In 1866, a life-threatening injury compelled Mary Baker Eddy to turn wholeheartedly to God. She opened her Bible to an account of Jesus healing a man quickly and completely. A new sense of God, Spirit, as the only reality flooded her thought, and she was healed spontaneously. But she yearned to know how and why.
For the next several years, she continued to search and found in the Bible the underlying laws of God that would form the basis of her teaching and practice of Christian Science.
Mary Baker Eddy’s lifelong spiritual search led to what she later characterized as a discovery.
She saw that God’s laws are powerful spiritual mandates, always present and operating to heal, to redeem, and to bless humanity. To her, it was the practical Christianity that Jesus taught.
Of her developing practice of Christian healing, Mary Baker Eddy wrote that she was called to a patient whom a well-known attending physician had pronounced dying of pneumonia. “On seeing her immediately restored by me without material aid, he asked earnestly if I had a work describing my system of healing. … he urged me immediately to write a book which should explain to the world my curative system of metaphysics” (The First Church of Christ, Scientist, and Miscellany). At that time, she was already writing notes that would develop into her primary work, Science and Health with Key to the Scriptures, which contains the full explanation of Christian Science and its practice of spiritual regeneration and healing.
