Although if I should wish to boast, I would not be foolish, for I would be telling the truth.  But I refrain, so that no one may think more of me than what he sees in me or hears from me because of the abundance of the revelations.

Therefore, that I might not become too elated, a thorn in the flesh was given to me, an angel of Satan, to beat me, to keep me from being too elated.  Three times I begged the Lord about this, that it might leave me, but he said to me, “My grace is sufficient for you, for power is made perfect in weakness.”  I will rather boast most gladly of my weaknesses, in order that the power of Christ may dwell with me.  Therefore, I am content with weaknesses, insults, hardships, persecutions, and constraints, for the sake of Christ; for when I am weak, then I am strong.

II Corinthians 12:6-10
