Each of us has a basic purpose for existing. It is to be what God created man to be, His witness. In her work "No and Yes," Mrs. Eddy writes (p. 17), "Man is the climax of creation; and God is not without an ever-present witness, testifying: of Himself."
The Bible records God's explicit mandate to man (Gen. 1:28): "Be fruitful, and multiply, and replenish the earth, and subdue it: and have dominion over the fish of the sea, and over the fowl of the air, and over every living thing that moveth upon the earth." The dominion which God commands man to show forth in order to fulfill his purpose as God's "ever-present witness" is God-created and God-sustained. Mrs. Eddy brings this important point into sharp focus when she states (Science and Health,p. 516), "Man, made in His likeness, possesses and reflects God's dominion over all the earth." If man originated fruitfulness and dominion, man would not be reflection but creator, and God would not be the supreme and only creator. On page 475 of Science and Health, after bringing out that the man of God's creating is not physique, Mrs. Eddy describes man, the incorporeal reflection of God, as "that which possesses no life, intelligence, nor creative power of his own, but reflects spiritually all that belongs to his Maker."
Mortals, until they are instructed by Christian Science, are apt to try to demonstrate the dominion of God from the standpoint that man is a personal doer, thinker, and creator, a self -created and self-actuated entity. This approach fails because it is contrary to the spiritual fact that God alone is all-acting, all-knowing; He is the only creator, the only self-existent.
