2 Corinthians 12:4-7

was caught up into Paradise and heard inexpressible words, which a man is not permitted to speak. On behalf of such a man I will boast; but on my own behalf I will not boast, except in regard to my weaknesses. For if I do wish to boast I will not be foolish, for I will be speaking the truth; but I refrain from this, so that no one will credit me with more than he sees in me or hears from me. Because of the surpassing greatness of the revelations, for this reason, to keep me from exalting myself, there was given me a thorn in the flesh, a messenger of Satan to torment me—to keep me from exalting myself!
