John 3:4-6
4
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
Jesus answered, "Most certainly I tell you, unless one is born of water and spirit, he can't enter into the Kingdom of God!
6
That which is born of the flesh is flesh. That which is born of the Spirit is Spirit.
