Chapter 36
The Atonement Applied — Justification, Reconciliation, and Redemption

Introduction: From the Cross to the Christian

We have spent the greater part of this book examining what happened at the cross—what Christ accomplished when He died for the sins of the world. We have traced the biblical language of atonement through the Old and New Testaments. We have followed the historical development of atonement theology from the earliest Church Fathers through the Reformation and into our own day. We have defended substitutionary atonement against philosophical objections and answered theological critiques from multiple traditions. But now a crucial question confronts us: What difference does it all make?

What good is an accomplished atonement if it remains, so to speak, locked up at Golgotha? The cross was not an end in itself. It was God's decisive act to rescue human beings from sin, death, and condemnation—and to bring them into a living, restored relationship with Himself. So in this chapter, we turn from the objective work of Christ on the cross to the subjective benefits that flow from it to all who trust in Him. We move from atonement accomplished to atonement applied.

I want to be clear about what I mean by "applied." The atonement was a finished work—a once-for-all event that took place at a particular moment in history when Jesus of Nazareth died on a Roman cross outside the walls of Jerusalem. Nothing needs to be added to it. But its benefits must be received. A cure sitting in a bottle on a shelf does no one any good until the patient takes it. In the same way, the saving effects of Christ's death must be personally appropriated by faith. And when they are, something extraordinary happens. The New Testament uses a rich constellation of terms to describe what Christ's death accomplishes in the lives of believers: justification, reconciliation, redemption, propitiation, adoption, sanctification, and new creation. Each of these terms captures a different facet of the diamond, a different dimension of what Christ has won for us.¹

John Stott captures this beautifully when he observes that the images of salvation in Scripture are like the images used to describe the church—visually incompatible with one another, yet each contributing an essential truth to the whole. Propitiation introduces us to the rituals of the temple. Redemption takes us into the marketplace. Justification brings us before a judge in a court of law. Reconciliation leads us home to our family. These are not competing theories to choose from but complementary pictures that together display the breathtaking scope of what God has done for us in Christ.²

My thesis in this chapter is straightforward: the atonement, objectively accomplished in Christ's death, produces a constellation of saving benefits—justification, reconciliation, redemption, propitiation, adoption, sanctification, and new creation—that together describe the full scope of what Christ has won for those who trust in Him. And I want to show how substitutionary atonement provides the central mechanism that makes all of these benefits possible. Because Christ stood in our place and bore the consequences of our sin, the legal barrier between God and humanity has been removed, reconciliation has been achieved, liberation has been accomplished, and the way has been thrown open for every other spiritual blessing to flow into the life of the believer.

As David Allen helpfully distinguishes, atonement and salvation are related but not identical concepts. Atonement refers specifically to what Christ accomplished on the cross with respect to God, humanity, and sin. Salvation covers the actual results of that atonement when it is applied to the believer—justification, reconciliation, redemption, adoption, and all the rest. Salvation includes atonement; atonement is the basis for salvation. The two are inseparable but not interchangeable.³

Let us now examine each of these saving benefits in turn, beginning with what I regard as the most immediately relevant fruit of substitutionary atonement: justification.

Justification: Declared Righteous Before God

Of all the benefits that flow from the cross, justification is the one most directly and immediately connected to substitutionary atonement. If Christ bore the penalty for our sins in our place, then God can justly declare sinners righteous—not because they have earned it, not because they deserve it, but because the judicial consequences of their sin have already been dealt with at the cross. Justification is, in a real sense, the most direct soteriological fruit of Christ's substitutionary death.

But what exactly is justification? The Greek term is dikaiōsis (δικαίωσις), and it is a legal word—a courtroom term. It is the opposite of condemnation. Paul makes this crystal clear in Romans 8:33–34: "Who shall bring any charge against God's elect? It is God who justifies. Who is to condemn? Christ Jesus is the one who died—more than that, who was raised—who is at the right hand of God, who indeed is interceding for us" (ESV). In a courtroom, the judge either condemns the accused or acquits them. Justification is the verdict of acquittal—but it is even more than that. It is not merely a declaration that the accused is "not guilty." It is a positive declaration that the accused has a righteous standing before God.⁴

This distinction matters enormously. Forgiveness by itself simply wipes the slate clean—it cancels our debt. But justification goes further. It credits righteousness to our account. Paul puts it this way in Romans 4:5–8:

"And to the one who does not work but believes in him who justifies the ungodly, his faith is counted as righteousness, just as David also speaks of the blessing of the one to whom God counts righteousness apart from works: 'Blessed are those whose lawless deeds are forgiven, and whose sins are covered; blessed is the man against whom the Lord will not count his sin'" (ESV).

Notice the remarkable logic here. God "justifies the ungodly." That is a shocking statement. In the Old Testament, Proverbs 17:15 declares that "he who justifies the wicked" is "an abomination to the LORD." And yet Paul says that God does precisely this—He justifies the ungodly. How can this be? How can a holy God declare unrighteous people to be righteous without contradicting His own justice?

