Chapter 3

The Character of God — Love, Justice, Holiness, and the Cross

Before we can understand what happened on the cross, we need to understand who was behind it. Everything we believe about the atonement flows from what we believe about God. If we get God wrong, we will get the cross wrong. It really is that simple.

Think of it this way. Imagine two people watching the same sunset. One believes the sun is a flaming chariot driven across the sky by a god. The other understands it as a star around which our planet orbits. They see the same sunset, but they understand it in completely different ways. Their background beliefs shape how they interpret what is right in front of them. The same is true of the cross. Two people can look at the crucifixion of Jesus and come away with radically different understandings of what happened—and the difference almost always traces back to what they believe about God.

This is why theology proper—the study of who God is—must come before soteriology—the study of how God saves. As John Stott wrote with great clarity, all wrong thinking about the atonement comes from wrong thinking about God and humanity. When our understanding of God's holiness and our sinfulness gets out of balance, our understanding of the cross will be out of balance too.¹ I believe Stott was exactly right. The cross only makes sense when we see it against the backdrop of who God truly is.

So in this chapter, I want to do something foundational. I want to walk us through what the Bible teaches about God's character—especially His love, His justice, His holiness, and His wrath—and show how these attributes come together at the cross. My thesis is straightforward: God's love, justice, and holiness are not competing attributes pulling in different directions. They are complementary perfections that together make the cross both necessary and beautiful. The atonement is not the story of an angry God being appeased by a reluctant Son. It is the story of a loving, holy, and just God who bears the cost of reconciliation Himself.

Theology Proper as the Foundation for Understanding the Cross

I cannot stress this enough: how we understand God determines how we understand the cross. This may sound obvious, but it is remarkable how often people jump straight into debating theories of the atonement without first asking, "What kind of God are we talking about?" The result is confusion, distortion, and sometimes real damage to the faith of ordinary believers.

Consider the different pictures that emerge depending on which attribute of God we emphasize. If we focus exclusively on God's love while ignoring His justice, we end up asking, "Why should our forgiveness depend on Christ's death? Why couldn't God just forgive everyone without the cross? Why all the bloodshed?" The cross looks unnecessary—even barbaric. On the other hand, if we focus exclusively on God's justice and wrath while ignoring His love, we end up with a terrifying picture of a God who is primarily angry, who demands blood before He will calm down. The cross becomes an act of violence inflicted by the Father on an unwilling Son. Both pictures are distortions. Both come from an unbalanced view of who God is.

The great Catholic Thomistic theologian Philippe de la Trinité identified this problem with surgical precision. He argued that the fundamental error in many distorted views of the atonement is the claim that Christ suffered on the cross to satisfy retributive justice—as though God the Father were enraged at His Son. Philippe insisted that this is false: it would be unjust and criminal to punish an innocent man instead of the guilty, and Jesus never bore the anger of God the Father.² Now, as we will see, I believe there is a real penal dimension to the atonement. But Philippe's critique of distorted portrayals is valuable. The cross was not an act of divine rage directed at the Son. It was an act of divine love in which the Triune God bore the consequences of human sin.

Thomas Oden, the Methodist systematic theologian, captured the balance well when he wrote that Christ suffered in our place to satisfy the radical requirement of God's holiness, removing the obstacle to the pardon and reconciliation of the guilty. And then the crucial line: what the holiness of God required, the love of God provided in the cross.³ That is the balance we must keep before us. God's holiness creates the problem; God's love provides the solution. And both meet at the cross.

"God Is Love" — The Ontological Foundation (1 John 4:8, 16)

We begin where the Bible begins—with love. When the apostle John wrote, "God is love" (1 John 4:8, 16, ESV), he was making one of the most extraordinary claims in all of Scripture. Notice what he did not say. He did not say, "God is loving"—as though love were simply one of many things God happens to do. He said, "God is love." Love is not just an activity of God. Love is something God is. It belongs to His very nature, His very being.

Let me give the full text of the key passage so we can see it in context:

Beloved, let us love one another, for love is from God, and whoever loves has been born of God and knows God. Anyone who does not love does not know God, because God is love. In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him. 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. (1 John 4:7–10, ESV)

This is deeply important for our understanding of the atonement. Notice how John defines love. He does not define it by human experience—our feelings, our romantic attachments, our sentimental notions. He defines love by what God did at the cross. "In this is love," John says—"not that we have loved God but that he loved us and sent his Son to be the propitiation for our sins." The cross is not a contradiction of God's love. The cross is the supreme expression of God's love.

D. A. Carson, in his important book The Difficult Doctrine of the Love of God, has warned against oversimplifying the biblical teaching on God's love. Carson identifies at least five different ways the Bible speaks of God's love: the intra-Trinitarian love between Father, Son, and Spirit; God's providential love over all creation; God's saving love toward the fallen world; God's particular love for His elect people; and God's conditional love that is contingent on obedience.⁴ Carson's point is that we cannot simply take the statement "God is love" and use it to flatten out everything else the Bible says about God. God is love—yes, absolutely. But His love is complex, multidimensional, and always operates in harmony with His other attributes.

Carson's analysis helps us avoid two equal and opposite errors. The first error is sentimentalism—reducing God's love to a warm, fuzzy feeling that makes no moral demands. People who make this mistake imagine a grandfather-in-the-sky God who pats everyone on the head and never says a harsh word. But this "love" is actually indifference dressed up in religious language. A parent who never corrects a child is not displaying love but neglect. In the same way, a God who never opposes evil is not loving—He is morally indifferent. And moral indifference is the opposite of love.

