Second Corinthians 5:21 describes this work of God: “for he made him who knew no sin to be sin for us, that we might become the righteousness of God in him.” Martin Luther rightly called this the great exchange. On the cross Jesus took our sinful on righteousness and gave us his sinless righteousness. In this, we have imputed righteousness and imparted righteousness. In the former, we are declared holy in the side of God. In the latter, we are empowered to live holy lives by the Spirit of God after being born again to live a new life in Christ. It is this truth that allows someone … to be free from the horror of [their] past from Christ, and to look with hope to her future with Christ.
