Chapter 37

The Atonement, Worship, and the Christian Life

There is a danger in any book on the atonement. The danger is that we treat the cross of Jesus Christ as a problem to be solved—a puzzle for theologians and philosophers to work out on a whiteboard—rather than a reality that reshapes everything about how we live. I want to be clear at the outset of this chapter: the atonement is not simply a doctrine to be believed. It is a world-changing event that transforms every corner of the Christian life. It changes how we worship. It changes how we pray. It changes how we treat the people around us. It changes how we face suffering, how we pursue justice, and how we understand who we are.

Throughout this book, we have been building a careful case. We have examined the biblical evidence for penal substitutionary atonement (Chapters 4–12). We have traced the historical development of atonement theology through the centuries (Chapters 13–18). We have argued that PSA stands at the center of a multi-faceted understanding of the cross (Chapters 19–24). We have offered a philosophical defense of its coherence (Chapters 25–29). We have defended the universal scope of the atonement (Chapters 30–31) and answered a wide range of objections (Chapters 32–35). In the previous chapter, we explored the application of the atonement in justification, reconciliation, and redemption (Chapter 36).

Now we turn to what may be the most personal chapter in this entire book. What does the cross mean for everyday life? How should the atoning work of Christ shape the way we gather for worship on Sunday morning, the way we speak to our family members on Monday evening, and the way we respond to a broken and hurting world on every day in between?

The thesis of this chapter is straightforward: the atonement is not merely a doctrine to be believed but a reality that transforms every dimension of the Christian life—shaping how we worship, how we pray, how we treat one another, how we face suffering, and how we engage the world with the self-giving love of the cross. Doctrine and life are not two separate compartments. What we believe about the cross determines how we live under it.

I. The Cross at the Heart of Worship

If you want to know what really matters to a community, look at what they celebrate. Look at what they sing about. Look at the meal they share together. For the Christian church, the answer is unmistakable: the cross stands at the very center of our worship. From the earliest days of the church to the present moment, Christians have gathered to remember, proclaim, and celebrate the death of Jesus Christ for sinners.

The Lord's Supper: Proclaiming His Death Until He Comes

Consider the Lord's Supper—also called the Eucharist (from the Greek eucharistia [εὐχαριστία], meaning "thanksgiving"), Holy Communion, or the Lord's Table. Jesus Himself established this meal on the night before His crucifixion. He took bread, broke it, and said, "This is my body, which is given for you. Do this in remembrance of me." He took the cup and said, "This cup that is poured out for you is the new covenant in my blood" (Luke 22:19–20, ESV). Every time the church gathers around bread and wine, we are brought back to Calvary. The broken bread tells us that His body was broken for us. The poured-out cup tells us that His blood was shed for us.

The apostle Paul spells out the significance of this meal in unmistakable terms:

"For as often as you eat this bread and drink the cup, you proclaim the Lord's death until he comes." (1 Corinthians 11:26, ESV)

Notice what Paul says. The Lord's Supper is a proclamation. It is not merely a private devotional exercise. Every time the church celebrates Communion, it is making a public announcement to the world: Jesus Christ died for sinners, and He is coming back. The Lord's Supper looks backward to the cross and forward to Christ's return. It spans the entire period between His first coming and His second, serving as a continual reminder that the work accomplished at Calvary is the foundation of everything we are and everything we hope for.¹

As John Stott beautifully observed, the Lord's Supper is related to Christ's sacrifice on the cross in at least five ways. First, we remember His sacrifice—Jesus said, "Do this in remembrance of me." The prescribed actions with the bread and wine make the remembrance vivid and dramatic. Second, we partake of its benefits. Paul asks, "Is not the cup of thanksgiving for which we give thanks a participation in the blood of Christ? And is not the bread that we break a participation in the body of Christ?" (1 Corinthians 10:16). Third, we proclaim His sacrifice—"you proclaim the Lord's death until he comes." Fourth, we attribute our unity to His sacrifice: "Because there is one loaf, we, who are many, are one body, for we all partake of the one loaf" (1 Corinthians 10:17). Fifth, we give thanks for His sacrifice, and in response we offer ourselves as "living sacrifices" to His service (Romans 12:1).²

There is something deeply important here for our understanding of penal substitutionary atonement. When Jesus said, "This is my blood of the covenant, which is poured out for many for the forgiveness of sins" (Matthew 26:28), He was using explicitly sacrificial and substitutionary language. The blood is poured out—a clear echo of the Old Testament sacrificial system (as we explored in Chapters 4–5). It is poured out for many—that is, on behalf of others, in their place. And it is poured out for the forgiveness of sins—directly connecting the shedding of blood with the removal of the penalty that sin deserves. The Lord's Supper is not a general celebration of God's goodness. It is a specific, focused celebration of the fact that Jesus bore the consequences of our sin in our place so that we could be forgiven.