The second error is what we might call "love skepticism"—the tendency to be so focused on God's holiness and wrath that we lose sight of the fact that love really is at the center of who God is. Some presentations of the atonement fall into this trap. They make God sound as though He were primarily interested in punishment, as though love were a secondary consideration that kicks in only after justice has been satisfied. But the Bible will not allow this either. God's love is not an afterthought. It is the foundation of everything He does.

What we need, then, is a robust, biblical understanding of divine love—one that takes seriously the ontological claim of 1 John 4:8 ("God is love") while also recognizing that this love is not sentimental, not permissive, and not soft on evil. God's love is a holy love, a just love, a love that takes sin with deadly seriousness precisely because it takes human beings with deadly seriousness. As Carson argues, God's love is directed toward the undeserving, but it also insists on dealing honestly with the sin that separates us from Him.⁴⁴

This is where many modern discussions of the atonement go wrong. People take "God is love" and conclude that a loving God could never require a sacrifice, could never exercise judgment, could never allow His Son to suffer. But that conclusion does not follow—not if we take seriously the full biblical portrait of who God is. As we are about to see, the Bible teaches not only that God is love but that God is holy, that God is just, and that God's wrath is a real and settled opposition to all evil. A truly loving God does not wink at evil. A truly loving God does something about it.

The Mercy and Justice of God in Tension — Exodus 34:6–7

If 1 John 4:8 gives us one pillar of God's character, Exodus 34:6–7 gives us another. This passage is arguably the most important Old Testament text about the character of God. It is the moment when God reveals His own name—His own nature—to Moses. And what He says is breathtaking:

The LORD passed before him and proclaimed, "The LORD, the LORD, a God merciful and gracious, slow to anger, and abounding in steadfast love and faithfulness, keeping steadfast love for thousands, forgiving iniquity and transgression and sin, but who will by no means clear the guilty, visiting the iniquity of the fathers on the children and the children's children, to the third and the fourth generation." (Exodus 34:6–7, ESV)

Read that slowly. Do you feel the tension? God describes Himself as "merciful and gracious, slow to anger, abounding in steadfast love and faithfulness." That is stunning. But then, in the very same breath, He adds: "but who will by no means clear the guilty." That is sobering.

This passage—often called the "divine name" or the "Exodus creed"—echoes throughout the rest of the Old Testament. Nehemiah quotes it. Jonah alludes to it. Joel draws on it. The Psalms repeatedly echo its language. It became a kind of foundational confession for Israel—their most basic statement about who God is. And the remarkable thing about it is that it holds mercy and judgment together without any attempt to resolve the tension or choose one over the other. God is both. He is merciful and He will not clear the guilty. The Old Testament does not try to smooth over this seeming paradox. It lets it stand, because both halves are true.

Notice the careful balance in the Hebrew. The word chesed (חֶסֶד)—translated "steadfast love" or "lovingkindness"—appears twice in this passage. It is one of the richest words in the Old Testament, conveying the idea of loyal, covenant love—love that keeps its promises, love that never gives up, love that pursues the beloved even when the beloved wanders. This is not a thin, watery love. This is love with backbone. And yet alongside this chesed stands the solemn declaration that God will "by no means clear"—literally "will not make clean" or "will not declare innocent"—the guilty. The Hebrew uses a construction called the infinitive absolute (naqqeh lo yenaqqeh, נַקֵּה לֹא יְנַקֶּה), which intensifies the meaning. God emphatically, absolutely will not treat the guilty as though they were innocent.

Here we see, right in God's own self-revelation, the reality that will drive everything we say about the atonement. God is overflowing with mercy. He forgives iniquity and transgression and sin. And yet He will not simply pretend that guilt does not exist. He will "by no means clear the guilty." How can both be true? How can God be simultaneously the one who forgives sin and the one who refuses to let the guilty go free?

This is exactly the question that the cross answers. As Stott argued in one of the most important chapters ever written on the atonement, the problem of forgiveness is not whether God is willing to forgive. Of course He is willing—He is merciful and gracious, slow to anger, abounding in steadfast love. The problem is how God can forgive without compromising His own character. How can the God who will "by no means clear the guilty" also be the God who pardons sinners?⁵

Stott quoted Carnegie Simpson's elegant summary: "Forgiveness is to man the plainest of duties; to God it is the profoundest of problems."⁶ We tend to think forgiveness should be easy for God. After all, we forgive each other, don't we? Why can't God just do the same? But Stott pointed out that this analogy breaks down at a crucial point. We are private individuals. When someone wrongs us, it is a personal offense. But God is not a private individual. God is the Maker of the moral law. Sin is not merely a personal slight against God—it is rebellion against the moral order of the universe. God cannot simply overlook it any more than a judge can simply dismiss a crime because the criminal says "sorry."⁷

This is the foundation on which the entire doctrine of the atonement rests. God's character creates both the problem and the solution. His holiness and justice demand that sin be dealt with. His love and mercy drive Him to find a way to save sinners. And the cross is where these two meet.

God's Love Takes the Initiative — Romans 5:8

If Exodus 34 shows us the tension within God's character, Romans 5:8 shows us how God resolves it. Paul writes:

But God shows his love for us in that while we were still sinners, Christ died for us. (Romans 5:8, ESV)

Three things in this verse are crucial for understanding the atonement.

First, God's love is initiative-taking, not responsive. God did not wait for us to clean up our act before He loved us. He did not wait for us to reach out to Him. He loved us "while we were still sinners." This demolishes any notion that the atonement was about an angry God who needed to be persuaded to love us. No—God's love came first. The cross was God's idea, not a last resort.

Second, the cross is how God demonstrates His love. Paul does not say that God shows His love by overlooking our sin or by declaring a general amnesty. He says God shows His love by sending Christ to die. The cross is the proof of divine love. It is also the means of divine love. God does not merely feel love toward sinners; He acts on that love by providing a substitute.

