The purpose of divine Principle, God, is to express itself. Man lives in accordance with this divine purpose, his existence evidencing the eternal unfolding of divine Principle. Man is the complete, full unfoldment of the nature of God—a divine necessity—the loved of Love, the marvelous expression of ever-active Mind. Could there be Mind without ideas, or could there be an isolated, wandering thought devoid of presence and of power, cut off from source or sustenance? The great reality of being is Principle, forever content in its infinite self-containment, seeing everything that is made and beholding it as "very good."
Man lives for the glory of God. His infinite progression in the universe of Mind is in accordance with the will of God and is under the direction of Mind. Man's Father-Mother God is ceaselessly active in his behalf. God pours forth His riches upon man, who in bearing witness to Him necessarily manifests His abundance of good. Jesus, ever conscious of the supremacy of good, spoke thus to Pilate (John 18:37): "To this end was I born, and for this cause came I into the world, that I should bear witness unto the truth." Jesus knew that we of our own selves can do nothing; that all things true are done for the glorification of God rather than the exaltation of personality. Knowing this, he could hold his peace before the hatred of mortal mind and bear perfect witness to the supreme power of Principle, Love.
Evil is without Principle, hence without purpose; without Life, hence without existence. Mary Baker Eddy states in the Christian Science textbook, "Science and Health with Key to the Scriptures" (p. 405), "This is sin's necessity,—to destroy itself." Even in the suppositional realm of belief we find evil, when claiming to become more imperative in its demands, rising only to its zenith of self-destruction. A lie is ever the opposite of Truth, a negation from the outset. Hence its suppositional qualities and modes are not the ways of goodness. Goodness leads to Life, evil leads to death; in goodness is strength, in evil is weakness; goodness is real, evil is unreal.
