There is a beautiful passage in the Psalms which says "In thy light do we see light" (Ps. 36:9).
Light is one of the richest metaphors in the Scriptures, possessing multiple layers of meaning. On the one hand, it is a powerful symbol for the incomprehensible splendor of God's essence. "God is light," St. John tells us (1 John 1:5), and Paul says "God dwells in unapproachable light" (1 Tim. 6:16). "The Lord God is a sun and shield," says the Psalmist (Ps. 84:11).
