Final Warnings and Greetings

13 This is the third time I am coming to you. “In the mouth of two or three witnesses shall every word be established.”^{[a] 2} I told you before, and foretell as if I were present the second time. And being absent now, I write to those who have sinned before, and to all the others, that if I come again, I will not spare anyone, ³ since you seek proof of Christ speaking through me, who toward you is not weak, but is mighty in you. ⁴ For though He was crucified through weakness, yet He lives by the power of God. So also we are weak in Him, but we shall live with Him by the power of God serving you.
