'Weaknesses' in the Bible

On behalf of such a one I will boast, but on my own behalf I will not boast, except in my weaknesses.

He has said to me, "My grace is sufficient for you, for my power is made perfect in weakness." Most gladly therefore I will rather glory in my weaknesses, that the power of Christ may rest on me.

Therefore I take pleasure in weaknesses, in injuries, in necessities, in persecutions, in distresses, for Christ's sake. For when I am weak, then am I strong.
