2 Corinthians 12:9-13

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. I am become foolish: ye compelled me; for I ought to have been commended of you: for in nothing was I behind the very chiefest apostles, though I am nothing. Truly the signs of an apostle were wrought among you in all patience, by signs and wonders and mighty works. For what is there wherein ye were made inferior to the rest of the churches, except it be that I myself was not a burden to you? forgive me this wrong.
