2 Corinthians 12:1-3, 7

I must go on boasting. Though there is nothing to be gained by it, 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

So to keep me from becoming conceited because of the surpassing greatness of the revelations, a thorn was given me in the flesh, a messenger of Satan to harass me, to keep me from becoming conceited.
