His death and resurrection means that if I trust him, I am justified. By faith alone, I am clothed in the perfect righteousness of Jesus himself. He takes all my sin, and he gives me all his righteousness, never to be taken away. (2 Cor. 5.21)

Dane Ortlund

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 Cor. 5:21)
