John 3:2-13

²he came to him by night, and said to him, Rabbi, we know that thou art come a teacher from God, for none can do these signs that thou doest unless God be with him.

³Jesus answered and said to him, Verily, verily, I say unto thee, Except any one be born anew he cannot see the kingdom of God.

⁴Nicodemus says to him, How can a man be born being old? can he enter a second time into the womb of his mother and be born?

⁵Jesus answered, Verily, verily, I say unto thee, Except any one be born of water and of Spirit, he cannot enter into the kingdom of God.

⁶That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.

⁷Do not wonder that I said to thee, It is needful that ye should be born anew.

⁸The wind blows where it will, and thou hearest its voice, but knowest not whence it comes and where it goes: thus is every one that is born of the Spirit.

⁹Nicodemus answered and said to him, How can these things be?

¹⁰Jesus answered and said to him, Thou art the teacher of Israel and knowest not these things!

¹¹Verily, verily, I say unto thee, We speak that which we know, and we bear witness of that which we have seen, and ye receive not our witness.

¹²If I have said the earthly things to you, and ye believe not, how, if I say the heavenly things to you, will ye believe?

¹³And no one has gone up into heaven, save he who came down out of heaven, the Son of man who is in heaven.
