2 Corinthians 5:21

For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God. 2 Corinthians 5:21

God so charged Christ, implicated him, loaded him with our sin, that at the cross he was treated as if he embodied our sin, so that we, just because we are in Christ and for no other reason, might be treated as if we embodied the righteousness of God, perfectly fulfilling his law, receiving the smile and welcome of the Judge.

It is finished.
