2 Corinthians 12:8-12

8 Concerning this thing, I begged the Lord three times that it might depart from me.  9 He has said to me, "My grace is sufficient for you, for my power is made perfect in weakness." Most gladly therefore I will rather glory in my weaknesses, that the power of Christ may rest on me.

10 Therefore 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.  11 I have become foolish in boasting. You compelled me, for I ought to have been commended by you, for in nothing was I inferior to the very best apostles, though I am nothing.  12 Truly the signs of an apostle were worked among you in all patience, in signs and wonders and mighty works.
