John 3:1-13 King James Version (KJV)
3 There was a man of the Pharisees, named Nicodemus, a ruler of the Jews:
2 The same came to Jesus by night, and said unto him, Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him.
3 Jesus answered and said unto him, Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
4 Nicodemus saith unto him, How can a man be born when he is old? can he enter the second time into his mother's womb, and be born?
5 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.
6 That which is born of the flesh is flesh; and that which is born of the Spirit is spirit.
7 Marvel not that I said unto thee, Ye must be born again.
8 The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
9 Nicodemus answered and said unto him, How can these things be?
10 Jesus answered and said unto him, Art thou a master of Israel, and knowest not these things?
11 Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness.
12 If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things?
13 And no man hath ascended up to heaven, but he that came down from heaven, even the Son of man which is in heaven.
John 3:1-13 Amplified Bible, Classic Edition (AMPC)
3 Now there was a certain man among the Pharisees named Nicodemus, a ruler (a leader, an authority) among the Jews,
2 Who came to Jesus at night and said to Him, Rabbi, we know and are certain that You have come from God [as] a Teacher; for no one can do these signs (these wonderworks, these miracles—and produce the proofs) that You do unless God is with him.
3 Jesus answered him, I assure you, most solemnly I tell you, that unless a person is born again (anew, from above), he cannot ever see (know, be acquainted with, and experience) the kingdom of God.
4 Nicodemus said to Him, How can a man be born when he is old? Can he enter his mother’s womb again and be born?
5 Jesus answered, I assure you, most solemnly I tell you, unless a man is born of water and [[a]even] the Spirit, he cannot [ever] enter the kingdom of God.
6 What is born of [from] the flesh is flesh [of the physical is physical]; and what is born of the Spirit is spirit.
7 Marvel not [do not be surprised, astonished] at My telling you, You must all be born anew (from above).
8 The wind blows (breathes) where it wills; and though you hear its sound, yet you neither know where it comes from nor where it is going. So it is with everyone who is born of the Spirit.
9 Nicodemus answered by asking, How can all this be possible?
10 Jesus replied, Are you the teacher of Israel, and yet do not know nor understand these things? [Are they strange to you?]
11 I assure you, most solemnly I tell you, We speak only of what we know [we know absolutely what we are talking about]; we have actually seen what we are testifying to [we were eyewitnesses of it]. And still you do not receive our testimony [you reject and refuse our evidence—that of Myself and of all those who are born of the Spirit].
12 If I have told you of things that happen right here on the earth and yet none of you believes Me, how can you believe (trust Me, adhere to Me, rely on Me) if I tell you of heavenly things?
13 And yet no one has ever gone up to heaven, but there is One Who has come down from heaven—the Son of Man [Himself], [b]Who is (dwells, has His home) in heaven.
