2 Corinthians 12:9-11 ESV
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 of my weaknesses, so that the power of Christ may rest upon me. For the sake of Christ, then, I am content with weaknesses, insults, hardships, persecutions, and calamities. For when I am weak, then I am strong.
I have been a fool! You forced me to it, for I ought to have been commended by you. For I was not at all inferior to these super-apostles, even though I am nothing.