Paul also connects the Lord's Supper to the Passover, and this connection is deeply significant. He writes, "Christ, our Passover lamb, has been sacrificed. Therefore let us keep the Festival" (1 Corinthians 5:7, ESV). In the original Passover, a lamb was slain and its blood was applied to the doorframes of the Israelites' homes so that the angel of death would pass over them. As we argued in Chapter 4, the Passover was not simply deliverance from the Egyptians—it was deliverance from the judgment of God Himself. The lamb died so that the firstborn would not. That is penal substitution in its most dramatic Old Testament form. And Paul says that Jesus is our Passover Lamb. Because He has been sacrificed—because He bore the penalty that was due to us—the whole Christian life is to be one unending festival of celebration.³

Stott put it memorably: because Christ our Passover Lamb has been slain, and because by the shedding of His precious lifeblood we have been set free, the whole life of the Christian community should be understood as a festival in which we celebrate with love, joy, and boldness what God has done for us through Christ.⁴

Heavenly Worship: The Lamb Who Was Slain

The book of Revelation pulls back the curtain on the worship of heaven, and what we find there confirms that the cross is at the center of all worship—not just earthly worship but the eternal worship of the heavenly hosts. In Revelation 5, the apostle John sees a scroll sealed with seven seals, and no one in all of creation is found worthy to open it. John begins to weep. But then one of the elders says to him, "Weep no more; behold, the Lion of the tribe of Judah, the Root of David, has conquered, so that he can open the scroll and its seven seals" (Revelation 5:5, ESV).

What happens next is stunning. John turns to see this conquering Lion—and instead of a powerful beast he sees a Lamb "standing, as though it had been slain" (Revelation 5:6). The Lion of Judah conquers as the slain Lamb. Victory and sacrifice are fused together. And immediately, the heavenly chorus breaks out in worship:

"Worthy are you to take the scroll and to open its seals, for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation, and you have made them a kingdom and priests to our God, and they shall reign on the earth." (Revelation 5:9–10, ESV)

Then the circle of worship widens. Myriads of angels join in, singing, "Worthy is the Lamb who was slain, to receive power and wealth and wisdom and might and honor and glory and blessing!" (Revelation 5:12). And then every creature in heaven and on earth and under the earth and in the sea—the entire created order—joins in: "To him who sits on the throne and to the Lamb be blessing and honor and glory and might forever and ever!" (Revelation 5:13).

This is the ultimate picture of worship. And notice what stands at the center of it: the Lamb who was slain. Not merely the Lamb who lived a good life. Not merely the Lamb who taught beautiful truths. The Lamb who was slain—who shed His blood to ransom people for God. The cross is not a temporary focus of worship that we will outgrow when we get to heaven. The cross is the eternal center of the worship of the universe.⁵

The Singing Church: Hymns of the Cross

There is something Christians do that no other religious community does in quite the same way: we sing. We sing with joy, with passion, with gratitude. And overwhelmingly, we sing about the cross. Think of the great hymns of the faith: "When I Survey the Wondrous Cross," "Amazing Grace," "And Can It Be That I Should Gain," "The Old Rugged Cross," "In Christ Alone." The cross is woven into the fabric of Christian song from the earliest centuries to the latest worship album.

Stott drew attention to a fascinating observation by W. M. Clow: the uniqueness of Christian singing is directly connected to the reality of forgiveness through the cross. The great faiths of Buddhism and Islam give little or no place to the concept of divine forgiveness. A Buddhist temple does not resound with cries of praise. Muslim worship, at its highest, consists of prayers of submission and petition, but rarely reaches the note of thanksgiving. Christian worship, by contrast, is characterized by irrepressible singing—the songs of the forgiven.⁶

Why do Christians sing? Because we have been forgiven at unimaginable cost. Because the penalty for our sin has been borne by Another. Because we who were dead in our trespasses have been made alive. Because the Lamb was slain and by His blood we have been ransomed. We sing because we cannot help it. Joy demands expression, and the joy of the redeemed demands song.

This is worth pausing over. A merely subjective or moral-influence understanding of the atonement—one that sees the cross only as a moving example of self-sacrifice—might produce admiration, but it is hard to see how it would produce the explosive, centuries-long tradition of rapturous Christian song. It is the objective reality of penal substitution—the fact that Christ actually bore the penalty for our sin and we are genuinely forgiven—that generates the kind of joy that cannot be contained. The doctrine of the atonement is not just an abstract theological idea. It is the engine of Christian worship.

The Eastern Tradition: The Cross in Orthodox Worship

We should note here that the connection between the cross and worship is not unique to Western Christianity. The Eastern Orthodox tradition, with its rich liturgical life, is also saturated with the language of Christ's atoning sacrifice. As Fr. Joshua Schooping has demonstrated, Orthodox hymnography (that is, the hymns and prayers of the Orthodox Church) is permeated with penal and substitutionary language. Orthodox worship speaks repeatedly of Christ bearing our sins, suffering our penalty, and offering Himself as a sacrifice to the Father on our behalf.⁷

Schooping has shown, drawing on sources such as Patriarch Jeremiah II, Patriarch Dositheus, and Peter Mogila, that the Eucharist in the Orthodox tradition is understood in explicitly sacrificial terms that presuppose a penal substitutionary framework. The Confession of Dositheus (1672) affirms that Christ is "advocate and propitiation for our sins" who "through His own Blood made a reconciliation between God and man." Mogila speaks of the Eucharist as "a Propitiation, or Atonement with God, for our Sins" and connects it directly to the fact that Christ "was wounded for our transgressions" and "bruised for our iniquities" (Isaiah 53:4–5).⁸ The cross is not a Western addition to Christian worship. It is the common inheritance of the entire church, East and West alike.

