2 Corinthians 5:16-21 NASB
16 Therefore from now on we recognize no one according to the flesh; even though we have known Christ according to the flesh, yet now we know Him in this way no longer. 17 Therefore if anyone is in Christ, he is a new creature; the old things passed away; behold, new things have come. 18 Now all these things are from God, who reconciled us to Himself through Christ and gave us the ministry of reconciliation, 19 namely, that God was in Christ reconciling the world to Himself, not counting their trespasses against them, and He has committed to us the word of reconciliation.
20 Therefore, we are ambassadors for Christ, as though God were making an appeal through us; we beg you on behalf of Christ, be reconciled to God. 21 He made Him who knew no sin to be sin on our behalf, so that we might become the righteousness of God in Him.