Third, notice the phrase "while we were still sinners." Paul is emphatic about this. He elaborates it in the surrounding verses: "while we were still weak" (v. 6), "while we were still sinners" (v. 8), "while we were enemies" (v. 10). We were not lovely. We were not deserving. We were weak, sinful, hostile. And God loved us anyway. David Allen rightly notes that John 3:16 teaches the same point: the motivation for the atonement is the love of God, the scope of that love is the whole world, and Christ is a gift to humanity—where "gave" means not just the incarnation but the crucifixion.⁸

The wider context of Romans 5 makes Paul's point even stronger. In verses 6–10, Paul uses a deliberate progression. We were "weak" (v. 6)—powerless to save ourselves. We were "sinners" (v. 8)—actively rebelling against God. We were "enemies" (v. 10)—in a state of hostility toward the Creator. And at each stage, Paul says that God's love met us there. Christ died for the weak. Christ died for sinners. Christ reconciled us as enemies. The love of God is not a response to our goodness. It is an initiative taken in spite of our badness. This is grace in its purest form.

Paul drives this home by comparing it to human love. "For one will scarcely die for a righteous person—though perhaps for a good person one would dare even to die" (v. 7). Human love, at its very best, might sacrifice itself for someone who is good. But God's love does something unheard of: it sacrifices itself for those who are enemies. This is not the love of sentimentalism. This is a fierce, determined, costly love that nothing can stop. And notice: this love does not bypass the cross. It goes through the cross. The cross is not an obstacle to God's love—it is the instrument of God's love.

The Holiness of God — Isaiah 6:1–5 and Habakkuk 1:13

We have seen that God is love. But that is not all that God is. The Bible also teaches—with thunderous clarity—that God is holy. And unless we grasp the holiness of God, we will never understand why the cross was necessary.

Consider Isaiah's vision in Isaiah 6:1–5:

In the year that King Uzziah died I saw the Lord sitting upon a throne, high and lifted up; and the train of his robe filled the temple. Above him stood the seraphim. Each had six wings: with two he covered his face, and with two he covered his feet, and with two he flew. And one called to another and said: "Holy, holy, holy is the LORD of hosts; the whole earth is full of his glory!" And the foundations of the thresholds shook at the voice of him who called, and the house was filled with smoke. And I said: "Woe is me! For I am lost; for I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the King, the LORD of hosts!" (Isaiah 6:1–5, ESV)

When Isaiah encountered the living God, he did not say, "How wonderful!" He said, "Woe is me! I am lost!" The Hebrew word translated "lost" is the same word used for being cut off, destroyed, ruined. Isaiah experienced firsthand what happens when sinful humanity stands in the presence of the all-holy God. He was undone.

The word "holy"—qadosh (קָדוֹשׁ) in Hebrew—means "set apart, utterly distinct, completely other." God is holy in the sense that He is infinitely different from everything created. He is morally pure, untouched by any shadow of evil. And notice that the seraphim cry "Holy, holy, holy"—three times. In Hebrew, repeating a word intensifies it. Saying it three times is the highest possible intensification. The seraphim are not simply saying God is holy. They are saying God is holy beyond anything we can imagine.

Habakkuk adds another dimension. The prophet writes: "You who are of purer eyes than to see evil and cannot look at wrong" (Habakkuk 1:13a, ESV). This is striking language. God's holiness is so intense, so absolute, that evil cannot exist in His presence. He cannot "look at" wrong—not because He is unaware of it, but because His very nature is incompatible with it.

Stott illustrated this incompatibility with five vivid images from Scripture. God's holiness is like height—He is "the high and lofty One" who dwells in unapproachable exaltation. It is like distance—sinners must keep their distance from the holy God, as Israel was warned at Mount Sinai. It is like light—"God is light, and in him is no darkness at all" (1 John 1:5). It is like fire—"our God is a consuming fire" (Hebrews 12:29). And most dramatically, it is like vomiting—God's rejection of evil is as decisive and visceral as the body's rejection of poison.⁹

These metaphors all point to the same truth: there is something about God's nature that cannot coexist with sin. God's holiness exposes sin. His nature opposes it. Sin cannot approach God, and God cannot tolerate sin. As Stott concluded, all five images "illustrate the utter incompatibility of divine holiness and human sin."¹⁰

Now, why does this matter for the atonement? Because if God were only love and not holy, He could simply wave away sin and forgive without cost. But He is holy. His very nature demands that sin be addressed. This does not make God harsh or cruel. It makes Him real. A God who did not care about evil would not be a God worth worshiping. A God who shrugged at injustice, cruelty, and wickedness would be morally inferior to any decent human being who is outraged by these things. God's holiness is not a problem to be overcome. It is a perfection to be celebrated—and it is one of the things that makes the cross so necessary and so beautiful.

I want to linger here a moment longer, because I think modern Western Christians have largely lost the sense of God's holiness. We live in a casual, informal culture. We call God our "buddy" and imagine Him as someone who just wants us to be happy. But the biblical writers knew better. When they encountered God, they were overwhelmed. Moses hid his face, "for he was afraid to look at God" (Exodus 3:6). The Israelites at Sinai begged Moses to speak to God on their behalf, "lest we die" (Exodus 20:19). Even the seraphim—perfect, sinless, angelic beings—covered their faces in God's presence. If sinless creatures cannot bear to look directly at God's holiness, what hope do sinful human beings have?

