Throughout the Scriptures good and evil are often metaphorically represented by light and darkness. It is clear that where light is, darkness is not; so it is encouraging to remember that the first command of God recorded in the Bible was, "Let there be light." Since this command was never rescinded, reversed, or altered, it is plain that this light is still present, despite the arguments of error that darkness has replaced it. Mary Baker Eddy writes in "Science and Health with Key to the Scriptures" (p. 546), "The great spiritual facts of being, like rays of light, shine in the darkness, though the darkness, comprehending them not, may deny their reality."
God's radiant presence can have no conflict with darkness. It is all-inclusive, all-pervading. Only to material sense can darkness seem real, so "the power of darkness" spoken of in the Bible is a figment of material belief. This must be so, for God is the only power. Yet how little do we as yet understand this grand truth, and how meager is humanity's acknowledgment that "the Lord God omnipotent reigneth"!
Since man was made in God's image, he lives and moves in spiritual light. He cannot be plunged into gloom, for the allness of God precludes the possibility of His absence. When we see that in our true selfhood we are ideas, reflections of divine Love, we realize that no matter what seeming darkness may have engulfed us it is but a false sense, a belief in an existence apart from our source—an impossibility.
