Now there was a man of the Prushim, named Nakdimon, a leader of the Jews; this man came to The Rabbi by night and said to Him, "Rabbi, we know that You have come from G-d as a teacher; for no one can do these signs that You do unless G-d is with him."
The Rabbi answered and said to him, "Amen, amen, I say to you, unless one is born again he cannot see the kingdom of G-d."
Nakdimon said to Him, "How can a man be born when he is old? He cannot enter a second time into his mother's womb and be born, can he?"
The Rabbi answered, "Amen, amen, I say to you, unless one is born of water and the Spirit he cannot enter into the kingdom of G-d. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. Do not be amazed that I said to you, 'You must be born again.' The wind blows where it wishes and you hear the sound of it, but do not know where it comes from and where it is going; so is everyone who is born of the Spirit."
Nakdimon said to Him, "How can these things be?"
The Rabbi answered and said to him, "Are you the teacher of Israel and do not understand these things? Amen, amen, I say to you, we speak of what we know and testify of what we have seen, and you do not accept our testimony. If I told you earthly things and you do not believe, how will you believe if I tell you heavenly things? No one has ascended into heaven, but He who descended from heaven: the Son of Man. As Moses lifted up the serpent in the wilderness, even so must the Son of Man be lifted up; so that whoever believes will in Him have eternal life.
For G-d loved the world in this manner: He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life. For G-d did not send the Son into the world to judge the world, but that the world might be saved through Him. He who believes in Him is not judged; he who does not believe has been judged already, because he has not believed in the name of the only begotten Son of G-d.
This is the judgment, that the Light has come into the world, and men loved the darkness rather than the Light, for their deeds were evil. For everyone who does evil hates the Light, and does not come to the Light for fear that his deeds will be exposed. But he who practices the truth comes to the Light, so that his deeds may be manifested as having been wrought in G-d."
This is the life of the Rabbi.