The answer lies in substitution. God does not simply overlook sin or pretend it never happened. He deals with it—decisively, fully, and at immense cost to Himself. As we argued in Chapter 19, Christ bore in our place the judicial consequences that our sins deserved. And because the penalty has been paid, God can now "be just and the justifier of the one who has faith in Jesus" (Romans 3:26, ESV). The cross upholds God's justice even as it extends God's mercy. This is not amnesty—a pardon without principle. It is, as J. I. Packer memorably defined it, "God's gracious work of bestowing upon guilty sinners a justified justification, acquitting them in the court of heaven without prejudice to his justice as their Judge."⁵

The Source, Ground, and Means of Justification

Stott helpfully identifies three dimensions of justification that Paul develops in Romans. First, the source of our justification is God's grace. We are "justified by his grace as a gift" (Romans 3:24, ESV). Justification is not earned; it is freely given. We contribute nothing. As William Temple once said, the only thing of our very own that we contribute to our redemption is the sin from which we need to be redeemed.⁶

Second, the ground of our justification is Christ's blood—that is, His atoning death. We are "justified by his blood" (Romans 5:9, ESV). Grace alone tells us the source of justification, but it does not tell us the righteous basis on which God can justify sinners. The cross provides that basis. Because Christ's death was a substitutionary sacrifice—because He bore the consequences of our sin in our place—God has a just ground on which to pronounce sinners righteous. Justification is not a legal fiction. It is grounded in a real, historical, substitutionary event.⁷

Third, the means of our justification is faith. We are "justified by faith" (Romans 5:1, ESV). Faith does not earn justification—it simply receives what grace offers on the basis of what Christ has done. As Richard Hooker put it with characteristic precision, "God doth justify the believing man, yet not for the worthiness of his belief, but for his worthiness who is believed."⁸ Faith is the empty hand that receives the gift. It is the channel, not the cause, of our right standing before God.

The sixteenth-century Reformers rightly recognized the centrality of this doctrine. Luther called justification by faith "the principal article of all Christian doctrine." And the Reformers were not inventing something new. As we noted in Chapter 17, the doctrine of justification by faith goes back through the New Testament to Jesus Himself, who told the parable of the tax collector and the Pharisee and concluded that the tax collector "went down to his house justified" (Luke 18:14, ESV). Even further back, Isaiah declared that God's righteous Servant "will justify many" because "he will bear their iniquities" (Isaiah 53:11, ESV)—a direct connection between substitutionary sin-bearing and the justification of sinners.⁹

Justification and Imputation

A key concept closely tied to justification is imputation—the crediting or reckoning of something to someone's account. Paul uses the Greek verb logizomai (λογίζομαι), a bookkeeping term meaning "to reckon" or "to credit," eleven times in Romans 4 alone. Abraham "believed God, and it was counted to him as righteousness" (Romans 4:3, ESV, quoting Genesis 15:6). Faith was "counted" or "credited" to Abraham—not because faith is itself a meritorious work, but because faith lays hold of God's promise and God graciously reckons it as righteousness.

The logic of imputation works in two directions. Our sin is imputed to Christ—laid on Him, so that He bears its consequences. And Christ's righteousness is imputed to us—credited to our account, so that we stand before God clothed not in our own righteousness but in His. Paul captures this breathtakingly in 2 Corinthians 5:21: God "made him to be sin who knew no sin, so that in him we might become the righteousness of God." This "great exchange," as it has been called, is the beating heart of the gospel. It only makes sense within a substitutionary framework. If Christ did not truly stand in our place, if He did not truly bear our sin, then there is no basis for the transfer—no ground on which God can credit us with a righteousness that is not originally our own.¹⁰

I want to stress that this does not make justification a mere legal fiction, as some critics allege. The believer who is justified is also united to Christ by faith—grafted into Him, so to speak. And because the believer is "in Christ," the righteous standing that Christ has earned becomes genuinely theirs. It is not a pretense. It is a real status grounded in a real union. As we explored in Chapter 28, the concept of corporate solidarity and union with Christ means that what is true of Christ becomes, in a genuine sense, true of those who are in Him.

It is worth pausing here to note that the doctrine of justification has been a major point of both division and dialogue between Protestants and Roman Catholics since the Reformation. The Council of Trent (1545–1563) taught that justification takes place at baptism and includes both forgiveness of sins and an infusion of new, supernatural righteousness—so that justification involves not only a declaration but a real inner transformation. The Protestant Reformers, by contrast, insisted that justification is a purely forensic act—God's declaration of the sinner's righteous status, distinct from the process of inner renewal (which they called sanctification). Hans Küng's remarkable monograph on Karl Barth's doctrine of justification opened fresh possibilities for dialogue by arguing that the Catholic and Protestant positions are closer than either side had recognized. Küng affirmed that justification is "a declaring just by court order" and that it happens "by faith alone"—statements that sound remarkably Protestant. Yet Küng also insisted that God's declaration is always efficacious, so that when God pronounces someone just, they are genuinely made just in the same act.³⁴

I believe the key to clarity here lies in distinguishing carefully between justification and sanctification. When God declares us righteous through Christ, that declaration takes effect immediately and completely—we are fully justified the moment we believe. But the process of actually becoming righteous in our character and conduct—sanctification—is gradual and lifelong. It begins at the moment of justification but will not be completed until the resurrection. Confusing these two categories leads to confusion about the gospel itself. The beauty of justification is precisely that it is complete and undeserved—a gift of grace received by faith, not a process of moral improvement. This does not make the moral transformation any less real or important; it simply means that our standing before God does not depend on the degree of our sanctification but on the finished work of Christ.³⁵

Justification and Substitutionary Atonement

I want to make the connection between justification and substitutionary atonement as explicit as possible. Consider Paul's compressed statement in Romans 3:24–26:

"...and are justified by his grace as a gift, through the redemption that is in Christ Jesus, whom God put forward as a propitiation by his blood, to be received by faith. This was to show God's righteousness, because in his divine forbearance he had passed over former sins. It was to show his righteousness at the present time, so that he might be just and the justifier of the one who has faith in Jesus" (ESV).

