The Work of Christ: More than God's Justice

Robert LethamTony Reinke said in his book Lit! that, along with whatever else he is reading, he tries to always be in book on the work of Christ. This desire surely needs little explanation if you are a Christian. But before you think I am laying on the guilt, let me admit that in 2018 I read only two books on the work of Christ, and both of those were at Easter. One of them was Robert Letham’s The Work of Christ. And it is my intention to post some reflections on it over the next month as we head towards Easter this year. You are reading the first post in this series which - along with the second - will be thinking about penal substitutionary atonement (PSA), which Letham defines as, “Christ himself willingly submitted to the just penalty which we deserved, receiving it on our behalf and in our place so that we will not have to bear it ourselves” (p133).

Numerous objections have been raised against PSA through the years and today the doctrine is perhaps facing some of its harshest criticism to date. Letham outlines and addresses two popular objections to PSA: (a) it seems unjust; (b) and therefore raises questions about God’s character. Letham more than adequately rebuffs these criticisms and defends the biblical, just and loving doctrine of PSA. But I want to touch on a third issue he interacts with, “Today there is almost universal distaste for thinking of God and salvation in legal categories” (p137). In other words, many feel that PSA reduces God’s grace to a cold transaction devoid of affection, or “stock-exchange divinity”, as Edward Irving called it. How do we answer this objection?

Briefly Letham shows how the Bible speaks very positively about God’s law. Quoting from a handful of Psalms he argues that God’s judgments are deemed perfect, and those who meditate on his justice are called wise. In the Gospels we do not see Jesus abolishing the law but rather pressing its demands upon the entire person, “requiring total and lifelong dedication to the service of God’s kingdom.” Furthermore, while Paul asserts the law’s inability to save in Romans he is careful and clear not to reject it (Romans 3:31; 7:12, 14). So, regardless of our dislike for legal categories, the Bible affirms them; God’s justice, righteousness and judgment are not merely good, but perfect.

Letham then provides a second argument against those who would reject PSA, on the grounds of it being abstract, too ledger like, or extrinsic. He writes, “It may be helpful for us to see the penal substitutionary death of Christ in the context of God’s loving provision for the deliverance of those who otherwise were without hope…The atonement stems from the love of God and, since God’s love is just love and his justice is loving justice, the cross is a demonstration par excellence of that love in a way that is commensurate with his justice” (p138). You should probably read that quote again. Letham’s point is that instead of divorcing God’s love from legal categories, the Bible holds them together. “God’s amazing love had to be righteous as well” (p139).

This post is more technical than I aim to be here, so let me keep it short and attempt to offer a neat conclusion. PSA is a central idea in both Old and New Testaments. But far from seeming to reduce God to justice crazed tyrant, in God’s provision of a substitute - ultimately his own Son - we see God’s crazy love (thanks Francis Chan). The cross beautifully demonstrates God’s love and his justice. In love Christ faces my judgment. His perfect justice partners his love and removes the penalty for sin. Hear Letham one last time, “Sin is so central to to the New Testament portrayal of the atonement that a theory which leaves it on one side is deficient” (p163). PSA upholds God’s perfect justice, presents us with God’s great love and pardons us of our sin. To adapt a few lines from O Church Arise: Come see the cross, where love and justice meet.
