It was into the darkness of such a disappointed world that the light of Christian Science came, showing not only the true nature of health, but the way to secure it. When Mrs. Eddy states in "Science and Health with Key to the Scriptures" (p. 120), "Health is not a condition of matter, but of Mind; nor can the material senses bear reliable testimony on the subject of health," she immediately places health where it belongs, and opens the way for all to understand and demonstrate it. Immediately, thought is turned away from matter to God, divine Mind. Finding that health belongs to divine Mind, the infinite God, it is readily seen that it must always be found therein, existing as a divinely mental attribute. Every child of God, therefore, must reflect it, and can never be separated from it; hence, the glorious truth must be deduced that all mankind can and must demonstrate it.
All men acknowledge that the nature of health is good; and when there is added to this the fact that it is also divinely mental, the conclusion inevitably follows that thinking good must be health itself. Then, in proportion as men think good thoughts they will express health. How simple! How it lifts thought away from matter to the realm of divine Mind, where all is harmony and holiness! Holiness surely means wholeness; and wholeness must include all that is meant by health. To be healthy, then, one must be holy; and if holy, one would without doubt be healthy.
In "Miscellaneous Writings" (p. 41) Mrs. Eddy says, "Health, alias harmony, is the normal manifestation of man in Science." Now, in the endeavor of the Christian Scientist to demonstrate his unity with the divine Mind, by thinking only the thoughts of "health, alias harmony," he is tempted, again and again, to look to matter for evidence. It is only, however, as he holds his thought steadily to the truth of being that he will find the false evidence of disease yielding to the facts of health. To look away from divine Mind to matter is always to hinder his demonstration.