Stott lamented that the modern church has lost this vision: "We saunter up to God to claim his patronage and friendship; it does not occur to us that he might send us away." He argued that our evangelical emphasis on the atonement is actually dangerous if we come to it too quickly—before we have first grasped the inaccessibility of God to sinners. "We can cry 'Hallelujah' with authenticity only after we have first cried 'Woe is me, for I am lost.'"⁴⁵ This is profoundly true. The cross means nothing—or rather, it means far less than it should—until we have stood before the holiness of God and felt the weight of our own unworthiness.

R. W. Dale made the same point from a different angle: "It is partly because sin does not provoke our own wrath that we do not believe that sin provokes the wrath of God."⁴⁶ If we took sin as seriously as God does, the cross would not puzzle us at all. It would seem like the most obvious and necessary thing in the world. The problem is not that God overreacts to sin. The problem is that we underreact.

The Wrath of God — Romans 1:18

Of all the attributes of God, wrath is probably the most misunderstood—and the most uncomfortable for modern people. Many Christians squirm at the thought of an angry God. Some scholars have tried to explain divine wrath away entirely. But the Bible is clear: the wrath of God is a real and important part of who God is, and it is essential for understanding the cross.

Paul writes in Romans 1:18:

For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. (Romans 1:18, ESV)

What exactly is the wrath of God? Let me say first what it is not. God's wrath is not a temper tantrum. It is not irrational fury. It is not the kind of explosive, out-of-control anger that we associate with human rage. It is not vindictive, petty, or capricious. All of those things are sinful human distortions of anger, and none of them applies to God.

So what is it? Leon Morris defined God's wrath as His "personal divine revulsion to evil" and His "personal vigorous opposition" to it.¹¹ Charles Cranfield described it as "no nightmare of an indiscriminate, uncontrolled, irrational fury, but the wrath of the holy and merciful God called forth by, and directed against, men's ungodliness and unrighteousness."¹² God's wrath, in other words, is His settled, principled, holy opposition to everything that is evil. It is the necessary response of a perfectly good being to all that is not good.

Think of it this way. If you love children, you will be angry at child abuse. If you love justice, you will be angry at injustice. If you love truth, you will be angry at lies. Your anger in those cases is not a flaw in your character—it is a reflection of your character. In the same way, God's wrath is not a contradiction of His love. It is the reverse side of His love. Because God loves what is good, He opposes what is evil. Because God loves people, He hates the sin that destroys them.

Fleming Rutledge makes this point with great force. She writes that oppressed peoples around the world have been empowered by the scriptural picture of a God who is angered by injustice and unrighteousness. "Where's the outrage?" she asks. The biblical message is that the outrage is first of all in the heart of God. God's anger is pure. It does not serve the maintenance of privilege but goes out on behalf of those who have no privileges. The wrath of God is not an emotion that flares up from time to time, as though God had temper tantrums; it is a way of describing His absolute enmity against all wrong and His coming to set matters right.¹³

Answering the "Impersonal Wrath" Theory

Some scholars have tried to depersonalize God's wrath. The most famous attempt was by C. H. Dodd, who argued that Paul never says God "is angry" with us—he only refers to "wrath" in an impersonal way. Dodd concluded that wrath is not an attitude of God toward humans but rather "an inevitable process of cause and effect in a moral universe."¹⁴ A. T. Hanson expanded on this, arguing that wrath is "wholly impersonal" and "does not describe an attitude of God but a condition of men."¹⁵

Stott responded to this with a penetrating observation. He noted that Hanson's language—saying Paul was "relieved" not to have to attribute wrath directly to God—suggests that Hanson was projecting his own discomfort onto the apostle. Hanson candidly admitted his own prior difficulty with the concept and seemed to shape his exegesis to match his philosophical preferences.¹⁶

But the evidence does not support the impersonal reading. As Stott pointed out, Paul and John both use the full phrase "the wrath of God" without any apparent embarrassment. While Paul sometimes uses the word "wrath" without explicitly naming God, he does the same with "grace"—he speaks of grace "increasing" and "reigning" (Romans 5:20–21) without always naming God. Yet no one concludes from this that grace is an impersonal force. Grace is the most personal of all words—it is God Himself acting graciously toward us. In the same way, wrath is God Himself opposing evil.¹⁷

I find Stott's argument entirely convincing. God's wrath is real, personal, and directed against sin. But it is crucial to understand that it is always principled and controlled. Human anger tends to be arbitrary and spasmodic; divine anger is steady and just. Human anger often seeks revenge; divine anger seeks restoration. Human anger is contaminated by selfishness; divine anger is sustained simultaneously with undiminished love for the offender.¹⁸

Engaging a Critic: William Hess on Divine Wrath

It is worth pausing here to engage with a thoughtful critic of penal substitutionary atonement who has raised important questions about divine wrath. William Hess, in his book Crushing the Great Serpent: Did God Punish Jesus?, argues that none of the key New Testament atonement passages mentions the wrath of God being poured out on the Son, or the Son bearing the wrath of God in our place. Hess contends that the concept of God punishing Jesus to satisfy His wrath is foreign to the biblical witness and that it would violate God's own character to punish an innocent person for the sins of the guilty.⁴⁷

I appreciate Hess's concern. When penal substitution is presented as an enraged Father pouring out uncontrolled fury on an innocent Son, the picture is indeed distorted—as we have already argued. And Hess is right that we should not move too quickly from "God's wrath is real" to "God directed His wrath at Jesus on the cross" without careful biblical and theological reasoning. That is a move that requires substantial argumentation, which we will provide in later chapters (especially Chapters 8, 9, and 19).

