2 Corinthians 12:1-3, 7

I must needs glory, though it is not expedient; but I will come to visions and revelations of the Lord. I know a man in Christ, fourteen years ago (whether in the body, I know not; or whether out of the body, I know not; God knoweth), such a one caught up even to the third heaven. And I know such a man (whether in the body, or apart from the body, I know not; God knoweth)

And by reason of the exceeding greatness of the revelations, that I should not be exalted overmuch, there was given to me a thorn in the flesh, a messenger of Satan to buffet me, that I should not be exalted overmuch.
