Yeshua Jesus, John, & Nicodemus: A Master's Class in Cosmology 

In the beginning was the Word, and the Word was with God, and the Word was God. The same was in the beginning with God. All things were made by him; and without him was not anything made that was made. In him was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not. There was a man sent from God, whose name was John. The same came for a witness, to bear witness of the Light, that all men through him might believe. He was not that Light, but was sent to bear witness of that Light. That was the true Light, which lighteth every man that cometh into the world. He was in the world, and the world was made by him, and the world knew him not. He came unto his own, and his own received him not. But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name: Which were born, not of blood, nor of the will of the flesh, nor of the will of man, but of God. And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.
(Joh 1:1-14)

Take note of the bolded words. Christianity reads this passage and applies Spirituality to it, which is certainly the main point. Yet the construction of this passage is specifically copying Genesis chapter1!  And Western Evangelical Christianity has interpreted Gen 1-2 as a physical creation narrative; but is it? Let's look at them side by side and compare the two with bolded words:

"A man came, one sent from God, and his name was John. He came as a witness, to testify about the Light, so that all might believe through him. He was not the Light, but he came to testify about the Light: 

This was the true Light that, coming into the world, enlightens every person. He was in the world, and the world came into being through Him, and yet the world did not know Him. He came to His own, and His own people did not accept Him. But as many as received Him, to them He gave the right to become children of God, to those who believe in His name, who were born, not of blood, nor of the will of the flesh, nor of the will of a man, but of God. And the Word became flesh, and dwelt among us; and we saw His glory, glory as of the only Son from the Father, full of grace and truth."

(Joh 1:6-14)

Here we see John explaining the theology of John the baptiser's preaching. This is an introductory to the Pharisees and other cognoscenti that the world, as they imagined it, was about to be broached by the revelation of one who is not just flesh and blood, but from the spirit world they have minimized. At the time of Yeshua, Judaism had broken into sects, Pharisees and Sadducees on the religious side, along with the Greeks who were "secular" and the Romans were-- well-- Romans!  Yeshua Jesus was going to "Let there be Light" over all of them! the Apostle John was enlightened with this message.