II. The Atonement and Gratitude: Living Sacrifices

If worship is the most visible expression of the cross-shaped life, gratitude is the deep wellspring from which it flows. One of the most important passages in all of Paul's letters is Romans 12:1–2, and understanding how this passage functions in the argument of Romans is crucial:

"I appeal to you therefore, brothers, by the mercies of God, to present your bodies as a living sacrifice, holy and acceptable to God, which is your spiritual worship. Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect." (Romans 12:1–2, ESV)

That little word "therefore" is doing enormous work. Paul has just spent eleven chapters laying out the most comprehensive theological argument in all of Scripture. He has explained the universality of human sin (Romans 1–3), the reality of justification by faith through the atoning work of Christ (Romans 3:21–5:21), our union with Christ in His death and resurrection (Romans 6–8), and God's sovereign purposes for Israel and the nations (Romans 9–11). All of this—the whole breathtaking sweep of God's plan of salvation, centered on the cross—is summed up in the phrase "the mercies of God."

And what is the appropriate response to these mercies? Not a feeling. Not a warm glow of spiritual satisfaction. The response is the offering of our entire selves—our bodies, Paul says, meaning our whole lived existence in the physical world—as "a living sacrifice." The sacrifice language is deliberate. Just as Christ offered Himself as a sacrifice for us (as we explored in Chapters 4–10), we now offer ourselves in return. But our sacrifice is fundamentally different from His. His was a propitiatory sacrifice—a sacrifice that bore the penalty of sin and turned away God's just judgment (as argued in Chapters 8 and 19). Ours is a eucharistic sacrifice—a sacrifice of thanksgiving, offered not to earn God's favor but in grateful response to the favor we have already received.⁹

This distinction, which the Reformers labored to make clear, is absolutely vital. As Thomas Cranmer argued in the sixteenth century, there are two kinds of sacrifice. The first is the "propitiatory or merciful sacrifice"—a sacrifice that satisfies God's justice and obtains mercy and forgiveness for sin. There has only ever been one such sacrifice: the death of Christ on the cross. The second is the sacrifice of "laud, praise and thanksgiving," offered not to reconcile us to God but by those who have already been reconciled, as a way of expressing gratitude and devotion. Christ offered the first kind of sacrifice for us. We offer the second kind through Him.¹⁰

The implications of this are profound. The Christian life is not fundamentally about earning, achieving, or performing. It is about receiving and responding. We do not serve God in order to make ourselves acceptable to Him. We serve God because He has already made us acceptable through the blood of His Son. Our obedience flows from gratitude, not from fear. Our good works are the fruit of grace, not the root of it.

Jeffery, Ovey, and Sach put it well: the dynamic relationship between understanding and action lies at the heart of the Christian life. Doctrine is for life and godliness, not for ivory-tower speculation. A correct understanding of what Christ has done for us is the foundation, but it is only the beginning. From that foundation flows a transformed life of grateful obedience.¹¹

Stott, in cataloguing the "spiritual sacrifices" that the New Testament calls us to offer, identified eight distinct offerings: (1) the presentation of our bodies as living sacrifices (Romans 12:1); (2) our praise, worship, and thanksgiving (Hebrews 13:15); (3) our prayers, rising to God like fragrant incense (Revelation 5:8); (4) a broken and contrite heart (Psalm 51:17); (5) our faith (Philippians 2:17); (6) our gifts and good deeds (Hebrews 13:16); (7) our lives poured out in service even to the point of death (2 Timothy 4:6); and (8) the evangelist's offering of new converts to God (Romans 15:16). All of these are "true and evangelical sacrifices," because they belong to the gospel, not the law, and are thankful responses to God's grace in Christ.¹²

III. The Atonement and Self-Giving Love

The cross is not only the ground of our worship and the source of our gratitude. It is also the pattern for our love. One of the most striking features of the New Testament's ethical teaching is that it roots the call to love others directly in the love that Christ demonstrated at the cross.

The apostle John makes this connection with breathtaking clarity:

"By this we know love, that he laid down his life for us, and we ought to lay down our lives for the brothers." (1 John 3:16, ESV)

Notice the logic here. How do we know what love is? Not from Hollywood movies. Not from romantic poetry. Not from our own feelings or instincts. We know what love is because Christ laid down His life for us. The cross is the definition of love. And if that is what love looks like, then the call on our lives is clear: "we ought to lay down our lives for the brothers." The same self-giving, self-sacrificing, other-oriented pattern of love that Christ demonstrated at Calvary is the pattern we are called to follow in our daily lives.

Paul makes the same point in Ephesians 5:

"Therefore be imitators of God, as beloved children. And walk in love, as Christ loved us and gave himself up for us, a fragrant offering and sacrifice to God." (Ephesians 5:1–2, ESV)

The language here is richly sacrificial. Christ "gave himself up for us"—He offered Himself in our place, bearing the consequences of our sin. And His self-offering was "a fragrant offering and sacrifice to God"—language drawn directly from the Old Testament sacrificial system (see Leviticus 1:9, 13). Our calling is to "walk in love" in the same way that Christ loved us. His sacrificial, substitutionary love is the model for our own self-giving.

