For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him.2 Corinthians
Righteousness is not about right conduct. It is a gift from God to us through Jesus. And since it is a gift, we cannot earn it by our law-keeping and right conduct. We can only receive it!
How do we receive this gift? We receive it through the cross. God made Jesus “who knew no sin to be sin for us that we might become the righteousness of God in Him”. So today, we are the righteousness of God in Christ. We are as righteous as Jesus is!
When God gave us Jesus, He became our righteousness. So we have His righteousness. This means that we are 100 per cent righteous in God’s eyes! We cannot but have first-class righteousness!
At the cross, the divine exchange took place. Jesus took our place so that we might take His place. He did not deserve to be made sin, but He was made sin in our place. We did not deserve to be made righteous, but we were made righteous because we received His righteousness. What good news! What amazing grace!
