John 3:5-8

5Jesus answered, “I assure you and most solemnly say to you, unless one is born of water and the Spirit he cannot [ever] enter the kingdom of God.

6That which is born of the flesh is flesh [the physical is merely physical], and that which is born of the Spirit is spirit.

7Do not be surprised that I have told you, ‘You must be born again [reborn from above—spiritually transformed, renewed, sanctified].’

8The 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.”
