John 3:4-17 Revised Standard Version (RSV)
4 Nicode′mus 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 one 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.[a] 7 Do not marvel that I said to you, ‘You must be born anew.’[b] 8 The wind[c] blows where it wills, and you hear the sound of it, but you do not know whence it comes or whither it goes; so it is with every one who is born of the Spirit.” 9 Nicode′mus said to him, “How can this be?” 10 Jesus answered him, “Are you a teacher of Israel, and yet you do not understand this? 11 Truly, truly, I say to you, we speak of what we know, and bear witness to what we have seen; but you do not receive our testimony. 12 If I have told you earthly things and you do not believe, how can you believe if I tell you heavenly things? 13 No one has ascended into heaven but he who descended from heaven, the Son of man.[d] 14 And as Moses lifted up the serpent in the wilderness, so must the Son of man be lifted up, 15 that whoever believes in him may have eternal life.”[e]
16 For God so loved the world that he gave his only Son, that whoever believes in him should not perish but have eternal life. 17 For God sent the Son into the world, not to condemn the world, but that the world might be saved through him.
