He promises to come to them, and he exhorts them to get themselves in order so that he may find them perfect and in harmony.

13 Now I am coming the third time to you. In the mouth of two or three witnesses shall everything be established. ² I told you before and I am warning you now, and as I said when I was present with you the second time, so I write now, being absent, to those who in time past have sinned and to all others: if I come again, I will not spare, ³ seeing that you seek proof of Christ who speaks in me – who among you is not weak, but is mighty in you. ⁴ And indeed, though it came of weakness that he was crucified, yet he lives through the power of God. And we no doubt are weak in him, but we shall live with him by the might of God among you.
