2 Cor 12: 5-10 (NIV)

⁵I will boast about a man like that, but I will not boast about myself, except about my weaknesses. ⁶Even if I should choose to boast, I would not be a fool, because I would be speaking the truth. But I refrain, so no one will think more of me than is warranted by what I do or say.

⁷To keep me from becoming conceited because of these surpassingly great revelations, there was given me a thorn in my flesh, a messenger of Satan, to torment me. ⁸Three times I pleaded with the Lord to take it away from me. ⁹But he said to me, "My grace is sufficient for you, for my power is made perfect in weakness." Therefore I will boast all the more gladly about my weaknesses, so that Christ's power may rest on me. ¹⁰That is why, for Christ's sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong.

To remind me to always allow the LORD to rest his power on me, for his strength is made perfect in my weakness.
