II Corinthians 12:20-21

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; 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.
