John 3:7-11

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.

Nicodemus answered and said unto him, How can these things be?

Jesus answered and said unto him, Art thou a master of Israel, and knowest not these things?

Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness.
