John 3: 5, 6, 12, 15 
Verily, verily, I say unto thee,
except a man be born of water
and of the Spirit, he cannot enter
into the kingdom of God.
That which is born of the flesh is
flesh, and that which is born of the
Spirit is spirit.
If I have told you earthly things
and you do not believe, how will
you believe if I tell you heavenly
things?
That whoever believes in Him should
not perish but have eternal life.
