John 3:2-15

²He came to Jesus by night and said to him, Rabbi, we are certain that you have come from God as a teacher, because no man would be able to do these signs which you do if God was not with him.

³Jesus said to him, Truly, I say to you, Without a new birth no man is able to see the kingdom of God.

⁴Nicodemus said to him, How is it possible for a man to be given birth when he is old? Is he able to go into his mother's body a second time and come to birth again?

⁵Jesus said in answer, Truly, I say to you, If a man's birth is not from water and from the Spirit, it is not possible for him to go into the kingdom of God.

⁶That which has birth from the flesh is flesh, and that which has birth from the Spirit is spirit.

⁷Do not be surprised that I say to you, It is necessary for you to have a second birth.

⁸The wind goes where its pleasure takes it, and the sound of it comes to your ears, but you are unable to say where it comes from and where it goes: so it is with everyone whose birth is from the Spirit.

⁹And Nicodemus said to him, How is it possible for these things to be?

¹⁰And Jesus, answering, said, Are you the teacher of Israel and have no knowledge of these things?

¹¹Truly, I say to you, We say that of which we have knowledge; we give witness of what we have seen; and you do not take our witness to be true.

¹²If you have no belief when my words are about the things of earth, how will you have belief if my words are about the things of heaven?

¹³And no one has ever gone up to heaven but he who came down from heaven, the Son of man.

¹⁴As the snake was lifted up by Moses in the waste land, even so it is necessary for the Son of man to be lifted up:

¹⁵So that whoever has faith may have in him eternal life.
