But to keep me from being puffed up with pride because of the many wonderful things I saw, I was given a painful physical ailment, which acts as Satan’s messenger to beat me and keep me from being proud. Three times I prayed to the Lord about this and asked him to take it away. But his answer was: “My grace is all you need, for my power is greatest when you are weak.” I am most happy, then, to be proud of my weaknesses, in order to feel the protection of Christ’s power over me.
2 Corinthians 12:7-9