Notice how Paul weaves together justification, redemption, and propitiation in a single sentence. As argued in Chapter 8, this passage is one of the most theologically dense statements in all of Scripture. God justifies sinners freely by His grace. The ground of that justification is the redemption accomplished in Christ Jesus. And the mechanism by which that redemption works is propitiation—Christ's blood turning aside the just consequences of sin. The whole structure depends on substitution: Christ in our place, bearing what we deserved, so that we might receive what He deserved.

Stott makes the point brilliantly: "When God justifies sinners, he is not declaring bad people to be good, or saying that they are not sinners after all; he is pronouncing them legally righteous, free from any liability to the broken law, because he himself in his Son has borne the penalty of their law-breaking."¹¹ There could be no justification without atonement. And there could be no atonement without substitution.

Reconciliation: The Relationship Restored

If justification answers the question "What is my legal standing before God?", reconciliation answers the question "What is my personal relationship with God?" These two benefits of the cross are closely related—Paul treats them as parallels in Romans 5:9–11—but they are not identical. Justification is a courtroom word; reconciliation is a family word. We move now from the judge's bench to the family hearth. And this, for many people, is the image of salvation that resonates most deeply.¹²

The Greek term for reconciliation is katallagē (καταλλαγή), and the verb is katallassō (καταλλάσσω). At its most basic, to reconcile means to restore a broken relationship—to bring together two parties who have been estranged. In the New Testament, the relationship in view is between God and human beings, which has been shattered by sin. As Paul puts it in Romans 5:10: "For if while we were enemies we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life" (ESV).

Two things stand out in this verse. First, the starting point of reconciliation is enmity. We were "enemies" of God. This is not a mild estrangement; it is a deep and thorough alienation caused by human sin and rebellion. Sin does not merely disappoint God or make Him sad. It creates a real barrier—a genuine rupture in the relationship between the holy Creator and His sinful creatures. Second, the means of reconciliation is the death of Christ. We were reconciled "by the death of his Son." The cross bridges the gap that sin created.

God Is the Author of Reconciliation

One of the most striking features of the New Testament's teaching on reconciliation is that God Himself is the one who initiates it. We did not reconcile ourselves to God. We did not climb up to heaven and negotiate a peace treaty. God came down to us. This is the emphatic point of Paul's great reconciliation passage in 2 Corinthians 5:18–21:

"All this is from God, who through Christ reconciled us to himself and gave us the ministry of reconciliation; that is, in Christ God was reconciling the world to himself, not counting their trespasses against them, and entrusting to us the message of reconciliation. Therefore, we are ambassadors for Christ, God making his appeal through us. We implore you on Christ's behalf, be reconciled to God. For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God" (ESV).

As Stott observes, eight verbs in this passage have God as their subject. God reconciling. God giving. God appealing. God making Christ to be sin for us. From first to last, this is the work of God. No explanation of the atonement is genuinely biblical which takes the initiative away from God and gives it to us or even to Christ in such a way as to diminish the Father's role. The Father and the Son act together in love—a point we developed at length in Chapter 20.¹³

The Scope of Reconciliation

The New Testament speaks of reconciliation in three dimensions. First and foundationally, there is reconciliation between God and individual sinners. This is the meaning of atonement in its most basic sense—to make "at one" those who have been estranged. When a person trusts in Christ, the enmity between them and God is ended, the barrier of sin is removed, and they are brought into a living, personal relationship with their Creator.

Second, there is reconciliation between human beings. In Ephesians 2:11–22, Paul describes how the cross has broken down the "dividing wall of hostility" between Jews and Gentiles, creating "one new man in place of the two, so making peace" (Ephesians 2:14–15, ESV). The cross does not only reconcile individuals to God; it reconciles them to one another. In Christ, every barrier of race, class, and culture is transcended. The church, at its best, is a living demonstration of the reconciling power of the cross.¹⁴

Third, there is cosmic reconciliation. In Colossians 1:19–20, Paul writes that God was pleased "through him to reconcile to himself all things, whether on earth or in heaven, making peace by the blood of his cross" (ESV). The scope of reconciliation extends beyond individual souls and even beyond human community to encompass the entire created order. The cross has cosmic significance. As we argued in Chapter 21, the Christus Victor dimension of the atonement—Christ's victory over the hostile powers—is closely connected to this cosmic reconciliation. The principalities and powers have been disarmed (Colossians 2:15), and the creation itself will one day be liberated from its bondage to decay (Romans 8:21).¹⁵

Reconciliation and Substitution

How does substitutionary atonement relate to reconciliation? The connection is direct and essential. The reason we needed reconciliation in the first place was that sin had created a barrier between us and God—a barrier of guilt, of broken law, of divine justice that demands a response to evil. Substitutionary atonement removes that barrier. Because Christ bore in our place the consequences of our sin, the offense has been dealt with, the guilt has been absorbed, and the way back to God has been thrown open.

