3Jesus answered him, "Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God." 4Nicodemus 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?" 5Jesus answered, "Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. 6That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. 7Do not marvel that I said to you, 'You must be born again.' 8The 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."
