That is what I meant. Some read that passage assuming they understand what "born of the Spirit" means; and when they reach that verse, they skip over it without asking themselves if they really do understand. Then the question is if Nicodemus understood.Thank you for directing my attention to 31. Let me get back to you.
I noticed the "being able to move like the wind", and, that is a lot like:
Marvel not that I said unto thee, Ye must be born again. The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
If it is Old Testament material, where is it discussed?