However, I think Hess overcorrects. He is so concerned to avoid a wrathful Father-versus-suffering-Son scenario that he removes the penal dimension from the atonement altogether. But as we have seen, God's wrath is not irrational rage—it is the principled response of a holy God to evil. And the biblical language about Christ "bearing sin," being "made sin," and becoming "a curse" for us (as we will examine in Chapters 6 and 9) does involve Christ taking upon Himself the consequences that sin incurs before a holy God. The question is not whether there is a penal dimension, but how to understand it within a properly Trinitarian framework—one in which the Father and Son are not opposed to each other but united in love. That is the framework this book is building, and we believe it addresses Hess's legitimate concerns while preserving the full biblical witness.

Love and Justice Are Not in Tension in God

Now we come to what I consider the most important theological argument in this entire chapter. It is the argument that will shape everything else we say about the atonement in this book.

Many people assume that God's love and God's justice are in conflict—that at the cross, love somehow "won" over justice, or that justice had to be "appeased" before love could flow freely. But this gets things exactly backwards. Love and justice are not in tension in God. They are not competing forces. They are complementary perfections of a single, unified divine nature.

The Psalmist expressed this beautifully: "Steadfast love and faithfulness meet; righteousness and peace kiss each other" (Psalm 85:10, ESV). What an image! Love and faithfulness do not collide—they meet. Righteousness and peace do not battle—they kiss. The cross is the place where this meeting happens. It is not the place where love defeats justice or justice overrides love. It is the place where love and justice are both fully expressed and eternally reconciled.

Emil Brunner, the Swiss Reformed theologian, grasped this with remarkable depth. He insisted that God's nature cannot be captured in a single word. "God is not simply Love," he wrote. The decisive element in the biblical understanding of God is the twofold nature of holiness and love. Modern theology had gone wrong, Brunner argued, by swallowing up holiness in love—replacing the biblical God with a one-dimensional, sentimental deity.¹⁹ Yet for all that, Brunner also insisted that the two attributes are not ultimately opposed. In a daring sentence, he wrote: "The wrath of God is the love of God, in the form in which the man who has turned away from God and turned against God experiences it."²⁰

Let me unpack that, because it is profound. God's love does not change depending on whether we accept or reject Him. God loves sinners. But the experience of that love is different depending on our relationship to Him. For the person who trusts God, His love is experienced as warmth, acceptance, grace. For the person who rebels against God, that same love is experienced as judgment, opposition, wrath. The love is the same. The experience is different. This is why wrath and love are not contradictions but two sides of the same coin.

Stott summed it up with a phrase that I think should be burned into every student of the atonement: God's love is "holy love."²¹ He borrowed this expression from P. T. Forsyth, who wrote: "Christianity is concerned with God's holiness before all else, which issues to man as love.... Without a holy God there would be no problem of atonement. It is the holiness of God's love that necessitates the atoning cross."²²

This is exactly right. If God were love without holiness, there would be no need for a cross—God could simply overlook sin. If God were holiness without love, there would be no cross—God would simply destroy sinners. But because God is both holy and loving, the cross becomes both necessary and possible. His holiness demands that sin be dealt with. His love provides the way.

T. J. Crawford captured the relationship between God's attributes and the cross with great precision. He argued that it is altogether an error to suppose that God acts at one time according to one attribute and at another time according to another. God acts in conformity with all of them at all times. The end of Christ's work was not to bring justice and mercy into harmony, as if they had been at war with each other, but to jointly manifest them both in the redemption of sinners. It is a case of combined action, not counteraction, that is displayed on the cross.²³

The "Problem of Forgiveness" — Why God Cannot Simply Forgive

If love and justice are both fully present in God, then a serious question arises. How can God forgive sinners without compromising His own character? This is what Stott called "the problem of forgiveness," and it is one of the most important theological questions there is.²⁵

Many people think forgiveness should be easy for God. We forgive each other all the time, don't we? If someone wrongs us, we are told to let it go, to forgive and move on. Why can't God do the same?

But as Stott showed, the analogy between human forgiveness and divine forgiveness breaks down at a crucial point. When we forgive someone who has wronged us, we are private individuals letting go of a personal grievance. But God is not a private individual. God is the moral governor of the universe. He is the one who established the moral law. Sin is not merely a personal insult to God—it is a violation of the moral order that God Himself upholds. For God to simply ignore sin would be for Him to deny His own nature. It would be like a judge dismissing every case in his courtroom without regard for the evidence. We would not call such a judge "merciful." We would call him corrupt.²⁶

Anselm of Canterbury made the same point back in the eleventh century. In his famous work Cur Deus Homo? (Why Did God Become Man?), Anselm argued that anyone who thinks God can simply forgive without the cross has "not yet considered the seriousness of sin."²⁷ And Stott added: "You have not yet considered the majesty of God." Both points are necessary. When our understanding of sin's gravity and God's majesty is too small, the cross will always seem unnecessary.

Philippe de la Trinité explored the same question from the Catholic Thomistic tradition. He noted that Thomas Aquinas argued that God could have forgiven humanity without the cross—He had the power to simply remit the debt of sin without requiring satisfaction. But God chose the way of the cross because it was the most fitting way to demonstrate both His justice and His mercy simultaneously. The cross was not a reluctant compromise forced on God. It was the free and wise choice of a God who wanted to display the full depth of His love.²⁸

This is an important nuance. The necessity of the cross is not a necessity imposed on God from outside—as though some external standard of justice forced God's hand. The necessity is internal. It flows from who God is. Because God is holy, He cannot ignore sin. Because God is loving, He will not abandon sinners. Because God is wise, He chose the one path that perfectly satisfies both His justice and His love: the path of self-substitution at the cross.

