2 Corinthians 5:20-21

"Now then, we are ambassadors for Christ, as though GOD were pleading through us; we implore you on Christ's behalf, be reconciled to GOD. 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 5:20-21

He who knew no sin became sin for us so that we might be reconciled to the Father from our sinful nature and our sinful ways. Our sinful nature causes us to have sinful ways! Our repentance is the evidence that we have been born again and are no longer a sinner subject to our sin nature! Repentance is the evidence that we are now subject to Jesus' Lordship!
