Context / meaning
2 Corinthians 12 [20.] For I am afraid that by any means, when I come, I might find you not the way I want to, and that I might be found by you as you don’t desire; that by any means there would be strife, jealousy, outbursts of anger, factions, slander, whisperings, proud thoughts, riots; that again when I come my God would humble me before you, and I would mourn for many of those who have sinned before now, and not repented of the uncleanness and sexual immorality and lustfulness which they committed.
2 Corinthians 13 [1.] This is the third time I am coming to you. “At the mouth of two or three witnesses shall every word be established.”[a] I have said beforehand, and I do say beforehand, as when I was present the second time, so now, being absent, I write to those who have sinned before now, and to all the rest, that, if I come again, I will not spare; seeing that you seek a proof of Christ who speaks in me; who toward you is not weak, but is powerful in you. For he was crucified through weakness, yet he lives through the power of God. For we also are weak in him, but we will live with him through the power of God toward you. [5.] Examine your own selves, whether you are in the faith. Test your own selves. Or don’t you know as to your own selves, that Jesus Christ is in you?—unless indeed you are disqualified. But I hope that you will know that we aren’t disqualified.
2 Corinthians 13 [7.] Now I pray to God that you do no evil; not that we may appear approved, but that you may do that which is honorable, though we are as reprobate. For we can do nothing against the truth, but for the truth. For we rejoice when we are weak and you are strong. And this we also pray for, even your perfecting. For this cause I write these things while absent, that I may not deal sharply when present, according to the authority which the Lord gave me for building up, and not for tearing down.
