It is possible to heal the sick in Christian Science only because sickness is unreal to begin with and health is the continuing fact of being, past, present, and future.
"If disease is as real as health, and is itself a state of being, and yet is arrayed against being, then Mind, or God, does not meddle with it," writes Mrs. Eddy (No and Yes, p. 5). Christian Science does not grapple with a genuinely diseased condition of matter and change it into a healthy condition of matter. It reveals a genuinely perfect, wholly spiritual state of being; and the light of this revelation dispels the mindless darkness we have come to term disease.
He who would utilize safely and soundly the might of Christian Science must keep this truism in mind, for it is by working from this spiritual standpoint alone that one gains genuine Christian Science healing. Otherwise, the would-be Christian Scientist runs the risk of believing that Christian Science is merely one more way, though possibly a superior one, by which to change physical discord into physical harmony, to supplant poverty with material abundance, and to improve an erring material universe until it eventually becomes an unerring material universe.