Philippe de la Trinité, writing from a Roman Catholic Thomistic perspective, makes a closely related point. He insists that reconciliation is accomplished not through God venting His rage on an innocent victim but through the Son's voluntary self-offering in love and obedience, in union with the Father. The cross is "vicarious satisfaction"—the Son satisfying the demands of justice on our behalf, not under the Father's wrath, but in the Father's love. The result is the restoration of the relationship between God and humanity—reconciliation in the fullest sense.¹⁶

I find this deeply compelling. Reconciliation is not merely a byproduct of the cross. It is one of its primary purposes. God's goal was never simply to balance a legal ledger. His goal was to bring His children home. And substitutionary atonement is the means by which He accomplished that homecoming.

It is worth noting, too, that reconciliation has profound practical implications. Paul does not treat reconciliation as an abstract theological concept; he immediately connects it to a mission: "Therefore, we are ambassadors for Christ, God making his appeal through us. We implore you on Christ's behalf, be reconciled to God" (2 Corinthians 5:20, ESV). Those who have been reconciled are now called to become agents of reconciliation—both proclaiming the message that God has dealt with sin through the cross and embodying the reconciling love of God in their relationships with others. The church, as the reconciled community, is meant to be a living preview of the fully reconciled world that God is bringing about through the cross. When Christians forgive one another, when they bridge racial and cultural divides, when they overcome enmity with love, they are putting the reconciling power of the cross on display for the watching world.³⁹

Two related terms confirm the relational richness of reconciliation: adoption and access. Reconciliation means that we are no longer enemies or strangers—we are children of God (adoption) with free and confident access to the Father's presence (access). Paul writes in Ephesians 2:18 that "through him we both have access in one Spirit to the Father" (ESV). Access—the Greek word is prosagōgē (προσαγωγή)—describes the privilege of drawing near to God in prayer, worship, and fellowship. This is a Trinitarian experience: we come to the Father, through the Son, by the Spirit. And it is made possible by the cross. As the writer of Hebrews urges: "Let us then with confidence draw near to the throne of grace" (Hebrews 4:16, ESV). That confidence is grounded not in our own worthiness but in the finished atoning work of Christ.

Redemption: Liberation from Bondage

We turn now to a third great benefit of the cross: redemption. If justification takes us into a courtroom and reconciliation takes us into a home, redemption takes us into a marketplace—specifically, the ancient slave market. For at its most basic, to "redeem" means to buy back, to purchase someone's freedom, to liberate a captive by paying a price. The Greek terms are lytroō (λυτρόω, "to redeem"), apolytrōsis (ἀπολύτρωσις, "redemption"), and lytron (λύτρον, "ransom" or "price of release")—words that were almost technical terms in the ancient world for the purchase or manumission of a slave.¹⁷

The language of redemption emphasizes the sorry condition from which we needed to be rescued. We were captives. We were enslaved. And unlike justification, which focuses primarily on the legal dimension of our problem, redemption focuses on the experiential dimension—the felt reality of bondage to sin, death, and the powers of evil. Every person who has ever struggled with a destructive habit, a persistent temptation, or a seemingly unbreakable cycle of failure knows something of what this bondage feels like. The gospel declares that Christ has purchased our freedom.

Redemption in the Old Testament

The concept of redemption runs deep in the Old Testament. In ancient Israel, property, animals, and even persons could be "redeemed"—bought back—by the payment of a price. The kinsman-redeemer (go'el, גֹּאֵל) had the right and even the duty to buy back a relative's alienated property, to free a relative who had been sold into slavery, or to avenge a relative's blood. The most beautiful illustration of this is Boaz, who redeemed Ruth and her family inheritance—a story that foreshadows the greater Redeemer who would one day purchase His people at an infinitely greater cost.¹⁸

But the most foundational act of redemption in the Old Testament was God's deliverance of Israel from slavery in Egypt. The Exodus was the defining redemptive event of Israel's national life, and the vocabulary of redemption saturates the biblical accounts of it. God redeemed Israel "with an outstretched arm" and "with a mighty hand" (Exodus 6:6; Deuteronomy 7:8, ESV). Even here, as B. B. Warfield argued, the concept of costly payment is present: God's redemption of Israel cost the exertion of immense divine power and, in the Passover itself, the blood of a substitute lamb.¹⁹

Redemption in the New Testament

When we cross into the New Testament, the concept of redemption undergoes a dramatic intensification. The plight from which we need to be redeemed is now revealed as moral rather than merely physical, and the price of that redemption is not silver or gold but the blood of God's own Son.

The foundational text is Jesus' own statement in Mark 10:45: "For even the Son of Man came not to be served but to serve, and to give his life as a ransom for many" (ESV). The Greek expression here is lytron anti pollōn (λύτρον ἀντὶ πολλῶν)—literally, "a ransom in the place of many." As we argued in Chapter 7, the combination of lytron ("ransom") with anti ("in the place of") makes the substitutionary meaning unmistakable. Jesus understood His own death as a ransom paid on behalf of others—a price surrendered so that captives might go free.²⁰

Peter makes the same connection with striking vividness:

"...knowing that you were ransomed from the futile ways inherited from your forefathers, not with perishable things such as silver or gold, but with the precious blood of Christ, like that of a lamb without blemish or spot" (1 Peter 1:18–19, ESV).

