Action is an important factor in everyone's experience. Existence is never static and inanimate; it abounds in activity. Physical science avers that even material things, which to the eye appear solid and motionless, are in a state of ceaseless vibration, a form of action.
Christian Science differentiates between the material conception of life, man, and action, and the spiritual, or true, sense of Life, action, and man. It teaches that what is purely material action is the temporary, unintelligent action of mortal mind, identified in materially motivated mortals, creatures, and things. Such action is no more real action than mortal mind is real Mind. Mortal mind and material action are coincident.
Mary Baker Eddy places God in apposition to omniaction. In other words, she defines God in terms of action in her revealing definition of "good." On page 587 of "Science and Health with Key to the Scriptures" she says, "God; Spirit; omnipotence; omniscience; omnipresence; omniaction." God as omniaction is the sum of all real action. Scientifically there is no action but His. Infinity is filled with this all-acting Mind, and its Mind-animated identities and ideas, all expressing the tireless, intelligent, healthful activity of God.
