2 Corinthians 12:7-9

7or because of these surpassingly great revelations.

So to keep me from becoming conceited,1 I was given a thorn in my flesh, a messenger of Satan, to torment me. 8Three times I pleaded with the Lord to take it away from me. 9But He said to me, “My grace is sufficient for you, for My power is perfected in weakness.” Therefore I will boast all the more gladly in my weaknesses, so that the power of Christ may rest on me.
