12:20. For I fear lest perhaps, when I come, I shall not find you such as I would, and that I shall be found by you such as you would not. Lest perhaps contentions, envyings, animosities, dissensions, detractions, whisperings, swellings, seditions, be among you.
12:21. Lest again, when I come, God humble me among you: and I mourn many of them that sinned before and have not done penance for the uncleanness and fornication and lasciviousness that they have committed.
2 Corinthians Chapter 13
He threatens the impenitent, to provoke them to penance.
13:1. Behold, this is the third time I am coming to you: In the mouth of two or three witnesses shall every word stand.
13:2. I have told before and foretell, as present and now absent, to them that sinned before and to all the rest, that if I come again, I will not spare.
13:3. Do you seek a proof of Christ that speaketh in me, who towards you is not weak, but is mighty in you?
13:4. For although he was crucified through weakness, yet he liveth by the power of God. For we also are weak in him: but we shall live with him by the power of God towards you.
13:5. Try your own selves if you be in the faith: prove ye yourselves. Know you not your own selves, that Christ Jesus is in you, unless perhaps you be reprobates?
13:6. But I trust that you shall know that we are not reprobates.
