Now there was a man of the Pharisees, whose name was Nicodemus, a ruler of the Jews. This man came to Him by night and said to him, "Rabbi, we know that Thou art come a Teacher from God; for no one is able to do these signs which Thou art doing, unless God be with him." Jesus answered and said to him, "Verily, verily, I say to thee, unless one be born from above, he cannot see the Kingdom of God." Nicodemus 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?"
Jesus answered, "Verily, verily I say to thee, unless one be born of water and of the Spirit, he cannot enter into the Kingdom of God. That which hath been born of the flesh is flesh; and that which hath been born of the Spirit is spirit. Do not wonder that I said to thee, it is necessary for you to be born from above. The wind bloweth where it will, and thou hearest the sound thereof, but thou knowest not whence it cometh and whither it goeth: so is every one that hath been born of the Spirit."
Nicodemus answered and said to Him, "How can these things be?" Jesus answered and said to him, "Art thou the teacher of Israel, and understandest not these things? Verily, verily, I say to thee. We speak that which We know, and testify that which We have seen; and ye receive not Our testimony. If I told you earthly things and ye believe not, how shall ye believe if I tell you heavenly things? And no one hath ascended into heaven, but He who descended out of heaven, the Son of man (Who is in heaven). And as Moses lifted up the serpent in the wilderness, so it is necessary that the Son of Man be lifted up, that every one who believeth in Him may have everlasting life.
For God so loved the world, that He gave His only begotten Son, that every one who believeth in Him should not perish, but have everlasting life. For God sent not the Son into the world to judge the world, but that the world might be saved through Him.
He that believeth in Him is not judged; he that believeth not hath been judged already, because he hath not believed in the name of the only begotten Son of God. Now this is the judgment, that the Light hath come into the world, and men loved the darkness rather than the Light; for their works were evil. For every one that doeth evil hateth the Light, and cometh not to the Light, that his works may not be exposed. But he that doeth the truth cometh to the Light, that his works may be made manifest, because they have been wrought in God."
