But 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. That is why for Christ's sake, I delight in weaknesses, Insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong.
(2 Corinthians 12:9-10 NIV);