God's Character in the Hosea 11 Window

One of the most remarkable passages in all of Scripture for understanding the "tension" within God's character is Hosea 11. I put "tension" in quotation marks because, as we have seen, God is not ultimately at odds with Himself. But the way this passage portrays God's inner life is extraordinarily moving.

In Hosea 11, God speaks of Israel as His child, His son, whom He taught to walk, whom He held in His arms, whom He bent down to feed (Hosea 11:1–4). But this beloved child proved wayward and rebellious. Israel turned away from God. They deserved judgment. But then comes this remarkable soliloquy:

How can I give you up, Ephraim? How can I hand you over, Israel? How can I treat you like Admah? How can I make you like Zeboiim? My heart is changed within me; all my compassion is aroused. I will not carry out my fierce anger, nor will I turn and devastate Ephraim. For I am God, and not man—the Holy One among you. I will not come in wrath. (Hosea 11:8–9)

Do you hear the struggle? The four questions beginning with "how can I" bear witness to something happening within God Himself. There is something God ought to do because of His righteousness—judge the rebels. And there is something He cannot bring Himself to do because of His love—destroy them. As Stott observed, the "change of heart" within God is an inner tension between His compassion and His fierce anger.²⁹

Now, we must be careful with anthropomorphic language. God is not conflicted in the way we are. But the Bible uses this kind of language because it communicates something true about God's character. God takes no pleasure in judgment. He is not eager to punish. The destruction of the wicked grieves Him. And yet His holiness means He cannot simply pretend that rebellion never happened.

It is this very "tension"—this holy love that yearns to forgive but cannot ignore sin—that the cross resolves. The cross is God's answer to His own "How can I?" At the cross, God finds a way to satisfy both His justice and His compassion, not by compromising either one, but by bearing the cost Himself.

We should notice one more thing about Hosea 11. God says, "For I am God, and not man—the Holy One among you. I will not come in wrath." This is not a denial of divine wrath. It is a statement that God's response to sin is not limited to wrath. A merely human ruler, faced with rebellion, might respond only with punitive force. But God is not a man. He is the Holy One—and His holiness encompasses both justice and mercy, both wrath and compassion. Because He is God and not man, He can find a way to deal with sin that satisfies His justice without destroying the sinners He loves. That way, as we have argued throughout this chapter, is the cross—where God bears the cost in His own person, so that both His righteousness and His mercy are fully expressed.

The "Cosmic Child Abuse" Caricature — A Distortion of the Cross

With all of this in mind, we are now in a position to address one of the most damaging distortions of the atonement in recent years. In 2003, Steve Chalke and Alan Mann, in their book The Lost Message of Jesus, described penal substitutionary atonement as "cosmic child abuse—a vengeful Father, punishing his Son for an offense he has not even committed."³⁰

This accusation hit the evangelical world like a thunderbolt, and it has been repeated endlessly in the years since. Critics of substitutionary atonement have latched onto the phrase "cosmic child abuse" as a shorthand for everything they find objectionable about the doctrine. And I want to be honest: I understand why the accusation resonates with some people. When penal substitution is presented badly—as though the Father were an enraged deity venting His fury on an innocent and unwilling victim—it does sound like abuse. It sounds like divine violence inflicted on the helpless.

But here is the thing: that is not what substitutionary atonement teaches. The "cosmic child abuse" accusation is an attack on a caricature, not on the real doctrine. And the distortion lies precisely in the way it gets God's character wrong.

Let me be specific about what the caricature gets wrong.

First, the caricature separates the Father from the Son. It pictures the Father as the angry party and the Son as the innocent victim, as though they were on opposite sides. But the Bible teaches that the Father and the Son acted in unified love at the cross. The Father sent the Son because He loved the world (John 3:16). The Son went willingly—"No one takes [my life] from me, but I lay it down of my own accord" (John 10:18, ESV). Paul says both that "God gave him up for us all" (Romans 8:32) and that "Christ loved us and gave himself up for us" (Ephesians 5:2). The giving was mutual. Father and Son acted together, motivated by the same love, pursuing the same purpose.

Philippe de la Trinité explored this unity in detail. Drawing on Thomas Aquinas, he showed that the Father "gave up" Christ not by forcing an unwilling Son to suffer, but by inspiring in Him the desire to suffer voluntarily for our sake. As Aquinas wrote, "It was neither impious nor cruel of God to wish Christ's death. He did not compel him as though it were against his will, but was pleased by the charity which caused Christ to accept his death. And it was he who infused this charity into his soul."³¹ There is no division here. Father and Son are united in the same holy love.

Second, the caricature makes the Father's wrath the primary motive for the cross. In the distorted version, God is angry and needs to vent His anger on someone. Christ happens to be the available target. But the biblical picture is the opposite: the primary motive for the cross is love, not anger. "God so loved the world that he gave his only Son" (John 3:16). "God shows his love for us in that while we were still sinners, Christ died for us" (Romans 5:8). "In this is love, not that we have loved God but that he loved us and sent his Son" (1 John 4:10). Love is the engine that drives the atonement from start to finish.

Third, the caricature ignores the Trinitarian nature of the atonement. The cross is not a transaction between two separate parties—an angry Father and a suffering Son. The cross is the work of the Triune God: Father, Son, and Holy Spirit acting in concert. As Stott argued with great force in his chapter on "The Self-Substitution of God," the cross is best understood as God Himself bearing the cost of our redemption. It is not that God punished someone else. It is that God, in the person of His Son, took upon Himself the consequences of our sin.³² This is self-substitution, not child abuse. The Judge Himself pays the penalty. The Lawgiver Himself bears the cost. We will explore this Trinitarian dimension in much greater depth in Chapter 20.

