John 3
1 Ref Now there was a man of the Pharisees named Nicodemus, a ruler of the Jews.
2 Ref 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."
3 Ref Jesus answered him, "Most assuredly, I tell you, unless one is born anew,{The word translated "anew" here and in John 3:7 (anothen) also means "again" and "from above".} he can't see the Kingdom of God."
4 Ref 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?"
5 Ref Jesus answered, "Most assuredly I tell you, unless one is born of water and spirit, he can't enter into the Kingdom of God!
6 Ref That which is born of the flesh is flesh. That which is born of the Spirit is spirit.
