7Do not be astonished that I said to you, “You must be born from above.”8The wind blows where it chooses, and you hear the sound of it, but you do not know where it comes from or where it goes. So it is with everyone who is born of the Spirit.’ 9Nicodemus said to him, ‘How can these things be?’ 10Jesus answered him, ‘Are you a teacher of Israel, and yet you do not understand these things?

11 ‘Very truly, I tell you, we speak of what we know and testify to what we have seen; yet you do not receive our testimony. 12If I have told you about earthly things and you do not believe, how can you believe if I tell you about heavenly things? 13No one has ascended into heaven except the one who descended from heaven, the Son of Man.14And just as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, 15that whoever believes in him may have eternal life.
