'Weaknesses' in the Bible

I will boast about this man, but as for myself I will boast only about my weaknesses.

but he has told me, "My grace is all you need, because my power is perfected in weakness." Therefore, I will most happily boast about my weaknesses, so that the Messiah's power may rest on me.

That is why I take such pleasure in weaknesses, insults, hardships, persecutions, and difficulties for the Messiah's sake, for when I am weak, then I am strong.
