Everyone will agree that something is animating him, giving him life and activity. Even when he is asleep, the normal action of his body continues. Christian Science shows that the flesh cannot act of itself, cannot govern itself, cannot get itself into trouble or take itself out of trouble. Thought alone animates the individual, and it is through thought that Science reaches the body and heals it when it is upset.
Mary Baker Eddy says in "Science and Health with Key to the Scriptures" (p. 400): "When we remove disease by addressing the disturbed mind, giving no heed to the body, we prove that thought alone creates the suffering. Mortal mind rules all that is mortal." Later in the paragraph is this instructive sentence: "The action of so-called mortal mind must be destroyed by the divine Mind to bring out the harmony of being."
"But how many minds are there?" one might ask. The answer of scientific theology is this: Only one. And although the Scientist does not ignore the enigma of a material or mortal mind and works to regenerate the human mind, he acknowledges as real only the absolute divine Mind. He refuses to believe in the validity of a mind opposed to God, a carnal mentality, and this refusal helps him to overcome sin and disease, deformity, deterioration, constriction, and all the other ills of the flesh which are the effects of a false animating force.
