Are there not different kinds of light?

First, there is light which was never "made", nor ever "came into existence", but always was, is it not an attribute of God?

I John 1:5 This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all.

Secondly, was there not a light made by the LORD in the very beginning?

Genesis 1:4 And God said, Let there be light: and there was light. 

Was that not three days before the sun, moon, and stars, and therefore it may have been spiritual light?

Third, did not the LORD make physical light on the fourth day?

Genesis 1:14 And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for seasons, and for days, and years:

 15 And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so.

 16 And God made two great lights; the greater light to rule the day, and the lesser light to rule the night: he made the stars also.

 17 And God set them in the firmament of the heaven to give light upon the earth,

 18 And to rule over the day and over the night, and to divide the light from the darkness: and God saw that it was good.

Regarding that spiritual light, can it not be dark?

Matthew 6:23 But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be darkness, how great is that darkness! 

However, can it not be the other way?

Matthew 5:16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven. 

So is that spiritual light that which the Son of God lights every man that cometh into the world, since he created that light?

John 1:9 That was the true Light, which lighteth every man that cometh into the world.

And since Jesus is truth, then he that doeth truth cometh to the light, when the Father draws that person?

John 3:21 But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God.

Then when God was manifest in the flesh, did not that attribute of God, eternal light, come into the world in a body?

Then someday, will it not be?

Revelation 21:23 And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb is the light thereof.
