2 Corinthians 12:1-6

It is necessary to boast, though nothing is 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—whether in the body I do not know, or out of the body I do not know, [only] God knows—such a man was caught up to the third heaven. [Luke 23:43] And I know that such a man—whether in the body or out of the body I do not know, [only] God knows— was caught up into Paradise and heard inexpressible words which man is not permitted to speak [words too sacred to tell]. On behalf of such a man [and his experiences] I will boast; but in my own behalf I will not boast, except in regard to my weaknesses. If I wish to boast, I will not be foolish, because I will be speaking the truth. But I abstain [from it], so that no one will credit me with more than [is justified by what] he sees in me or hears from me.
