From glory to glory

Now the earth was formless and empty, darkness was over the surface of the deep, and the Spirit of God was hovering over the waters (Genesis 1v2)

Thus, the Spirit had been inserted into the earthly realm from the heavenly realm, proceeding from the Father and the Son, evidently at the precise moment of the act of creation. The creation does not exist apart from the presence of the moving Spirit within her. God never needs to 'enter' the creation; by His Spirit He has been present within her from the very beginning. 

Then God said, 'Let there be light.' The only source for that light is the Spirit Himself. When God appears later on in the Bible, He is surrounded by the glory, which is associated with the Spirit. Indeed, His glory hovers over Israel in the pillar of cloud and fire. Thus, the initial light came from the Spirit. Light is energy, fire; so no fire is brought into the earth from heaven. Fire transforms things, and so begins the transfiguration of the earth, from glory to glory.
