2 Corinthians 5:21 Meaning: The Great Exchange

The Greek word ἁμαρτία (hamartia) appears twice in this verse, but the meaning shifts. In the first instance, Paul says Christ “knew no sin.” The verb “knew” (γινώσκω, ginōskō) here carries the sense of personal experience, Christ had no firsthand acquaintance with sin. The negative particle μή (mē) is used instead of the usual οὐ, which points to Christ’s own awareness of his sinlessness. He knew within himself that he was innocent.

In the second use, “he made to be sin,” the same word ἁμαρτία takes on a different force. For readers familiar with the Greek Old Testament, this word often translated the Hebrew chatta’th, which can mean either “sin” or “sin-offering.” Many early Christian writers heard an echo of the altar here: Jesus was treated as the sacrifice that carries sin away.

The amazing result is that we “might become the righteousness of God” (δικαιοσύνη θεοῦ, dikaiosynē theou). This is not merely being called “not guilty.” It is a positive standing, a gift of full acceptance that comes from God himself and is ours in Christ.

Christians across traditions have read this verse with awe, though they have emphasized different aspects. Some, like Methodist commentator Adam Clarke and many in the Wesleyan tradition, understand “made sin” to mean “made a sin-offering.” They point to the Old Testament pattern where a lamb without blemish bore the people’s guilt symbolically. Others, such as Reformed and Baptist interpreters (Calvin, Gill, JFB), stress the idea of imputation: Christ bore the full legal weight of sin on behalf of his people, so that his righteousness could be credited to them. Anglican and Lutheran commentators often highlight the “great exchange” itself, Christ took what we deserved so we could receive what he deserved. All agree that the verse speaks of a substitution that is at the heart of the gospel, though they describe that substitution in slightly different language. What unites them is the conviction that our salvation rests entirely on what God did in Christ.

This verse gives you a solid place to stand when your own failures or doubts shout louder than God’s promise. You don’t have to work your way into God’s favor. Christ already took the full weight of your sin so that you could receive his perfect righteousness. When you feel condemned, remember that your identity is not in your performance but in the exchange Christ made for you. This week, when guilt or shame presses in, quietly say to yourself: “God made him sin for me, so that in him I am the righteousness of God.” Let that truth loosen the grip of your mistakes. And then, because you are free, look for someone to whom you can be an ambassador of that same reconciliation.
