I John 1:5
God is light, in Him there is no darkness at all; no shadow of turning, pure light.
3:2
Now we are children of God, and what we will be has not yet been made known. But we know that when He appears, we shall be like Him, for we shall see Him as He is.
4:12a
No one has ever seen God . . .
When Moses spent time with God on the mountain, and actually saw God's "back," he came down from that mountain glowing, so that he had to wear a veil over his face.
God is pure, unadulterated light, with no "shadow of turning." Our eyes are incapable, unable to "see" light, we need shadows to define what we're looking at; pure light would be a glare, that would burn our eyes to look at, like looking into the Sun, which is a "light holder" reflecting a small portion of God's glory. But when Jesus returns, and our bodies are "changed," then we'll have "new eyes" and will be able to behold Him, see Him as He is.