Allen puts it bluntly: the accusation of "cosmic child abuse" fails to reckon with the voluntary nature of Christ's sacrifice and the Trinitarian unity behind it.³³ When we understand that the Son went willingly, that the Father acted out of love, and that the entire Godhead was united in purpose, the "abuse" charge simply collapses.

The Cross as the Self-Substitution of God

This leads us to what I believe is the single most important insight for understanding the atonement rightly: the cross is God's self-substitution. Stott's treatment of this theme in Chapter 6 of The Cross of Christ is, in my view, one of the finest pieces of theological writing in the twentieth century, and I want to draw on it extensively here.

Stott argued that once we have grasped both the gravity of sin and the majesty of God—once we see ourselves as sinful, responsible, guilty, and lost, and once we see God as holy, just, and loving—then a question confronts us with overwhelming force: How can God express simultaneously His holiness in judgment and His love in pardon?³⁴

His answer: "Only by providing a divine substitute for the sinner, so that the substitute would receive the judgment and the sinner the pardon."³⁵ But who could this substitute be? Not an angel. Not a mere human being. Only God Himself could bear the weight of human sin. And so the breathtaking truth of the gospel is that God did not send someone else to die in our place. He came Himself. He bore the cost Himself. The Judge stepped down from the bench and took the sentence upon Himself.

Stott quoted Charles Cranfield's careful statement: "God, because in his mercy he willed to forgive sinful men, and, being truly merciful, willed to forgive them righteously, that is, without in any way condoning their sin, purposed to direct against his own very self in the person of his Son the full weight of that righteous wrath which they deserved."³⁶ This is the heart of the gospel. God takes the judgment upon Himself. God absorbs the consequences Himself. God pays the price Himself.

Now here is why this matters for our understanding of God's character. The self-substitution of God means that the cross is not an act of one person (the Father) doing something to another person (the Son). It is an act of God doing something to Himself. The Father did not punish someone else. The Father, in the person of His Son, bore the consequences of sin in His own being. This is what makes the cross an act of love rather than an act of violence. This is what distinguishes the true doctrine of substitutionary atonement from the "cosmic child abuse" caricature.

Philippe de la Trinité, writing from the Catholic tradition, reached a remarkably similar conclusion. He argued that the mystery of redemption lies in the fact that it involves an act of divine justice wholly penetrated by divine mercy. We must neither exclude justice—as liberal theology does—nor include it under the aspect of revenge—as some distorted versions of penal substitution do. The cross involves real satisfaction of justice, but this satisfaction was willed by God as good because it makes atonement for the sins of mankind. And this divine will cannot ultimately be explained except as the overflow of merciful love.³⁷

Do you see how beautifully this comes together? The cross is not love versus justice. It is love expressed through justice. It is mercy fulfilling righteousness. It is the holy love of God finding its perfect expression in the self-substitution of the Son.

God's Wrath and God's Love: Not a Contradiction

We have now seen enough to draw together the threads of our argument. Let me state the conclusion as clearly as I can.

The Bible presents God as possessing both wrath and love—and presents these not as contradictions but as complementary aspects of the same holy character. The Bible regularly places these attributes side by side without any suggestion that they are in conflict. Consider these biblical pairings:

Exodus 34:6–7 — "The LORD, a God merciful and gracious... but who will by no means clear the guilty." Psalm 85:10 — "Steadfast love and faithfulness meet; righteousness and peace kiss each other." Isaiah 45:21 — "A righteous God and a Savior." Romans 3:26 — God shows Himself to be "just and the justifier" of the one who has faith (a text we will examine in depth in Chapter 8). 1 John 1:9 — "If we confess our sins, he is faithful and just to forgive us." John 1:14 — The Word made flesh was "full of grace and truth." Romans 11:22 — Paul invites us to consider "the kindness and the severity of God."³⁸

In every one of these pairings, two seemingly opposite attributes are brought together. Mercy and judgment. Grace and truth. Kindness and severity. Love and righteousness. The Bible never suggests that these are in tension. It presents them as dual aspects of a single, infinitely good nature.

This is what Brunner called God's "dual nature"—not meaning that God is divided against Himself, but that His character has a complexity and richness that cannot be captured in a single word. As Brunner wrote, "The cross is the event in which God makes known his holiness and his love simultaneously, in one event, in an absolute manner." The cross is "the only place where the loving, forgiving, merciful God is revealed in such a way that we perceive that his holiness and his love are equally infinite."³⁹

At the same time, we must insist that God is not at war with Himself. He is "the God of peace," of inner tranquility, not turmoil. We find it difficult to hold simultaneously the images of God as the Judge who must punish evil and the Lover who must find a way to forgive. Yet He is both, and at the same time. Calvin, echoing Augustine, wrote that God "in a marvellous and divine way loved us even when he hated us."⁴⁰ The two responses—love for the sinner and hatred for the sin—are not contradictions. They are both expressions of the same holy love.

Implications for How We Understand the Atonement

Everything we have examined in this chapter has direct and far-reaching implications for how we understand what happened at the cross. Let me draw out several of these implications before we conclude.

First, the atonement is grounded in God's love, not His anger. The cross was not Plan B, a desperate measure forced on God by some external demand for blood. The cross was Plan A—the eternal purpose of a God whose very nature is love. "God so loved the world that he gave his only Son." Love is the foundation. Everything else flows from it.

Second, the atonement is necessitated by God's holiness. If God were merely love without holiness, the cross would be unnecessary. But God's holiness means that sin must be dealt with. Sin cannot be swept under the rug. It cannot be ignored. It must be addressed, because the holy God cannot coexist with unaddressed evil. This is why the atonement involves real satisfaction—not because God is petty or vindictive, but because His nature demands that the moral order be upheld.

