Gospel of John, Chapter 3

3 Jesus answered him, “Truly, truly I say to you, unless a man is born again, he cannot see the kingdom of God.”

4 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?”

5 Jesus answered, “Truly, truly I say to you, unless a man is born of water and the Spirit, he cannot enter the kingdom of God.

6 That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.

7 Do not marvel that I said to you, ‘You must be born again.’

8 The wind blows where it wishes, and you hear its sound, but you do not know where it comes from or where it goes. So it is with everyone who is born of the Spirit.”
