Less than a century ago Mrs. Eddy made a spiritual discovery that is proving to be of inestimable value to the world. In this discovery she came face to face with a power that she had but dimly discerned theretofore. This power freed her from the effects of a severe accident. It was the same power, the Christ-power, that had enabled Jesus to heal "all manner of sickness and all manner of disease among the people" (Matt. 4:23).
Others might have considered such a healing as Mrs. Eddy's to be a miracle and let it go at that. But not Mrs. Eddy. She was convinced that she had discovered the operation of a spiritual law, with which the Master had been thoroughly familiar— a law that, as it was understood, would bring to humanity freedom from sin and disease. As our Leader puts it in "Retrospection and Introspection" (p. 24), "My immediate recovery from the effects of an injury caused by an accident, an injury that neither medicine nor surgery could reach, was the falling apple that led me to the discovery how to be well myself, and how to make others so."
Mrs. Eddy continued her investigations much as a physical scientist would pursue investigations in his particular field. One unfoldment led to another as Truth revealed itself to her. The Bible was her textbook. She writes in Science and Health (p. 110), "The Scriptures were illumined; reason and revelation were reconciled, and afterwards the truth of Christian Science was demonstrated."
