Gospel according to John

Now there was a man of the Pharisees named Nicodemus, a ruler of the Jews.

The same came to him by night, and said to him, "Rabbi, we know that you are a teacher come from God, for no one can do these signs that you do, unless God is with him."

Jesus answered him, "Most assuredly, I tell you, unless one is born anew, he can't see the Kingdom of God."

Nicodemus said to him, "How can a man be born when he is old? Can he enter a second time into his mother's womb, and be born?"

Jesus answered, "Most assuredly I tell you, unless one is born of water and spirit, he can't enter into the Kingdom of God!
