I must boast; there is nothing to be gained by it, but I will go on to visions and revelations of the Lord. I know a man in Christ who fourteen years ago was caught up to the third heaven—whether in the body or out of the body I do not know, God knows. And I know that this man was caught up into Paradise—whether in the body or out of the body I do not know, God knows— and he heard things that cannot be told, which man may not utter. On behalf of this man I will boast, but on my own behalf I will not boast, except of my weaknesses. Though if I wish to boast, I shall not be a fool, for I shall be speaking the truth. But I refrain from it, so that no one may think more of me than he sees in me or hears from me. And to keep me from being too elated by the abundance of revelations, a thorn was given me in the flesh, a messenger of Satan, to harass me, to keep me from being too elated. Three times I besought the Lord about this, that it should leave me; but he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” I will all the more gladly boast of my weaknesses, 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.
–2 Corinthians 12:1-10
