Jesus answered, 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.
John 3:6That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
1 John 5:4For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.
