New King James Version (NKJV)
2 Corinthians 12
20 For I fear lest, when I come, I shall not find you such as I wish, and that I shall be found by you such as you do not wish; lest there be contentions, jealousies, outbursts of wrath, selfish ambitions, backbitings, whisperings, conceits, tumults;
21 lest, when I come again, my God will humble me among you, and I shall mourn for many who have sinned before and have not repented of the uncleanness, fornication, and lewdness which they have practiced.
2 Corinthians 13
1 This will be the third time I am coming to you. "By the mouth of two or three witnesses every word shall be established."
2 I have told you before, and foretell as if I were present the second time, and now being absent I write to those who have sinned before, and to all the rest, that if I come again I will not spare--
3 since you seek a proof of Christ speaking in me, who is not weak toward you, but mighty in you.
4 For though He was crucified in weakness, yet He lives by the power of God. For we also are weak in Him, but we shall live with Him by the power of God toward you.
5 Examine yourselves as to whether you are in the faith. Test yourselves. Do you not know yourselves, that Jesus Christ is in you?--unless indeed you are disqualified.
6 But I trust that you will know that we are not disqualified.
7 Now I pray to God that you do no evil, not that we should appear approved, but that you should do what is honorable, though we may seem disqualified.
8 For we can do nothing against the truth, but for the truth.
9 For we are glad when we are weak and you are strong. And this also we pray, that you may be made complete.
