2 Corinthians 5:19-21

19that is, that God was in Christ reconciling the world to Himself, not counting people’s sins against them [but canceling them]. And He has committed to us the message of reconciliation [that is, restoration to favor with God].

20So we are ambassadors for Christ, as though God were making His appeal through us; we [as Christ’s representatives] plead with you on behalf of Christ to be reconciled to God.

21He made Christ who knew no sin to [judicially] be sin on our behalf, so that in Him we would become the righteousness of God [that is, we would be made acceptable to Him and placed in a right relationship with Him by His gracious lovingkindness].
