John 3:6-12 New Revised Standard Version (NRSV)
6 What is born of the flesh is flesh, and what is born of the Spirit is spirit.[a] 7 Do not be astonished that I said to you, ‘You[b] must be born from above.’[c] 8 The wind[d] 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.” 9 Nicodemus said to him, “How can these things be?” 10 Jesus 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[e] do not receive our testimony. 12 If I have told you about earthly things and you do not believe, how can you believe if I tell you about heavenly things?
