weakness.

"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, in insults, in hardships, in persecutions, in difficulties. for when i am weak, then i am strong."--2 corinthians 12:9-10
