John 3:2-9

²This man came to Jesus by night, and said to him: Rabbi, we know that thou art come a teacher from God; for no man can do these signs which thou dost, unless God be with him.

³Jesus answered, and said to him: Amen, amen I say to thee, unless a man be born again, he cannot see the kingdom of God.

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.

⁷Wonder not, that I said to thee, you must be born again.

⁸The Spirit breatheth where he will; and thou hearest his voice, but thou knowest not whence he cometh, and whither he goeth: so is every one that is born of the Spirit.

⁹Nicodemus answered, and said to him: How can these things be done?
