Christ the true Light

Golden cross with Greek words Light and Life on it

It is important to make clear that the first light of creation that filled the universe is not the light that the Gospel of John and other New Testament books talk about in connection with Christ. Created light was made by the Word of God.

The gospel begins with words that do bring to mind the first chapter of the Bible, Genesis:

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 any thing 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.
John 1:1-14 KJVA

Genesis tells that the first word of Creation where "Let there be light!"Genesis 1:3

And indeed, the Big Bang was quickly followed by brilliant light as things began to happen in extreme heat and energy and photons, those amazing wave-particles, began to fly around at the speed of light.

But the Gospel of John does not refer to created light that fills the universe and makes us wonder what it is. The True light of Christ is not made of photons.

In him was life; and the life was the light of men.
Apostle Paul writes about the Light where Christ dwells

I give thee charge in the sight of God, who quickeneth all things, and before Christ Jesus, who before Pontius Pilate witnessed a good confession; That thou keep this commandment without spot, unrebukeable, until the appearing of our Lord Jesus Christ:

Which in his times he shall shew, who is the blessed and only Potentate, the King of kings, and Lord of lords; Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see: to whom be honour and power everlasting.
Amen.1 Timothy 6:13-16 KJVA

Who only hath immortality, dwelling in the light which no man can approach unto; whom no man hath seen, nor can see.