I want to be clear about something here. When the New Testament says we should love "as Christ loved us," it does not mean we should try to atone for other people's sins. Only Christ can do that. His sacrifice was unique and unrepeatable—He alone could bear the penalty of sin as the sinless Son of God (as argued in Chapters 19–20). But the pattern of His love—its other-directedness, its willingness to absorb cost and pain for the sake of the beloved, its refusal to insist on its own rights—that pattern is one we are called to imitate.¹³

What does this look like in practice? It looks like a parent who sacrifices sleep, comfort, and personal ambition for the sake of a child. It looks like a friend who absorbs an insult rather than retaliating. It looks like a church member who gives generously to those in need even when money is tight. It looks like a missionary who leaves home and family to bring the gospel to people who have never heard it. It looks like a spouse who chooses to serve rather than to be served. In all of these ways and a thousand more, the cross-shaped love of Christ is lived out in the everyday stuff of human relationships.

The Orthodox tradition has a beautiful way of expressing this. Fr. Joshua Schooping has shown that in Orthodox theology, the atoning work of Christ is not something that remains "outside" the believer. It becomes the interior reality of the Christian life through what the Fathers call theosis (θέωσις)—the process by which believers are progressively transformed into the likeness of Christ. The cross, in this framework, is not merely a legal transaction that happened two thousand years ago. It is a living reality that shapes the believer's heart, mind, and behavior from the inside out. Penal substitutionary atonement and the life of transformation in Christ are, as Schooping puts it, "two halves of a single piece."¹⁴ The objective work of Christ on the cross becomes subjectively real in the believer through the ongoing work of the Holy Spirit.

IV. The Atonement and the Forgiveness of Others

Few areas of the Christian life are more difficult—and more directly shaped by the cross—than the call to forgive others. The apostle Paul writes:

"Put on then, as God's chosen ones, holy and beloved, compassionate hearts, kindness, humility, meekness, and patience, bearing with one another and, if one has a complaint against another, forgiving each other; as the Lord has forgiven you, so you also must forgive." (Colossians 3:12–13, ESV)

The logic is powerful and inescapable. As the Lord has forgiven you, so you must forgive. The measure of our forgiveness of others is nothing less than the forgiveness we have received from God in Christ. And what kind of forgiveness is that? It is a forgiveness that cost the blood of the Son of God. It is a forgiveness extended to people who had done nothing to deserve it—who were, in fact, actively hostile to the One who forgave them. It is a forgiveness grounded in the reality of penal substitution: Christ bore the penalty for our sins so that we could be freely and fully pardoned.

If God was willing to bear such an unimaginable cost to forgive us, how can we refuse to forgive the comparatively small offenses committed against us by others? Jesus made this point in His parable of the unforgiving servant (Matthew 18:21–35). A servant owed his master an astronomical debt—ten thousand talents, an amount so large it could never be repaid in a hundred lifetimes. The master graciously canceled the debt. But that same servant went out and seized a fellow servant who owed him a mere hundred denarii—a trivial amount by comparison—and had him thrown into prison. When the master heard about it, he was furious: "Should not you have had mercy on your fellow servant, as I had mercy on you?" (Matthew 18:33).

The parable is devastating in its clarity. Every sin committed against us by other human beings—however painful and however real—is like a hundred denarii compared to the ten-thousand-talent debt we owed to God. And that debt has been paid. Not by us, but by Christ, on the cross. We who have been forgiven so much dare not withhold forgiveness from others.¹⁵

Now, I want to be careful here, because the topic of forgiveness can be deeply painful and easily misunderstood. Forgiveness does not mean pretending that a wrong was not committed. It does not mean that consequences disappear or that trust is automatically restored. Forgiveness is not the same as reconciliation, which often requires repentance on the part of the offender and a process of rebuilding trust over time. And forgiveness certainly does not mean that victims of abuse or injustice should simply "get over it" or return to a dangerous situation. The cross itself teaches us that God takes sin with absolute seriousness—He did not simply wave it away but bore its full consequences in the person of His Son. But forgiveness does mean releasing the debt, refusing to hold the offense against the other person, and choosing not to seek revenge. It means entrusting justice to God rather than taking it into our own hands (Romans 12:19).

There is a real sense in which the practice of forgiveness is one of the most powerful testimonies to the reality of the cross in the world today. When a person who has been deeply wronged chooses to forgive—not because the offense was trivial, not because justice does not matter, but because they themselves have been forgiven at the cross—it makes the gospel visible. It shows a watching world what it looks like when the love of the crucified Christ takes hold of a human heart and transforms it. Nothing in human nature inclines us to forgive deep wounds. It is only the grace that flows from Calvary that makes such forgiveness possible.

The apostle Paul's own life demonstrates this. He had been a violent persecutor of the church—"a blasphemer, persecutor, and insolent opponent" of Christ (1 Timothy 1:13). He had overseen the imprisonment and execution of Christians. And yet he received mercy. The risen Christ met him on the Damascus road and transformed him from the church's fiercest enemy into its most tireless advocate. Paul's entire ministry was fueled by the awareness that he had been forgiven an incalculable debt. He wrote, "The saying is trustworthy and deserving of full acceptance, that Christ Jesus came into the world to save sinners, of whom I am the foremost" (1 Timothy 1:15). That awareness of having been forgiven made Paul a man who extended grace freely to others—even to those who opposed and mistreated him.

