2This man came to Him by night and said to Him, “Rabbi, we know that You have come from God as a teacher; for no one can do these signs that You do unless God is with him.”
3Jesus answered and said to him, “Most assuredly I say to you, unless one is born again, he cannot see the kingdom of God.”
4Nicodemus said to Him, “How can a man be born, being old? Can he enter a second time into his mother's womb and be born?”
5Jesus answered, “Most assuredly I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.
6That which is born of the flesh is flesh, and that which is born of the Spirit is spirit.
7Do not marvel that I said to you, ‘You must be born again.’
8The wind blows where it wills, and you hear its sound, but you do not know from where it comes and where it goes. So is everyone who has been born of the Spirit.”
9Nicodemus answered and said to Him, “How can these things be?”
