John 3

1Now there was a man of the Pharisees named Nicodemus, a ruler of the Jews.

2The 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."

3Jesus answered him, "Most certainly, 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."
