John 3:4 BBE

²  He 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.

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

⁴  Nicodemus 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?

⁵  Jesus 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.

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