2 Corinthians 12:7-10

And by reason of the exceeding greatness of the revelations, that I should not be exalted overmuch, there was given to me a thorn in the flesh, a messenger of Satan to buffet me, that I should not be exalted overmuch. Concerning this thing I besought the Lord thrice, that it might depart from me. And he hath said unto me, My grace is sufficient for thee: for my power is made perfect in weakness. Most gladly therefore will I rather glory in my weaknesses, that the power of Christ may rest upon me. Wherefore I take pleasure in weaknesses, in injuries, in necessities, in persecutions, in distresses, for Christ’s sake: for when I am weak, then am I strong.
