II Corinthians 5:11-13

Knowing, therefore, the terror of the Lord, we persuade men; but we are well known to God, and I also trust are well known in your consciences. For we do not commend ourselves again to you, but give you opportunity to boast on our behalf, that you may have an answer for those who boast in appearance and not in heart. For if we are beside ourselves, it is for God; or if we are of sound mind, it is for you.
