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."
So they came to John, and they said, "That one that you bore witness to, you said 'the Lamb of God and all.' He's baptizing now and everyone is going to Him."
