2 Corinthians 5:21: the exchange that closes the reconciliation argument
21For God made him who did not know sin to be sin for us, so that we might become the justice of God in him.
An exchange in two movements, built on an absolute contrast: the one who did not know sin, and us. This edition calls the result the justice of God — not an example to copy, but something done in our place.
Short answer
2 Corinthians 5:21 says God placed the one who had no acquaintance with sin into the position of sin on our behalf, so that in him we might come to be God’s own justice. It seals the passage where Paul describes the ministry of reconciliation and pleads with his readers to be reconciled to God.

It is among the densest verses in the New Testament, and every word of it has been argued over for centuries. Before any theological dispute, though, it is the last sentence of an appeal — and reading the appeal first explains why Paul ends this way.
Where this verse appears
Paul is defending his own ministry before a church that had grown suspicious of him. In the preceding verses he describes God reconciling the world to himself and entrusting the message of that reconciliation to the apostles; he calls himself an ambassador and makes a direct plea for his readers to be reconciled to God. Verse 21 is the reason given for the plea.
What it says
The structure is an exchange. On one side, someone described as having no acquaintance with sin; on the other, the people addressed. The verb applied to the first is too strong to be smoothed over, and Paul chose it for that reason: this is not someone merely showing solidarity, but someone put in the place of others.
The closing phrase is the most debated. This edition reads the justice of God, where many versions read the righteousness of God; the underlying Greek word covers both, and nothing turns on which English word is chosen. It can be read as a standing granted to the believer or as a share in what God is and does, and Christian traditions weight those differently. Either way, God is the one acting, and the final preposition decides everything: this happens in him, not on your own account.
Notice what the verse does not do. In this sentence Jesus is not offered as a moral model to copy, and no effort is assigned to the reader. The whole grammar is of an external act received — which is why the preceding appeal is to accept a reconciliation rather than to negotiate one.
What to do with it today
For anyone who lives trying to keep square with God, this verse moves the whole account. What is at stake is not your balance but an exchange already made. That does not remove responsibility, but it changes the starting point: you are not trying to get in, you are being asked to accept that the door opened.
It also shapes how you look at other people. Paul draws that conclusion just before: whoever received reconciliation received with it the job of announcing it. The passage ends in ministry, not in private comfort.
A prayer to carry with you
Lord, I still try to pay what has already been paid. Teach me to receive instead of negotiating. And let what I was given freely show up in how I treat people who still feel far off. Amen.