The connection to penal substitution is direct and vital. Because we believe that Christ actually bore the penalty for sin—that real justice was accomplished at the cross—we are freed from the desperate need to exact justice ourselves. We can forgive without fearing that sin has gone unpunished, because we know that it has been dealt with at the cross. As Jeffery, Ovey, and Sach observe, penal substitution undergirds our capacity for forgiveness precisely because it assures us that God's justice has not been compromised. Sin has been paid for. The penalty has been borne. And so we are free to extend mercy, just as mercy has been extended to us.¹⁶

V. The Atonement and Suffering

The problem of suffering is one of the deepest questions any human being faces. Why does God allow it? What purpose does it serve? How should we respond when it comes? The cross of Christ does not answer every question about suffering—there remains genuine mystery—but it does provide a framework for understanding that suffering endured in faithfulness to Christ has meaning and value.

The apostle Peter writes:

"For to this you have been called, because Christ also suffered for you, leaving you an example, so that you might follow in his steps. He committed no sin, neither was deceit found in his mouth. When he was reviled, he did not revile in return; when he suffered, he did not threaten, but continued entrusting himself to him who judges justly. He himself bore our sins in his body on the tree, that we might die to sin and live to righteousness. By his wounds you have been healed." (1 Peter 2:21–24, ESV)

This passage holds together the two dimensions of the cross that we have been tracing throughout this book. On one hand, the cross is a substitutionary sacrifice: "He himself bore our sins in his body on the tree." This is something Christ did that we can never do—He bore the penalty of sin in our place (as argued in detail in Chapter 11). On the other hand, the cross is an example: "Christ also suffered for you, leaving you an example, so that you might follow in his steps." This is something we are called to imitate—a pattern of patient endurance, trust in God, and refusal to retaliate in the face of unjust suffering.¹⁷

I believe it is critical to hold both dimensions together. If we emphasize the example without the substitution, we end up with a merely moral-influence view of the cross that provides inspiration but not salvation. If we emphasize the substitution without the example, we end up with a cross that saves our souls but has no bearing on how we live. The New Testament gives us both. Christ died for us (substitution) and Christ died as an example for us (moral pattern). The substitution makes the example possible, because it is only as forgiven sinners—people who have been set free from the penalty of sin—that we can even begin to follow in the footsteps of a sinless Savior.

The cross teaches us several things about suffering. First, it tells us that God is not distant from our pain. The God we worship is not a detached deity watching human misery from a comfortable distance. He is a God who entered into the deepest depths of human suffering—who was "despised and rejected by men, a man of sorrows and acquainted with grief" (Isaiah 53:3). Whatever we suffer, we serve a Savior who has suffered more.

Second, the cross tells us that suffering can be redemptive. Not all suffering is redemptive, of course—much suffering in this world is simply the result of sin and injustice and the brokenness of a fallen creation. But the cross teaches us that God is able to bring good out of even the worst evil. The most horrific act of injustice in human history—the crucifixion of the sinless Son of God—became the means of the world's salvation. If God can bring such good out of such evil, then we can trust that He is able to work in and through our suffering as well, even when we cannot see how.

Third, the cross gives us a model for how to suffer well. Jesus did not retaliate. He did not curse His tormentors. He entrusted Himself to the Father who judges justly. He absorbed the evil directed at Him rather than multiplying it by striking back. This is the pattern Peter holds up for us: when we suffer unjustly, we are called to follow Christ's example by responding with patience, trust, and an unwillingness to return evil for evil.

Paul expresses the same idea in a deeply personal way. He writes of his desire to know Christ—"that I may know him and the power of his resurrection, and may share his sufferings, becoming like him in his death" (Philippians 3:10). For Paul, sharing in Christ's sufferings is not something to be avoided but something to be embraced, because it is the path to deeper intimacy with Christ and a greater experience of the power of His resurrection.¹⁸

This is a staggering statement when you stop to think about it. Paul is not talking about mild inconvenience. He is talking about real suffering—the kind of suffering he catalogued in 2 Corinthians 11:23–28: beatings, imprisonments, shipwrecks, hunger, exposure, the daily pressure of anxiety for all the churches. Yet Paul sees all of this as a privilege because it connects him more deeply to Christ. The cross is not merely a doctrine Paul affirms intellectually. It is a reality he inhabits existentially. His suffering becomes a participation in the suffering of the One who bore the sins of the world.

And Paul is not unique in this. Throughout the history of the church, Christians who have suffered most deeply have often testified most powerfully to the sustaining reality of the cross. The martyrs of the early church went to their deaths singing hymns. Dietrich Bonhoeffer, awaiting execution in a Nazi prison, wrote of "the cost of discipleship" and found in the cross both the meaning of his suffering and the strength to endure it. Corrie ten Boom, who survived the horrors of Ravensbrück concentration camp, testified that "there is no pit so deep that God's love is not deeper still"—and she traced that love directly to the cross. These are not people who found the atonement to be an abstract theological idea disconnected from real life. They found it to be the most real thing in the universe—the one solid ground on which they could stand when everything else was stripped away.

