John 3:9

5Jesus answered, “Most certainly I tell you, unless one is born of water and Spirit, he can’t enter into God’s Kingdom.

6That which is born of the flesh is flesh. That which is born of the Spirit is spirit.

7Don’t marvel that I said to you, ‘You must all be born anew.’

8The 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.”

9Nicodemus answered him, “How can these things be?”

10Jesus answered him, “Are you the teacher of Israel, and don’t understand these things?

11Most certainly I tell you, we speak that which we know and testify of that which we have seen, and you don’t receive our witness.

12If I told you earthly things and you don’t believe, how will you believe if I tell you heavenly things?

13No one has ascended into heaven but he who descended out of heaven, the Son of Man, who is in heaven.
