John 3:1 "There was a man of the Pharisees, named Nicodemus, a ruler of the Jews:"

John 3:2 "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."

John 3:3 "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."

John 3:4 "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?"

John 3:5 "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."

John 3:6 "That which is born of the flesh is flesh; and that which is born of the Spirit is spirit."

John 3:7 "Marvel not that I said unto thee, Ye must be born again."

John 3:8 "The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell from whence it cometh, and whither it goeth: so is every one that is born of the Spirit."

John 3:9 "Nicodemus answered and said unto Him, "How can these things be?"

John 3:10 "Jesus answered and said unto him, "Art thou a master of Israel, and knowest not these things?"

Jesus then reverses the question back to Nicodemus; "Are you not a teacher to Israel, and you do not know these things?" This is the same reason that so many fall short in their teaching even today. There are many that claim to be teachers of God's Word, yet they peddle their wears of false teaching for many different reasons. If you have the understanding of God's Word, that is a gift from God, then that knowledge belongs to God. Jesus is telling Nicodemus, you claim to be a teacher, and you don't even know this?

Nicodemus didn't know the Word because he didn't study the word. Nicodemus studied the traditions that were accepted by the religious community of that day. In fact, he was one of the spiritual leaders of that community.

John 3:11 "Verily, Verily, I say unto thee, We speak that we do know, and testify that we have seen; and ye receive not our witness."

Truly, Truly Jesus is saying to him, I'm sharing these things that I know to be true, and it appears that you are questioning our witness to those words.

John 3:12 "If I have told you earthly things, and ye believe not, how shall ye believe, if I tell you of heavenly things?"

Jesus is telling Nicodemus, now that I have told you where and how the soul has come into the flesh and departs to the Father; these things that are fleshly and you still can not understand. There is then no way that you can understand the revelation that Christ brought of the spiritual realm without the Spirit of God. It is impossible.

John 3:13 "And no man hath ascended up to heaven, but He That came down from heaven, even the Son of man Which is in heaven."

God's only begotten Son Jesus, (God Himself in a flesh and blood body) also did that, when he came to live with us for a short while, and then sacrifice His physical life, shedding His sin free blood to cover the sins of mankind, for all of us who believe in Him, repent of our sins, and by our own free will, invite His Holy Spirit into our heart to cleanse it.

We, our souls, were all created in the beginning as angelic spirit beings with celestial bodies, prior to the creation of the earth and lived in that 1st earth age in those celestial, angelic bodies, but since God destroyed that 1st earth age because of Lucifer's overthrow attempt we have since been coming the this restructured earth to live in terrestrial, animal bodies, but when we go back to heaven we will again be placed in celestial bodies.