Stott's treatment of suffering and the cross in The Cross of Christ is especially helpful here. He recognized that the call to take up our cross and follow Jesus (Mark 8:34) is a call to self-denial—not the trivial self-denial of giving up chocolate during Lent, but the fundamental self-denial of putting Christ's purposes ahead of our own comfort, security, and even survival. Every Christian is both a Barabbas and a Simon of Cyrene. Like Barabbas, we escape the cross because Christ died in our place. Like Simon of Cyrene, we carry the cross because Christ calls us to take it up and follow Him.¹⁹

VI. The Atonement and Justice

The cross of Christ has everything to do with justice. This is one of the most important practical implications of penal substitutionary atonement, and it is one that is sometimes missed or underemphasized.

Consider what the cross reveals about God's attitude toward evil. As we argued in Chapter 3, God's wrath against sin is not irrational anger or vindictive rage. It is the settled, just, holy opposition of God's perfect nature to everything that is evil, destructive, and dehumanizing. God hates sin because He loves what is good. He opposes injustice because He is committed to the flourishing of His creatures. The cross is the ultimate demonstration that God does not ignore sin, does not minimize its seriousness, and does not leave it unpunished. At the cross, the full weight of God's just response to evil was borne by Christ, who stood in our place.

But if God is so passionately committed to justice that He would go to the cross to deal with sin, then His people should be passionately committed to justice as well. Because the cross reveals God's hatred of sin and His love for the oppressed, Christians are called to pursue justice in the world—opposing evil, defending the vulnerable, and working for the flourishing of all people.²⁰

The prophets of Israel made this connection repeatedly. Isaiah thundered against those who "deprive the poor of their rights and withhold justice from the oppressed of my people, making widows their prey and robbing the fatherless" (Isaiah 10:2). Amos proclaimed, "But let justice roll on like a river, righteousness like a never-failing stream!" (Amos 5:24). Micah declared, "He has shown you, O mortal, what is good. And what does the LORD require of you? To act justly and to love mercy and to walk humbly with your God" (Micah 6:8). The God who acts justly at the cross calls His people to act justly in the world.

Some critics of penal substitution have argued that the doctrine is disconnected from social ethics—that it deals only with individual guilt before God and has nothing to say about systemic injustice, racial reconciliation, or the plight of the poor. As Jeffery, Ovey, and Sach have pointed out, this criticism is unfounded. Penal substitution does not promote individualism; it actually undermines it, because the justice of penal substitution is founded on our union with Christ—which means we have been brought into a community, the body of Christ, where barriers of race, class, and nationality are broken down (Galatians 3:28). Moreover, those who are transformed by the gospel of penal substitution—those who have been forgiven, set free, and filled with gratitude—are precisely the people who should be most motivated to seek justice for others.²¹

John Stott is a powerful example of this. He was one of the twentieth century's foremost defenders of penal substitutionary atonement, and he was simultaneously one of the most vigorous advocates for social justice in the evangelical world. He founded the London Institute for Contemporary Christianity and was instrumental in the Lausanne Congress on World Evangelization's affirmation that "evangelism and socio-political involvement are both part of our Christian duty." For Stott, the cross was not a doctrine that pulled him away from engagement with the world's problems. It was the very thing that drove him toward it.²²

The cross teaches us that justice matters to God. It teaches us that sin—including the sin of oppression, exploitation, and neglect of the vulnerable—is something God takes with ultimate seriousness. And it teaches us that the proper response to receiving mercy is to show mercy to others. Christians who understand the cross should be at the forefront of every effort to bring justice, healing, and hope to a broken world.

VII. The Atonement and Self-Understanding

The cross also transforms how we understand ourselves. In a world that oscillates between crippling self-hatred on one hand and narcissistic self-worship on the other, the cross offers a radical alternative. It tells us the truth about ourselves—both the hard truth and the wonderful truth—and it holds the two together in a way that produces genuine humility and genuine confidence at the same time.

As Stott observed, the cross simultaneously calls us to self-denial and self-affirmation. The hard truth is that we are sinners. The cross tells us that our sin was so serious that nothing less than the death of the Son of God could deal with it. We cannot save ourselves. We are not basically good people who just need a little help. We are rebels against the God who made us, and our rebellion has brought death and destruction into the world. The cross strips away every illusion of self-sufficiency and self-righteousness.²³

But the wonderful truth is that we are infinitely valued. The very same cross that exposes the depth of our sin reveals the depth of God's love for us. If God was willing to give His only Son to die for us, then we are worth more than we could ever imagine. Our value is not based on our performance, our appearance, our achievements, or our social status. Our value is based on the price God paid for us—and that price was the blood of His Son.

This produces a unique kind of identity. We are simultaneously humbled and exalted. We are humbled because we know we are sinners who deserve judgment. We are exalted because we know we are sinners whom God loved so much that He bore that judgment Himself. This is what Paul means when he says we should "think of ourselves with sober judgment" (Romans 12:3, ESV). The cross prevents both self-hatred (because it tells us how much God values us) and self-worship (because it tells us how much our sin cost).

