"No man can illuminate his own soul; all understanding must come from above. Here the metaphor is changed, and God is compared to the sun in the firmament of heaven, that gives light to all the planets and their inhabitants. "God said, Let there be light; and there was light; "by that light the eye of man was enabled to behold the various works of God, and the beauties of creation: so, when God speaks light into the dark heart of man, he not only beholds his own deformity and need of the salvation of God, but he beholds the "light of the glory of God in the face of Jesus Christ;" "God, in Christ, reconciling the world to himself." "In thy light shall we see light." This is literally true, both in a spiritual and philosophical sense." Adam Clarke