The contrast is deliberate and powerful. Silver and gold are perishable—they corrode, they lose their value, they belong to the passing world. But the blood of Christ is the most precious substance in the universe, offered by One who was utterly without blemish or defect. The cost of our redemption was nothing less than the life of the Son of God.

Paul adds another layer. In Ephesians 1:7, he writes: "In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace" (ESV). And in Galatians 3:13: "Christ redeemed us from the curse of the law by becoming a curse for us—for it is written, 'Cursed is everyone who is hanged on a tree'" (ESV). Here the substitutionary logic is on full display. Christ redeemed us by becoming what we were—cursed, condemned by the law—so that we might become what He is—blessed, righteous, free. As explored in Chapter 9, this is one of Paul's most powerful substitutionary statements.

The Three Dimensions of Redemption

Stott identifies three emphases in the biblical concept of redemption. First, there is the plight from which we are redeemed. The New Testament describes this variously as bondage to sin and transgression (Ephesians 1:7; Colossians 1:14), the curse of the law (Galatians 3:13), and the "futile ways" inherited from our ancestors (1 Peter 1:18). The human condition apart from Christ is one of genuine captivity—held fast by forces we cannot overcome on our own.²¹

Second, there is the price with which we are redeemed. The New Testament never specifies to whom the ransom is paid—the early Church Fathers sometimes suggested it was paid to the devil, but this presses the imagery further than Scripture warrants. What Scripture does make clear is that the price was extraordinarily costly: the blood of Christ, the life of the Son of God, freely given. The emphasis falls not on the recipient of the payment but on the magnitude of the cost.

Third, there is the person of the redeemer who now has proprietary rights over those He has purchased. Because Christ bought us with His blood, we belong to Him. Paul draws the practical implication in 1 Corinthians 6:19–20: "You are not your own, for you were bought with a price. So glorify God in your body" (ESV). Our bodies are temples of the Holy Spirit, purchased at immense cost. We have no right to misuse what belongs to another. Redemption, then, is not merely liberation from something; it is liberation for Someone—for the service and worship of the God who rescued us.

There is also an important "already but not yet" dimension to redemption that we must not overlook. In one sense, our redemption is accomplished—a past event grounded in the finished work of the cross. We have redemption through His blood (Ephesians 1:7). But in another sense, our redemption is still future. Paul speaks of "the day of redemption" (Ephesians 4:30) and "the redemption of our bodies" (Romans 8:23). The full redemption of our physical bodies—and indeed of the entire groaning creation—awaits the return of Christ and the final resurrection. Until then, the indwelling Holy Spirit serves as the "guarantee" and "firstfruits" of our final redemption (Ephesians 1:14; Romans 8:23). We live between the decisive victory of the cross and its complete consummation at Christ's return. The price has been paid in full, but the full liberation it secured has not yet been experienced in every dimension. We are truly free from the guilt and dominion of sin, but we are not yet free from its presence. That final freedom is coming—and it is guaranteed by the blood of Christ already shed.³⁶

Redemption and Substitution

Here again the connection to substitutionary atonement is essential. Why does Christ's death function as a ransom? Because He died in our place. He took the penalty we owed. He bore the curse that was ours. He absorbed the consequences that should have fallen on us. The ransom is effective precisely because it is substitutionary. If Christ's death were merely a moral example or an inspiring display of love, it could not actually free us from our bondage. Only a genuine substitution—only someone actually stepping into our place and paying the price on our behalf—can break the chains.

Fleming Rutledge makes the connection powerfully when she writes that the redemption imagery in Scripture always presupposes a decisive and costly intervention. Someone must pay the price necessary to free the captive. In the case of our redemption from sin, that price is nothing less than the self-offering of the Son of God. The cross is not merely a symbol of love. It is the actual payment—the ransom price—by which our liberation was secured.²²

Propitiation: The Satisfaction of Divine Justice

The fourth benefit of the cross that we must consider is propitiation. This is perhaps the most controversial of the atonement terms, and we have treated it extensively in Chapter 8 in our analysis of Romans 3:25. I will therefore offer only a summary here, with a focus on how propitiation relates to the other benefits of the cross and to the overarching framework of substitutionary atonement.

The Greek terms are hilasmos (ἱλασμός) and hilastērion (ἱλαστήριον). As argued in Chapter 8, these terms carry propitiatory significance—they refer to the satisfaction or turning aside of God's just response to sin. Propitiation is not the placating of an arbitrary or capricious deity. It is the satisfaction of genuine divine justice by a God who Himself provides the sacrifice. As 1 John 4:10 makes clear: "In this is love, not that we have loved God but that he loved us and sent his Son to be the propitiation for our sins" (ESV). Propitiation originates in God's love, not in spite of it.²³

The point I want to emphasize here is that propitiation is the foundation on which all the other benefits rest. Stott arranges the images of salvation in a logical sequence: propitiation comes first, because until the just consequences of sin are dealt with, there can be no salvation at all. Then comes redemption (our rescue from captivity), justification (our righteous standing before God), and reconciliation (our restored relationship with the Father). All of these depend on propitiation—on the fact that Christ's substitutionary death has satisfied divine justice and opened the way for mercy to flow.²⁴

