2 Corinthians 12:7-10 New Revised Standard Version (NRSV)
7 even considering the exceptional character of the revelations. Therefore, to keep[a] me from being too elated, a thorn was given me in the flesh, a messenger of Satan to torment me, to keep me from being too elated.[b] 8 Three times I appealed to the Lord about this, that it would leave me, 9 but he said to me, “My grace is sufficient for you, for power[c] is made perfect in weakness.” So, I will boast all the more gladly of my weaknesses, so that the power of Christ may dwell in me. 10 Therefore I am content with weaknesses, insults, hardships, persecutions, and calamities for the sake of Christ; for whenever I am weak, then I am strong.
