament (Grand Rapids: Eerdmans, 2006), 643–644.

35. A search of Fudge’s The Fire That Consumes reveals no treatment of 2 Timothy 4:22.

36. The Greek text of Philippians 1:27 uses both pneuma and psychē in a single clause: stēkete en heni pneumati, mia psychē synathloutes tē pistei tou euangeliou.

37. The NKJV translates mia psychē as “with one mind,” interpreting psychē as the seat of thought and will. The ESV marginal note offers “soul.” The NIV renders it “as one” with a note suggesting “with one mind and purpose.” Regardless of translation, the anthropological term psychē is present in the Greek.

38. For the view that pneuma in Phil. 1:27 refers to the Holy Spirit, see Fee, God’s Empowering Presence, 745–748. Fee argues that the “one Spirit” is the Holy Spirit who unites the community.

39. Even on Fee’s reading, the psychē in the second clause is anthropological. Paul calls for unity at the level of the soul—the inner life of will and commitment.

40. On Paul’s layered anthropology, see Cooper, Body, Soul, and Life Everlasting, chap. 6, “The Pauline Evidence.”

46. The heart as the seat of conscience and moral judgment is a well-established theme in both Testaments. See Romans 2:15 (“the work of the law written in their hearts, their conscience also bearing witness”); Jeremiah 17:10 (“I, the LORD, search the heart”); and Psalm 139:23 (“Search me, O God, and know my heart”).

47. Moreland and Rae argue that the Bible’s heart language presupposes a genuine interiority that cannot be reduced to physical brain processes. See J. P. Moreland and Scott B. Rae, Body & Soul: Human Nature and the Crisis in Ethics (Downers Grove, IL: InterVarsity Press, 2000), 22–25.

48. On the Johannine theme of divine indwelling and the interior life of the believer, see Raymond E. Brown, The Epistles of John, Anchor Bible 30 (Garden City, NY: Doubleday, 1982), 457–461.

50. A search of Fudge’s The Fire That Consumes reveals no treatment of 1 John 3:20.

51. This summary draws together the key finding of each exposition. The cumulative weight of six passages across multiple authors, all treating the soul as a genuine entity, constitutes strong evidence for the pervasive dualism of the New Testament anthropological vocabulary.

52. Cooper, Body, Soul, and Life Everlasting, chap. 5. Cooper emphasizes the cumulative argument: individual terms may be ambiguous, but the overall pattern of New Testament usage consistently supports substance dualism.

53. Rickabaugh and Moreland, The Substance of Consciousness, chap. 6, “Biblical Anthropology.”

54. Cooper, Body, Soul, and Life Everlasting, chap. 2. Cooper’s warning about the over-application of synecdoche is one of the most important methodological observations in the entire book. See also the discussion of synecdoche in Chapter 5 of the present work.

55. The connection between Mark 8:36–37 and 1 Peter 1:9 is significant because it shows that the same anthropological assumption—the soul as the most valuable dimension of the person—is shared by Jesus and Peter.

56. See Chapter 15 (1 Thessalonians 5:23) and Chapter 16 (2 Corinthians 4:16; Ephesians 3:16) for the detailed treatment of these passages.

57. Cooper, “Absent from the Body … Present with the Lord,” in Christian Physicalism, chap. 16. Cooper argues that the pastoral power of the intermediate state doctrine depends on the reality of the soul’s conscious existence between death and resurrection.

58. On the pastoral significance of Paul’s spirit-benedictions, see Towner, The Letters to Timothy and Titus, 644.

59. This is the central thesis of the book: CI does not require physicalism, and substance dualism actually strengthens the CI position. The soul is real, created, and dependent on God—not inherently immortal. See Chapters 2 and 31 for the full argument.

60. On the problems with the “accommodation” argument as applied to biblical anthropology, see Cooper, Body, Soul, and Life Everlasting, chap. 4, where he argues that the anthropological framework of the biblical writers is integral to their theological message, not merely cultural scaffolding that can be discarded. See also Rickabaugh and Moreland, The Substance of Consciousness, chap. 6.

61. On the compatibility of the soul’s existence with the centrality of bodily resurrection, see Cooper, Body, Soul, and Life Everlasting, chap. 7, “Resurrection and the Body-Soul Problem.” Cooper argues that substance dualism does not diminish the importance of the resurrection; rather, it provides the metaphysical basis for personal continuity between death and resurrection. Farris makes a similar point: see Joshua R. Farris, “Substance Dualism,” in The Soul of Theological Anthropology, chap. 2.

62. Augustine, Confessions, III.6.11. Augustine’s language of God being “more inward to me than my most inward part” (interior intimo meo) presupposes a real interiority—a genuine inner self that God can inhabit and know. This is the patristic tradition’s understanding of the soul as the primary locus of the divine-human encounter.

63. The eschatological framework of 1 Peter 1:3–9 distinguishes between what is happening to the body now (suffering, testing) and what is being secured for the soul (salvation, inheritance). See Schreiner, 1, 2 Peter, Jude, 64–72, for a full treatment of the eschatological context.
