2 Corinthians 12:2-3 

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. 

There are some things we know and other things we don’t know. We shouldn’t insist on demanding to “know” all the whys, how’s, and when’s. The important thing is that God knows.