Third, the atonement is a Trinitarian act, not a transaction between separate parties. The Father, Son, and Spirit acted in unified love at the cross. The Father sent the Son. The Son went willingly. The Spirit sustained Him. There is no division within the Godhead. Any theory of the atonement that pits the Father against the Son—whether explicitly or implicitly—has departed from the biblical witness and from the orthodox Trinitarian faith confessed in the early creeds.

Fourth, wrath and love are both present at the cross, but love is primary. The cross addresses God's wrath against sin—the penal dimension is real, as we will see in later chapters. But the motive for the cross is love. God does not grudgingly provide a sacrifice. He lovingly gives Himself. The wrath is real, but it is a wrath shaped by love and directed by love toward redemptive ends.

Fifth, the cross reveals God's character rather than contradicting it. Some critics suggest that the cross, with its suffering and blood, presents an image of God that is incompatible with a God of love. But the opposite is true. The cross is the supreme revelation of who God is. At the cross we see His holiness (He takes sin seriously), His justice (He does not ignore guilt), His love (He bears the cost Himself), and His mercy (He freely pardons all who trust Him). All of God's attributes are on display, in perfect harmony, at Calvary.

Sixth, distorted views of God's character always produce distorted views of the cross. This is perhaps the most practical implication of everything we have discussed. If we emphasize God's love to the exclusion of His holiness, we end up with a sentimental view of the cross—Jesus died to show us how much God loves us, but there was no real problem of sin that needed solving. This is essentially the moral influence theory taken to an extreme. If we emphasize God's wrath to the exclusion of His love, we end up with a terroristic view of the cross—God is angry and needs blood before He will calm down. Neither of these caricatures does justice to the biblical data. Only when we hold love and holiness together—only when we see the cross as the work of "holy love," in Forsyth's phrase—do we arrive at a faithful understanding of the atonement.

Seventh, the character of God grounds the multi-faceted nature of the atonement. Because God's character is complex—because He is simultaneously loving, holy, just, merciful, wise, and sovereign—the cross accomplishes multiple things at once. It satisfies God's justice (the penal dimension). It demonstrates God's love (the moral dimension). It defeats the powers of evil (the Christus Victor dimension). It provides a pattern for self-giving sacrifice (the exemplary dimension). It restores the broken relationship between God and humanity (the reconciliatory dimension). Each of these facets of the atonement corresponds to a different aspect of God's character. And as we will argue throughout this book, substitution stands at the center—not because the other dimensions are unimportant, but because it is in substitution that all of God's attributes find their fullest expression simultaneously.

What This Means for How We Read the Rest of This Book

As we move forward in this study, the truths we have established in this chapter will serve as our foundation. When we examine the Old Testament sacrificial system in Chapters 4–6, we will see how God's holiness and love shaped the institutions of sacrifice and atonement. When we turn to the New Testament exegesis in Chapters 7–12, we will see how the apostolic writers understood the cross in light of God's character. When we trace the historical development of atonement theology in Chapters 13–18, we will see how different eras emphasized different attributes of God—and how imbalance always led to distortion. When we engage the philosophical objections in Chapters 25–29, we will return again and again to the character of God as the ground on which substitutionary atonement stands or falls.

And when we take up the "cosmic child abuse" objection in detail in Chapter 20 (on the love of the Trinity in the atonement) and Chapter 35 (on contemporary objections), we will be building on the foundation laid here. The answer to the charge of "cosmic child abuse" is not to abandon substitutionary atonement. It is to understand it rightly—as the self-substitution of a Triune God whose holy love drove Him to bear the consequences of our sin in His own person.

Conclusion

We began this chapter by saying that how we understand God determines how we understand the cross. We have now surveyed the biblical teaching on God's love, holiness, justice, and wrath—and we have seen that these are not competing attributes but complementary perfections of a single, unified, infinitely good nature.

God is love—and that love is the driving force behind the atonement. God is holy—and that holiness is why sin must be dealt with. God is just—and that justice is why the cross involves real satisfaction for sin. God's wrath is real—but it is not irrational rage; it is the settled, principled opposition of a holy God to all that is evil, and it is always exercised in harmony with His love.

At the cross, all of these attributes converge. Love provides the sacrifice. Holiness demands it. Justice is satisfied by it. Wrath is absorbed in it. And the result is that God can be, as Paul puts it in Romans 3:26, "both just and the justifier of the one who has faith in Jesus" (a passage we will examine in close detail in Chapter 8). God does not choose between being loving and being just. He is fully and simultaneously both. The cross is where we see this most clearly.

This chapter has been foundational. Everything that follows in this book depends on the truths we have established here. When we turn to the Old Testament sacrificial system in the next chapter, we will see a God who takes sin seriously enough to institute elaborate rituals of atonement—but who also takes love seriously enough to provide those rituals as a gift to His people. When we examine the New Testament texts in later chapters, we will see apostolic writers who understood the cross as the perfect expression of God's holy love. And when we confront the objections—philosophical, theological, moral—we will return again and again to the character of God as the bedrock on which the doctrine of substitutionary atonement stands.

As Stott wrote, "In order to satisfy himself, he sacrificed—indeed substituted—himself for us."⁴¹ That is the heart of the gospel. That is the message of the cross. And it all begins with understanding the character of the God who stands behind it.

In the words of Emil Brunner: "Only he who knows the greatness of wrath will be mastered by the greatness of mercy."⁴² And in the words of P. T. Forsyth: "Without a holy God there would be no problem of atonement. It is the holiness of God's love that necessitates the atoning cross."⁴³

That holy, loving, just, and merciful God is the God we worship. And the cross He provided is the cross we turn to next.
