Paul's Second Letter to the Corinthians (WEB)
13: 1This is the third time I am coming to you. "At the mouth of two or three witnesses shall every word established." 13:2I 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; 13:3seeing that you seek a proof of Christ that speaks in me; who toward you is not weak, but is powerful in you. 13:4For 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. 13:5Test 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. 13:6But I hope that you will know that we aren't disqualified.
13:7Now 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. 13:8For we can do nothing against the truth, but for the truth. 13:9For we rejoice when we are weak and you are strong. And this we also pray for, even your perfecting. 13:10For 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. 13:11Finally, brothers, rejoice. Be perfected, be comforted, be of the same mind, live in peace, and the God of love and peace will be with you. 13:12Greet one another with a holy kiss. 13:13All the saints greet you. 13:14The grace of the Lord Jesus Christ, the love of God, and the communion of the Holy Spirit, be with you all. Amen.
