“Nicodemus answered and said unto him, How can these things be?”
King James Version (KJV)
3:7 Ye must be born again - To be born again, is to be inwardly changed from all sinfulness to all holiness. It is fitly so called, because as great a change then passes on the soul as passes on the body when it is born into the world.
3:8 The wind bloweth - According to its own nature, not thy will, and thou hearest the sound thereof - Thou art sure it doth blow, but canst not explain the particular manner of its acting. So is every one that is born of the Spirit - The fact is plain, the manner of his operations inexplicable.
3:11 We speak what we know - I and all that believe in me.
