John 3:4-6

⁴Nicodemus saith 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 again?

⁵Jesus answered: Amen, amen I say to thee, unless a man be born again of water and the Holy Ghost, he cannot enter into the kingdom of God.

⁶That which is born of the flesh, is flesh; and that which is born of the Spirit, is spirit.
