'Born of the Spirit' in the Bible

That which is born of the flesh is flesh [the physical is merely physical], and that which is born of the Spirit is spirit.

The wind blows where it wishes and you hear its sound, but you do not know where it is coming from and where it is going; so it is with everyone who is born of the Spirit.”

I assure you and most solemnly say to you, we speak only of what we [absolutely] know and testify about what we have [actually] seen [as eyewitnesses]; and [still] you [reject our evidence and] do not accept our testimony.
