II Corinthians 12:7-10

"...so I wouldn't get a big head, I was given the gift of a handicap to keep me in constant touch with my limitations. Satan's angel did his best to get me down; what he in fact did was push me to my knees. No danger then of walking around high and mighty! At first I didn't think of it as a gift, and begged God to remove it. Three times I did that, and then He told me, My grace is enough; it's all you need. My strength comes into its own in your weakness. Once I heard that, I was glad to let it happen. I quit focusing on the handicap and began appreciating the gift. It was a case of Christ's strength moving in on my weakness. Now I take limitations in stride, and with good cheer, these limitations that cut me down to size—abuse, accidents, opposition, bad breaks. I just let Christ take over! And so the weaker I get, the stronger I become."
~ II Corinthians 12:7-10 (The Message)

"...in order to keep me from becoming conceited, I was given a thorn in my flesh, a messenger of Satan, to torment me. Three times I pleaded with the Lord to take it away from me. 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, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong. ~II Corinthians 12:7-10 (NIV)
