2 Corinthians 12:5-10

ISV(i) 5 I will boast about this man, but as for myself I will boast only about my weaknesses. 6 However, if I did want to boast, I would not be a fool, because I would be telling the truth. But I am not going to do it in order to keep anyone from thinking more of me than what he sees and hears about me.
7 To keep me from becoming conceited because of the exceptional nature of these revelations, a thorn was given to me and placed in my body. It was Satan’s messenger to keep on tormenting me so that I would not become conceited.
8 I pleaded with the Lord three times to take it away from me, 9 but he has told me, “My grace is all you need, because my power is perfected in weakness.” Therefore, I will most happily boast about my weaknesses, so that the Messiah’s power may rest on me. 10 That is why I take such pleasure in weaknesses, insults, hardships, persecutions, and difficulties for the Messiah’s sake, for when I am weak, then I am strong.
