2 Corinthians 12:6-7

Yet even if I did boast, I would not be foolish. I would simply be speaking the truth. But I will try not to say too much. That way, none of you will think more highly of me than you should because of what you have seen me do and say. Of course, I am now referring to the wonderful things I saw. One of Satan's angels was sent to make me suffer terribly, so that I would not feel too proud.
