2 Corinthians 12:19-21

19Again, think ye that we excuse ourselves unto you? we speak before God in Christ: but we do all things, dearly beloved, for your edifying.

20For I fear, lest, when I come, I shall not find you such as I would, and that I shall be found unto you such as ye would not: lest there be debates, envyings, wraths, strifes, backbitings, whisperings, swellings, tumults:

21And lest, when I come again, my God will humble me among you, and that I shall bewail many which have sinned already, and have not repented of the uncleanness and fornication and lasciviousness which they have committed.
