John 3:1-13

Now there was a man of the Pharisees, named Nicodemus, a ruler of the Jews: the same came unto him by night, and said to him, Rabbi, we know that thou art a teacher come from God; for no one can do these signs that thou doest, except God be with him. Jesus answered and said unto him, Verily, verily, I say unto thee, Except one be born anew, he cannot see the kingdom of God. Nicodemus saith unto 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? Jesus answered, Verily, verily, I say unto thee, Except one be born of water and the Spirit, he cannot enter into the kingdom of God. That which is born of the flesh is flesh; and that which is born of the Spirit is spirit. Marvel not that I said unto thee, Ye must be born anew. The wind bloweth where it will, and thou hearest the voice thereof, but knowest not whence it cometh, and whither it goeth: so is every one that is born of the Spirit. Nicodemus answered and said unto him, How can these things be? Jesus answered and said unto him, Art thou the teacher of Israel, and understandest not these things? Verily, verily, I say unto thee, We speak that which we know, and bear witness of that which we have seen; and ye receive not our witness. If I told you earthly things and ye believe not, how shall ye believe if I tell you heavenly things? And no one hath ascended into heaven, but he that descended out of heaven, even the Son of man, who is in heaven.
