2 Corinthians 5:17-21

So if any one be in Christ, there is a new creation; the old things have passed away; behold all things have become new: and all things are of the God who has reconciled us to himself by Jesus Christ, and given to us the ministry of that reconciliation: how that God was in Christ, reconciling the world to himself, not reckoning to them their offences; and putting in us the word of that reconciliation. We are ambassadors therefore for Christ, God as it were beseeching by us, we entreat for Christ, Be reconciled to God. Him who knew not sin he has made sin for us, that we might become God's righteousness in him.
