With our eyes we can look at the sun only for a brief moment of time because its light can blind us. We cannot see God's glory which is the refulgence of being with our eyes or imagination because God is Spirit.

But by means of our intelligent spirit we see beyond the visible. We perceive God's purity or holiness in the whiteness of snow, his beauty in the form/colors of a flower and his glory in the starry heavens. Through the visible creation we form the idea that God is most beautiful.

The Book of Wisdom further transfigures our understanding of God as the Spiritual Light as follows:

"God's Wisdom" is a spirit intelligent, holy, unique,
Manifold, subtle, agile, clear, unstained, certain,
Not baneful, loving the good, keen, unhampered, beneficent, kindly,
Firm, secure, tranquil, all-powerful, all-seeing,
And pervading all spirits, though they be intelligent, pure and very subtle. ...

For she is an aura of the might of God and a pure effusion of the glory of the Almighty; therefore nought that is sullied enters into her.
For she is the refulgence of eternal light, the spotless mirror of the power of God, the image of his goodness.
And she, who is one, can do all things, and renews everything while herself perduring; ...

For she is fairer than the sun and surpasses every constellation of the stars. Compared to light, she takes precedence; for that, indeed, night supplants, but wickedness prevails not over Wisdom." (Ws 7: 22,25-27,29-30)

The beautiful and insightful description of the glory God's spirit, however, falls far short of the reality because--

God "dwells in unapproachable light,...
[which] no human being
has seen or can see." (1 Tim 6:16)

Immortal, Invisible, God Only Wise

Immortal, invisible, God only wise,
in light inaccessible hid from our eyes,
most blessed, most glorious, the Ancient of Days,
almighty, victorious, thy great name we praise.

Thou reignest in glory; thou dwellest in light;
thine angels adore thee, all veiling their sight;
all laud we would render: O help us to see
'tis only the splendor of light hideth thee.
