2 Corinthians 5:15-21

and he died for all, that they that live should no longer live unto themselves, but unto him who for their sakes died and rose again. Wherefore we henceforth know no man after the flesh: even though we have known Christ after the flesh, yet now we know him so no more. Wherefore if any man is in Christ, he is a new creature: the old things are passed away; behold, they are become new. But all things are of God, who reconciled us to himself through Christ, and gave unto us the ministry of reconciliation; to wit, that God was in Christ reconciling the world unto himself, not reckoning unto them their trespasses, and having committed unto us the word of reconciliation. We are ambassadors therefore on behalf of Christ, as though God were entreating by us: we beseech you on behalf of Christ, be ye reconciled to God. Him who knew no sin he made to be sin on our behalf; that we might become the righteousness of God in him.