Paul's teaching on our union with Christ is central here (see Chapter 28). Because we are "in Christ," we have died with Him and been raised with Him to new life (Romans 6:3–11). The old self—the person we were in Adam, defined by sin and subject to condemnation—has been crucified with Christ. A new self has emerged—defined by grace, clothed in Christ's righteousness, and destined for glory. This is not wishful thinking. It is an accomplished fact, based on the objective reality of what Christ did on the cross. And it is this fact that we are called to "reckon" or "count" as true in our daily lives (Romans 6:11).²⁴

VIII. The Atonement and Prayer

The cross also transforms our prayer life in profound ways. Because of what Christ accomplished at Calvary, we have been given something the Old Testament saints could scarcely have imagined: direct, personal, bold access to the presence of the living God.

The author of Hebrews makes this 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, and since we have a great priest over the house of God, let us draw near with a true heart in full assurance of faith, with our hearts sprinkled clean from an evil conscience and our bodies washed with pure water." (Hebrews 10:19–22, ESV)

The word translated "confidence" is the Greek parrēsia (παρρησία), which means "boldness, frankness, freedom of speech." It conveys the idea of open, unhindered access. And notice the basis for this boldness: it is "by the blood of Jesus." We do not enter God's presence on the basis of our own worthiness. We enter on the basis of Christ's atoning sacrifice. His blood has cleansed our consciences and opened a "new and living way" into the very presence of God.²⁵

Under the Old Covenant, only the high priest could enter the Most Holy Place, and he could do so only once a year, on the Day of Atonement, and only with the blood of a sacrifice (as we explored in Chapter 5). But now, because Christ our great High Priest has offered the perfect, once-for-all sacrifice of Himself, every believer has the right and the privilege of entering God's presence freely and boldly at any time. Prayer is not a matter of trying to get God's attention or of hoping that we might be worthy enough to be heard. It is the joyful exercise of a privilege that has been purchased for us at the cost of Christ's blood.

The Eastern Orthodox tradition of the Jesus Prayer ("Lord Jesus Christ, Son of God, have mercy on me, a sinner") captures this dynamic beautifully. As Schooping has shown, the Jesus Prayer is deeply connected to the reality of penal substitutionary atonement. It is a prayer of humility, acknowledging our sinfulness and our need for mercy. But it is also a prayer of confidence, because it is addressed to the One who has already accomplished our salvation through His atoning death. The Jesus Prayer expresses the highest virtue of humility and dependence on Christ's saving work.²⁶

IX. The Atonement and the Community of the Cross

Finally, the cross creates a community. The atonement is not merely an individual transaction between God and the solitary sinner. It creates a new people—what Stott called "the community of the cross."²⁷

Paul makes this point in Titus 2:14: Christ "gave himself for us to redeem us from all lawlessness and to purify for himself a people for his own possession who are zealous for good works" (ESV). The purpose of Christ's self-giving on the cross was not just to save isolated individuals but to create a new community—a people who belong to Him, who love one another, and who are eager to serve the world.

This community is nothing less than a renewed and reunited humanity. In Ephesians 2, Paul describes how the cross has broken down the dividing wall of hostility between Jew and Gentile, creating "one new man in place of the two, so making peace" (Ephesians 2:15). The cross is the great equalizer: all of us come to it as sinners in need of grace, and all of us leave it as forgiven children of God. There is no room for racial pride, ethnic hostility, or class division at the foot of the cross. As Paul declares in Galatians 3:28, "There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus."

Think about what this means practically. When Christians gather for worship on Sunday morning, the billionaire sits next to the janitor. The immigrant sits next to the native-born citizen. The former addict sits next to the lifelong churchgoer. What unites them is not their social status, their education, their political opinions, or their cultural background. What unites them is the cross—the shared reality that every one of them is a sinner who has been forgiven at the cost of Christ's blood. This is the most radically egalitarian community in the world, because it is a community where the only credential for admission is need, and the only source of standing is grace.

The early church understood this intuitively. One of the most remarkable features of the first-century Christian community was its social diversity. Slaves and masters worshiped side by side. Jews and Gentiles broke bread together—something unthinkable in the ancient world. Rich and poor shared their resources with one another. And this social transformation was not incidental to the gospel. It was a direct consequence of it. Because Christ died for all, all who come to Christ are united to one another. The vertical reconciliation accomplished at the cross—between humanity and God—produces horizontal reconciliation between human beings who would otherwise have nothing in common.

The community of the cross is marked by distinctive characteristics that flow directly from the cross itself. It is a community of celebration, because we have been forgiven. It is a community of self-giving love, because Christ gave Himself for us. It is a community of forgiveness, because we have been forgiven at infinite cost. It is a community of justice, because the God who judges justly calls us to pursue justice in the world. It is a community of hope, because the same Christ who died for us is coming again to make all things new.

As Stott summarized it, the community of Christ is the community of the cross. Having been brought into being by the cross, it continues to live by and under the cross. Our perspective and our behavior are governed by the cross. All our relationships have been radically transformed by it. The cross is not just a badge to identify us and a banner under which we march; it is the compass that gives us our bearings in a disoriented world.²⁸

X. Answering the Objection: Is PSA Disconnected from Ethics?

Before we conclude, we need to address an important objection. Some critics have charged that penal substitutionary atonement is an "entirely objective" doctrine—a distant legal transaction that happened "out there" between God the Father and God the Son and has nothing to do with the way we live our daily lives. Joel Green and Mark Baker, for example, have argued that PSA "coheres so fully with the emphasis on autonomous individualism characteristic of so much of the modern middle class in the West" that it fails to address social and ethical concerns.²⁹ Colin Greene has suggested that in the penal substitutionary framework, "the act of atonement is so objectivized that it appears to be an event or transaction whereby we are simply removed from the scene."³⁰

I think this objection fundamentally misunderstands what penal substitution actually teaches. Let me offer three responses.

