John 3:5

He came to Jesus by night and said to him, “Rabbi, we know that you are a teacher who has come from God, for no one can do these signs that you do, unless God is with him.”

Jesus answered him, “Most certainly I tell you, unless one is born anew, he can’t see God’s Kingdom.”

Nicodemus said to him, “How can a man be born when he is old? Can he enter a second time into his mother’s womb and be born?”

That which is born of the flesh is flesh. That which is born of the Spirit is spirit.

Don’t marvel that I said to you, ‘You must all be born anew.’

The wind blows where it wants to, and you hear its sound, but don’t know where it comes from and where it is going. So is everyone who is born of the Spirit.”
