2 Corinthians 12:9-11, NLT

9Each time he said, “My grace is all you need. My power works best in weakness.” So now I am glad to boast about my weaknesses, so that the power of Christ can work through me. 10That’s why I take pleasure in my weaknesses, and in the insults, hardships, persecutions, and troubles that I suffer for Christ. For when I am weak, then I am strong.

Paul’s Concern for the Corinthians

11You have made me act like a fool. You ought to be writing commendations for me, for I am not at all inferior to these “super apostles,” even though I am nothing at all.
