2 Corinthians 5 [15.] He died for all, that those who live should no longer live to themselves, but to him who for their sakes died and rose again. Therefore we know no one after the flesh from now on. Even though we have known Christ after the flesh, yet now we know him so no more. Therefore if anyone is in Christ, he is a new creation. The old things have passed away. Behold,[a] all things have become new. But all things are of God, who reconciled us to himself through Jesus Christ, and gave to us the ministry of reconciliation; namely, that God was in Christ reconciling the world to himself, not reckoning to them their trespasses, and having committed to us the word of reconciliation.
2 Corinthians 5 [20.] We are therefore ambassadors on behalf of Christ, as though God were entreating by us: we beg you on behalf of Christ, be reconciled to God. For him who knew no sin he made to be sin on our behalf; so that in him we might become the righteousness of God.
2 Corinthians 6 [1.] Working together, we entreat also that you not receive the grace of God in vain, 2 Corinthians 6 [2.] for he says,
“At an acceptable time I listened to you,
in a day of salvation I helped you.”[a]
Behold, now is the acceptable time. Behold, now is the day of salvation. We give no occasion of stumbling in anything, that our service may not be blamed, but in everything commending ourselves, as servants of God, in great endurance, in afflictions, in hardships, in distresses, in beatings, in imprisonments, in riots, in labors, in watchings, in fastings; in pureness, in knowledge, in patience, in kindness, in the Holy Spirit, in sincere love, in the word of truth, in the power of God; by the armor of righteousness on the right hand and on the left, by glory and dishonor, by evil report and good report; as deceivers, and yet true; as unknown, and yet well known; as dying, and behold, we live; as punished, and not killed; as sorrowful, yet always rejoicing; as poor, yet making many rich; as having nothing, and yet possessing all things.
