john 3:3 Jesus replied, "I assure you, unless you are born again, you can never see the Kingdom of God."
Nonsense.
I'd go even father and cite Mark 16:16:
"Whoever believes and is baptized shall be saved, but those who do not shall be damned".
Unless one is born again (with water), in addition to belief, one is lost. Jews, Muslims, Buddhists cannot fathom this unless they first believe and follow through.