Again, I want to be clear about what propitiation does not mean, in keeping with the argument of Chapter 20. It does not mean that an angry Father poured out His rage on an unwilling Son. The Trinity acted in unified love at the cross. The Son went willingly. The Father was not an enraged deity but a loving God who, together with the Son and the Spirit, bore the cost of human sin. Philippe de la Trinité's formulation captures this well: Christ is "the victim of love"—a voluntary sacrifice offered in union with the Father, through obedience and love, not under duress or divine rage.²⁵

Adoption: Welcomed into God's Family

We come now to what may be the most tender and personally moving benefit of the cross: adoption. The Greek term is huiothesia (υἱοθεσία), which literally means "placing as a son." In the ancient Roman world, adoption was a legal act by which someone who was not naturally a member of a family was brought into it with all the rights and privileges of a natural-born child. The adopted person received a new name, a new identity, and a new inheritance.

Paul uses this image to describe what happens when a person trusts in Christ. Romans 8:15: "For you did not receive the spirit of slavery to fall back into fear, but you have received the Spirit of adoption as sons, by whom we cry, 'Abba! Father!'" (ESV). Galatians 4:4–5: "But when the fullness of time had come, God sent forth his Son, born of woman, born under the law, to redeem those who were under the law, so that we might receive adoption as sons" (ESV). Ephesians 1:5: "He predestined us for adoption to himself as sons through Jesus Christ, according to the purpose of his will" (ESV).

Notice the connection between redemption and adoption in Galatians 4:4–5. Christ was sent to redeem those under the law so that we might receive adoption. Adoption is not separate from the atoning work of Christ—it is its intended outcome. Christ bore the curse of the law (substitution) to free us from its bondage (redemption) so that we might become children of God (adoption). The legal removal of our guilt through Christ's substitutionary death makes our adoption possible. As long as we stood under condemnation, we could not stand as sons and daughters. The cross changed our status from condemned criminals to beloved children.²⁶

John captures the wonder of this in 1 John 3:1: "See what kind of love the Father has given to us, that we should be called children of God; and so we are" (ESV). That final phrase—"and so we are"—is John marveling at the reality. It is not just a title; it is the truth. We really are God's children. And this staggering identity is ours because of what Christ accomplished on the cross.

Sanctification: Being Made Holy

Justification is a declaration that happens in an instant—the moment a person trusts in Christ, they are declared righteous before God. But the Christian life does not end with justification. It continues with sanctification—the ongoing process by which the believer is transformed into the likeness of Christ. And here, too, the cross is the foundation.

The New Testament speaks of sanctification in two distinct senses. In one sense, sanctification is positional—it describes the believer's status as "set apart" for God. Hebrews 10:10 says: "And by that will we have been sanctified through the offering of the body of Jesus Christ once for all" (ESV). This is a completed action: we have been sanctified. Through the once-for-all sacrifice of Christ, believers are set apart as God's holy people. In this sense, every Christian is already a "saint"—not because of personal moral perfection, but because of Christ's atoning work.²⁷

In a second sense, sanctification is progressive—it describes the ongoing transformation of the believer's character and conduct. Hebrews 10:14 captures both dimensions in a single verse: "For by a single offering he has perfected for all time those who are being sanctified" (ESV). The first verb ("has perfected") is in the perfect tense—a completed action with ongoing results. The second verb ("are being sanctified") is in the present tense—an ongoing process. The cross provides both the legal basis (positional sanctification—we are set apart for God) and the transforming power (progressive sanctification—we are being conformed to Christ's image).

Paul makes the same point in 1 Corinthians 1:30: "And because of him you are in Christ Jesus, who became to us wisdom from God, righteousness and sanctification and redemption" (ESV). Christ Himself is our sanctification. He is not merely the One who makes sanctification possible; He is the substance of it. As we abide in Him, as we draw upon His grace, as His Spirit works within us, we are progressively transformed from glory to glory (2 Corinthians 3:18).

How does substitutionary atonement connect to sanctification? In two ways. First, the cross removes the barrier of guilt that separated us from the holy God who alone can make us holy. Until our sins were dealt with, we could not draw near to God—and without nearness to God, there is no sanctification. The substitutionary death of Christ opens the way into God's presence, making the transforming work of sanctification possible. The writer of Hebrews makes this connection explicit: "Therefore, brothers, since we have confidence to enter the holy places by the blood of Jesus, by the new and living way that he opened for us through the curtain, that is, through his flesh ... let us draw near" (Hebrews 10:19–22, ESV). The blood of the substitute opens the way to the presence of the holy God, and it is in that presence that transformation happens.

Second, the cross reveals the pattern of the Christian life. We are called to take up our own cross—to die to self, to put to death the deeds of the body (Romans 8:13), to live lives of self-giving love modeled on Christ's own sacrifice. The cross is both the foundation and the model of our holiness. Paul captures this powerfully in Galatians 2:20: "I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me" (ESV). The cross is not merely something that happened to Jesus for our benefit. It is something that happens to us—a death to the old self and a resurrection to new life in Christ. Substitutionary atonement provides the ground of our sanctification (the removal of guilt), while the cross as pattern provides the shape of our sanctification (the daily dying to self and rising to new life in Christ).

