2 Corinthians 12:5-10

So I will boast about this man — but I will not boast about myself, except the things that show how weak I am. If I wanted to boast, I would not be a fool, because I would be telling the truth. But I will not boast, because I do not want anyone to have a higher opinion of me than he has as a result of what he has seen me do and heard me say. But to keep me from being puffed up with pride because of the many wonderful things I saw, I was given a painful physical ailment, which acts as Satan's messenger to beat me and keep me from being proud. Three times I prayed to the Lord about this and asked him to take it away. But his answer was: “My grace is all you need, for my power is greatest when you are weak.” I am most happy, then, to be proud of my weaknesses, in order to feel the protection of Christ's power over me. I am content with weaknesses, insults, hardships, persecutions, and difficulties for Christ's sake. For when I am weak, then I am strong.
