2 Corinthians 12:5-7

That experience is worth boasting about, but I’m not going to do it. I will boast only about my weaknesses. If I wanted to boast, I would be no fool in doing so, because I would be telling the truth. But I won’t do it, because I don’t want anyone to give me credit beyond what they can see in my life or hear in my message, even though I have received such wonderful revelations from God. So to keep me from becoming proud, I was given a thorn in my flesh, a messenger from Satan to torment me and keep me from becoming proud.