I should add that sanctification, like justification, is ultimately a Trinitarian work. The Father initiates it, the Son's atoning death makes it possible, and the Holy Spirit is the active agent who carries it out within the believer. Paul makes this clear in 2 Thessalonians 2:13: "God chose you as the firstfruits to be saved, through sanctification by the Spirit and belief in the truth" (ESV). The Spirit applies the benefits of Christ's atoning death to the daily life of the believer, progressively transforming them into the image of the Son. Without the cross, there would be no Spirit-wrought sanctification, because the barrier of sin that separated us from the holy God would remain in place. It is the atoning blood of Christ that clears the way for the Spirit's sanctifying work.³⁷

New Creation: All Things Made New

The final benefit of the cross I want to highlight is what Paul calls "new creation." In 2 Corinthians 5:17, he writes: "Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come" (ESV). This statement comes in the immediate context of Paul's discussion of reconciliation and substitutionary atonement (2 Corinthians 5:18–21), making it clear that new creation is a direct result of the cross.

What does it mean to be a "new creation"? It means that the atonement does not merely repair the old—it inaugurates something entirely new. The salvation Christ accomplished is not a patch on a worn-out garment. It is a whole new garment. It is not merely the forgiveness of the old life but the beginning of an entirely new one. The old order—characterized by sin, death, alienation, and condemnation—has passed away. A new order has dawned, characterized by righteousness, life, reconciliation, and freedom.

This language of "new creation" connects the atonement to the grand biblical narrative of creation, fall, and restoration. God created the world good. Sin corrupted it. And through the cross, God has begun the work of making all things new. The atonement is not just about saving individual souls—though it is certainly about that. It is about the renewal of the entire cosmos. Paul hints at this in Romans 8:19–23, where he describes the whole creation groaning as it waits for its final liberation from bondage to decay. The cross is the pivot point of that cosmic restoration.²⁸

This cosmic dimension of the atonement is one area where the Christus Victor model, discussed at length in Chapter 21, makes an indispensable contribution. Christ's death was not only a substitutionary sacrifice for individual sinners; it was a decisive victory over the powers of evil that hold the entire creation in bondage. Paul declares in Colossians 2:15 that Christ "disarmed the rulers and authorities and put them to open shame, by triumphing over them in him" (ESV). The cross defeated the dark powers that enslave and corrupt God's world. And because those powers have been defeated, the restoration of all things has begun. The new creation is not merely a future hope—it is a present reality that believers already participate in through their union with the risen Christ.

This is why the resurrection is so closely tied to the atonement in the New Testament's thinking. The cross deals with sin; the resurrection inaugurates new life. Christ was "delivered up for our trespasses and raised for our justification" (Romans 4:25, ESV). Without the resurrection, the cross would be a tragedy—the death of an innocent man. But the resurrection vindicates the cross and demonstrates that God has accepted Christ's sacrifice, defeated death, and launched the new creation. The empty tomb is God's declaration that the atonement has been accomplished, the old order has been broken, and the new age has dawned. Every time a sinner comes to faith in Christ, the new creation advances. Every act of justice, mercy, and love performed in Christ's name is a sign of the new world that the cross has inaugurated.

Rutledge captures this expansive vision when she insists that the cross is not merely a personal transaction between God and the individual sinner. It is the decisive event in God's war against all that defaces, destroys, and corrupts His good creation. The cross inaugurates the new creation—and one day, when Christ returns, that new creation will be brought to its completion.²⁹

Substitution at the Center: Why It All Depends on the Cross

We have now surveyed the major benefits of the atonement as they are described in the New Testament. But I want to return to the central argument of this book and show how substitutionary atonement provides the mechanism that makes all of these benefits possible.

Consider: Why can God justly declare sinners righteous? Because Christ bore the penalty of their sin in their place. Why can God reconcile sinners to Himself? Because the barrier of guilt and judgment has been removed by Christ's substitutionary sacrifice. Why can sinners be redeemed from bondage? Because Christ paid the ransom price with His own blood, standing in their place. Why has divine justice been satisfied? Because Christ, the sinless One, absorbed the consequences of human sin as our substitute. Why can sinners be adopted into God's family? Because Christ's substitutionary death removed the condemnation that barred them from sonship. Why can sinners be sanctified? Because Christ's sacrifice opened the way into God's holy presence. Why has new creation begun? Because the cross dealt the decisive blow to the old order of sin and death.

Strip away substitution, and the entire edifice collapses. If Christ did not truly stand in our place—if He did not truly bear what was due to us—then there is no basis for justification, no ground for reconciliation, no ransom for redemption, no satisfaction for divine justice, and no foundation for adoption, sanctification, or new creation. As Stott puts it with characteristic clarity: "If God in Christ did not die in our place, there could be neither propitiation, nor redemption, nor justification, nor reconciliation."³⁰ Substitution is not one theory among many. It is the foundation of them all.

This does not mean, of course, that substitution is the only thing that can be said about the cross. As we have argued throughout this book, the atonement is multi-faceted. Christus Victor, recapitulation, moral influence, and the other models each capture genuine dimensions of what Christ accomplished. But substitution is the hub around which the other spokes revolve. It is the center that holds everything together. Without it, the other images lose their power and coherence. With it, they all find their deepest meaning and their firmest grounding.