First, as Jeffery, Ovey, and Sach have pointed out, penal substitution is not proposed as the only biblical facet of the atonement, and certainly not as the only implication of the death of Christ. It is one part of an interconnected web of theological themes, and to criticize it for not saying everything there is to say is like criticizing an engine for not steering the car. Penal substitution is one piece of the puzzle—the central piece, I have argued throughout this book—but it connects to all the other pieces. Union with Christ, regeneration, redemption, the gift of the Holy Spirit, our adoption as God's children—all of these are closely connected to penal substitution and all of them have profound ethical implications.³¹

Second, penal substitution itself, rightly understood, undermines the individualism it is accused of promoting. As Garry Williams has shown, the justice of penal substitution depends on the union between Christ and His people. We are not autonomous individuals receiving a private benefit. We are members of a corporate body, united to our Head, who died for us and in whom we have died and been raised to new life. This is the opposite of individualism.³²

Third, and most important, the objective reality of penal substitution is precisely what makes the subjective transformation of the Christian life possible. It is because Christ bore the penalty for my sin that I am set free from guilt and shame. It is because I have been justified that I can face the future with confidence rather than fear. It is because I know that God's justice has been satisfied at the cross that I can forgive others without needing to exact revenge. It is because I have been loved at such infinite cost that I am motivated to love others in return. The objective and the subjective are not in competition. The objective is the foundation for the subjective. As Paul Fiddes acknowledged, proponents of penal substitution do not "add" a subjective dimension as if the two could exist separately; rather, they consider them intrinsically related from the beginning.³³

Schooping's work is especially illuminating here. He has demonstrated that in the Orthodox mystical tradition, penal substitutionary atonement and the transformative life in Christ are not two separate tracks running in opposite directions. They are interwoven at the deepest level. Christ bore the full weight of sin's consequences on the cross—the "tidal wave of sin-energy," as Schooping vividly puts it—so that in Him the energy of sin is neutralized, the curse undone, and the blessing restored. And it is precisely because this objective work has been accomplished that believers can experience the subjective transformation of theosis—the progressive indwelling of Christ's life and love in the human heart.³⁴

Conclusion

We have covered a lot of ground in this chapter, so let me draw the threads together.

The atonement is not a museum piece to be admired from a distance. It is a living reality that transforms everything it touches. The cross shapes our worship—it is the center of the Lord's Supper, the focus of heavenly adoration, and the engine of Christian song. The cross generates our gratitude—because of what Christ has done for us, we offer ourselves as living sacrifices in joyful response. The cross patterns our love—the self-giving, other-directed love of Calvary is the model for all Christian love. The cross empowers our forgiveness—because we have been forgiven at infinite cost, we extend forgiveness to others. The cross frames our suffering—Christ both bore our sins (substitution) and left us an example to follow (pattern). The cross fuels our pursuit of justice—because God takes sin and oppression with ultimate seriousness, so must we. The cross reshapes our identity—humbling us as sinners and exalting us as the beloved of God. The cross gives us boldness in prayer—we approach God's throne with confidence because Christ's blood has opened the way. And the cross creates a community—a people of celebration, forgiveness, love, and hope.

I want to close with a thought that has become increasingly important to me as I have worked on this book. There is a danger, especially in academic theology, of becoming so absorbed in debates about the atonement that we lose sight of the atonement itself. We can argue endlessly about models and metaphors, about propitiation versus expiation, about the precise nature of divine justice—and all of that matters, as I hope this book has shown. But the cross is ultimately not a problem to be solved. It is a love to be received and a life to be lived.

The great theologians of the church have always understood this. Anselm, for all the rigor of his argument in Cur Deus Homo, was first and foremost a man of prayer—his theology flowed from worship and returned to worship. Luther's rediscovery of justification by faith was not a dry academic exercise; it was a shattering personal encounter with the God who justifies the ungodly by the blood of His Son. Calvin, for all his reputation as a cold systematizer, wrote about the cross with deep warmth and personal devotion. And John Stott, whose work we have drawn on extensively in this chapter, once wrote that the cross of Christ is the blazing fire at which the flame of our love is kindled—but that we have to get near enough to it for its warmth to reach us.³⁵

That is the invitation that stands before us as we near the end of this book. Not merely to understand the atonement—though understanding matters enormously—but to be transformed by it. To let the reality of what Christ accomplished on the cross sink so deeply into our hearts that it changes everything about us: our worship, our relationships, our response to suffering, our pursuit of justice, our understanding of who we are, and our hope for the world.

The early Christians understood this. They did not merely believe in the cross. They lived under it. They sang about it. They celebrated it in the breaking of bread and the sharing of the cup. They loved one another because of it. They forgave one another because of it. They faced suffering and death because of it. And they went out into a broken, hostile world armed with nothing but the message of a crucified and risen Savior—and they turned that world upside down.

May we do the same. The Lamb who was slain is worthy of our worship, our gratitude, our love, our obedience, and our lives. Let us live accordingly.
