2The same went to Jesus at night and said to Him, “Rabbi, we know that you have come as a teacher from God, because no one can do these signs that you do unless God is with him.”
3Jesus answered and said to him, “Most assuredly I say to you, unless someone is begotten from Above, he is not able to see the kingdom of God.”
4Nicodemus says to Him: “How can a man be begotten, being old? He can't enter his mother's womb a second time and be born, can he?”
5Jesus answered: “Most assuredly I say to you, unless someone is begotten by water and Spirit he is not able to enter the kingdom of God.
6That which has been begotten by the flesh is flesh, and that which has been begotten by the Spirit is spirit.
7Do not be perplexed that I said to you, ‘You (pl) need to be begotten from Above.’
8The wind blows where it wishes, and you (sg) hear its sound, but you do not know where it comes from or where it goes. So it is with everyone who has been begotten by the Spirit.”
9Nicodemus answered and said to Him, “How can these things be?”
10Jesus answered and said to Him: “You are the teacher of Israel, yet you do not understand these things?
11Most assuredly I say to you, we speak what we know and testify to what we have seen, but you (pl) do not receive our testimony.
12If I have told you earthly things and you do not believe, how will you believe if I should tell you the heavenly?
13No one has gone up into Heaven except the One who came down out of Heaven —the Son of the Man, who is in Heaven.
14Also, just as Moses lifted up the snake in the wilderness, just so the Son of the Man must be lifted up,
15so that everyone who believes into Him should not be wasted, but should have eternal life.
16Because God loved the world so much that He gave His only begotten Son, so that everyone who believes into Him should not be wasted, but should have eternal life.
17For God did not send His Son into the world in order to condemn the world, but so that the world might be saved through Him.