The Atonement Applied: Faith as the Means of Appropriation

One crucial question remains: How do the benefits of the cross become ours? The New Testament's answer is clear: through faith. We are justified by faith (Romans 5:1). We receive reconciliation through Christ (Romans 5:11). We have redemption in Him (Ephesians 1:7). Faith is the means by which the objective work of Christ becomes a subjective reality in the life of the believer.

But what is faith? It is not merely intellectual agreement—the bare acknowledgment that certain propositions are true. James 2:19 reminds us that even the demons "believe" in that minimal sense. Nor is faith a meritorious work that earns salvation. Faith is trust—a personal reliance on Christ and His finished work. It is the empty hand that receives the gift. It is the open mouth that takes the medicine. Faith does not contribute to salvation; it receives it.³¹

The Reformers captured this with the Latin phrase sola fide—"by faith alone." This did not mean that faith exists alone, as though saving faith produces no fruit. On the contrary, genuine faith always expresses itself in love and obedience (Galatians 5:6). What sola fide means is that faith is the only means by which we receive the benefits of Christ's atoning work. We are not justified by faith plus works, or faith plus baptism, or faith plus anything else. We are justified by grace through faith—and even faith itself is a gift of God (Ephesians 2:8–9). The entire transaction, from beginning to end, is of grace. Human beings contribute nothing but the sin from which they need to be saved. This is not a cause for despair but for deep, abiding joy—because it means that our standing before God does not depend on the quality of our performance but on the sufficiency of Christ's sacrifice.

I find it helpful to think of faith in terms of three dimensions that theologians have traditionally identified. There is notitia—knowledge of the facts of the gospel (that Christ died for sins, was buried, and rose again). There is assensus—mental agreement that these facts are true. And there is fiducia—personal trust, the actual resting of one's soul upon Christ for salvation. It is this third element—fiducia, personal trust—that is the heart of saving faith. A person can know the facts of the gospel and even agree that they are true without ever personally trusting Christ. But when knowledge and assent give way to trust—when a person stops merely believing about Christ and begins believing in Christ—that is the moment when the benefits of the atonement are appropriated and all the riches of justification, reconciliation, redemption, adoption, and sanctification become theirs.³⁸

As we discussed in Chapter 29, faith is the means by which we are united to Christ—and it is in that union that all the benefits of His death become ours. When Paul says we are justified "in Christ" (Galatians 2:17) or redeemed "in him" (Ephesians 1:7), he is pointing to the reality that our salvation is bound up with our relationship to the Savior. We are not saved by a transaction that happens at a distance. We are saved by being incorporated into Christ by faith—so that His death becomes our death, His resurrection becomes our resurrection, and His righteous standing before the Father becomes our righteous standing.

This is why the gospel is, at its core, an invitation. "Be reconciled to God," Paul urges (2 Corinthians 5:20). God has done everything necessary to deal with the problem of sin. Christ has borne the penalty. The ransom has been paid. The way home has been opened. But the invitation must be accepted. The gift must be received. And the means of receiving it is faith—the trusting, grateful, surrendered response of a human heart to the overwhelming love of God displayed at the cross.

Conclusion: The Riches of the Cross

We set out in this chapter to explore the benefits that flow from the cross to those who trust in Christ. What we have found is a staggering abundance—a wealth of saving blessings that no single image or metaphor can capture. Justification gives us a new standing before God. Reconciliation gives us a new relationship with God. Redemption gives us freedom from bondage. Propitiation assures us that divine justice has been satisfied. Adoption gives us a new identity as children of God. Sanctification transforms us into Christ's likeness. New creation means that everything is being made new.

Each of these benefits is distinct, yet they are deeply interwoven. You cannot have reconciliation without justification—the legal barrier must be removed before the relationship can be restored. You cannot have adoption without redemption—the slave must be set free before becoming a son. You cannot have sanctification without propitiation—the holy God can only transform those who have first been made right with Him through the atoning sacrifice of Christ. All the threads lead back to the cross, and at the cross, they all converge on the central reality of substitution: Christ in our place, bearing what we deserved, so that we might receive what He deserved.

David Allen summarizes it well: the atonement specifically addresses the means of salvation, while salvation covers the actual results of the atonement when applied to the believer. Atonement is the basis; salvation is the superstructure built upon it. And the heart of that atoning basis is substitution—the self-giving love of the Triune God who, in the Person of the Son, bore the consequences of human sin so that sinners might be justified, reconciled, redeemed, adopted, sanctified, and made new.³²

The Puritan Thomas Goodwin once compared the Christian to a person standing at the bottom of a mine, looking up through the shaft at a single circle of sky. That circle is real, but it is only a tiny glimpse of the vast expanse above. So it is with the benefits of the cross. What we have surveyed in this chapter is real—gloriously, transformatively real. But it is only a glimpse. The full reality of what Christ accomplished on the cross is deeper than our deepest theology, wider than our widest vision, and richer than our richest language can express. We will spend eternity exploring it and never reach the end.

As Stott beautifully observes: "Beyond the images of the atonement lies the mystery of the atonement, the deep wonders of which, I guess, we shall be exploring throughout eternity."³³ Until that day, we cling by faith to the One who died in our place, who bears us in His heart, and who has opened for us the way home to the Father. And we rejoice that the cross is not merely a doctrine to be studied but a love to be received—a love that justifies, reconciles, redeems, adopts, sanctifies, and makes all things new.
