2This man came to Jesus by night, and said to Him, “Rabbi, we know that You have come from God as a teacher, for no one can do these signs that You do unless God is with him.”
3Jesus answered and told him, “Most assuredly, I tell you, unless one is born again, that person can’t see the kingdom of God.”
4Nicodemus asked Him, “How can a man be born when he is old? He can’t go back into his mother’s womb and be born, can he?”
5Jesus answered, “Most assuredly, I tell you, unless one is born of water and the Spirit, that one can’t enter the Kingdom of God.
6That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.
7Don’t marvel that I told you, ‘You must be born again.’
8The wind blows where it wants to, and you hear its sound, but can’t tell where it comes from and where it goes. So is everyone who is born of the Spirit.”
9Nicodemus asked Him, “How can these things be?”
10“Are you Israel’s teacher,” asked Jesus, “and yet you don’t understand these things?
11Most assuredly, I tell you, we speak what we know and testify what we have seen, and you don’t receive our witness.
12If I have told you earthly things and you don’t believe, how will you believe if I tell you heavenly things?
13No one has ever gone up into Heaven except the one who came from Heaven — the Son of Man.
14Just as Moses lifted up the snake in the desert, so the Son of Man must be lifted up,
15that everyone who believes in Him should not die, but have eternal life.
16For God so sincerely loved the world that He gave His only born Son, that whoever believes in Him should not perish, but have everlasting life.
17For God didn’t send His Son into the world to condemn the world, but to save the world through Him.
