1 There was a person of the Pharisees, Nicodemus his name, a ruler of the Judeans.
2 This one came to Him at night, and said to Him, “Rabbi, we know that You have come from God as a teacher. For no one is able to do these signs, unless the God were with him.”
3 Jesus answered and said to him, “Truly, truly, I say to you, if someone is not born anew, he is not able to perceive the Kingdom of the God.”
4 Nicodemus says to Him, “How is a person able to be born, being old? He is not able to go into the inside of the mother of his, and be born.”
5 Jesus answered: “Truly, truly, I say to you, if someone is not born forth from water and Spirit, he cannot enter into the Kingdom of God.
6 What is born forth from the flesh is flesh, and what is born forth from Spirit is spirit.
7 Do not be amazed that I say to you, ‘It is necessary that you be born anew.’
8 The wind blows where it wills, and you hear the sound of it, but you do not know from where it comes or where it goes. So is everyone who is born out of the Spirit.”
9 Nicodemus answered and said to Him, “How can these things happen?”
10 Jesus answered and said to him, “Are you the teacher of Israel, and do not understand these things?
11 Truly, truly, I say to you, that what We know We speak, and what to We see We testify. You all do not receive even Our testimony?
12 If you all do not believe the earthly things that I say to you all, how will you all believe the heavenly things if I would say them to you all?
13 Also, no one has ascended into the Heaven, except the One having descended from the Heaven, the Son of Man.
14 And just as Moses raised up the snake in the desert, so it is necessary that the Son of Man be raised up,
15 so that everyone believing* in Him should have eternal life.
16 For God so loved the world that He gave the only begotten Son, so that everyone believing in Him should not perish but should have eternal life.
17 For God did not send the Son into the world so that He should judge the world, but so that He should rescue the world through Him.
18 The one believing in Him is not judged. But the one not believing is already judged, because he believed not in the name of the only begotten Son of God.
19 And this is the judgement: that the light came into the world, and the people loved the darkness more than the light, for the works of theirs were evil.
20 Indeed, everyone who practices bad things hates the light and does not come to the light, so that the works of his not be examined.
21 But the one doing the truth comes to the light, so that the works of his be revealed, that by God they are worked.
