2 Corinthians 5:17-21

17 Therefore, if anyone is 1in Christ, he is 2a new creation.a3 The old has passed away; behold, the new has come.
18 All this is from God, 4who through Christ reconciled us to himself and gave us 5the ministry of reconciliation;
19 that is, in Christ God was reconcilingb the world to himself, 6not counting their trespasses against them, and entrusting to us 7the message of reconciliation.
20 Therefore, 8we are ambassadors for Christ, 9God making his appeal through us. We implore you on behalf of Christ, be reconciled to God.
21 10For our sake he made him to be sin 11who knew no sin, so that in him we might become 12the righteousness of God.
