I know a man in Christ who fourteen years ago was caught up to the third heaven. Whether it was in the body or out of the body I do not know — God knows. And I know that this man — whether in the body or apart from the body I do not know, but God knows — was caught up to paradise. He heard in expressible things, things that man is not permitted to tell. I will boast about a man like that, but I will not boast about myself, except about my weaknesses. Even if I should choose to boast, I would not be a fool, because I would be speaking the truth. But I refrain, so no one will think more of me than is warranted by what I do or say.
To keep me from becoming conceited because of these surpassingly great revelations, there was given me a thorn in my flesh, a messenger of Satan, to torment me. Three times I pleaded with the Lord to take it away from me. But he said to me, “My grace is sufficient for you , for my power is made perfect in weakness.’ Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me. That is why, for Christ’s sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, I am strong.
2 Corinthians 12:2-10
