Occasionally I’ve heard someone say that there has been so much progress in the medical field since Mary Baker Eddy’s time that there is no need for Christian Science today. 

Christian Scientists certainly have no quarrel with anyone who chooses medical treatment and who is no doubt grateful for whatever these medical means do to alleviate or manage illness. But the beauty of Christian Science is that it depends wholly on God, who never changes, and “who healeth all thy diseases” (Psalms 103:3). As I and many others have experienced, we can expect not just relief from pain or management of symptoms but complete and permanent healing.

Christ Jesus proved the healing power of God in the thousands of healings he performed, and he promised that those who believed in him would do the works that he did and that this healing work would grow and expand. And when Mrs. Eddy discovered the divine laws that undergirded Jesus’ healing works—what she termed “the Science of Christian healing” (Science and Health with Key to the Scriptures, p. 144)—she demonstrated their continued dependability by healing, through prayer alone, diverse cases of physical and mental disorder, many of which had been deemed hopeless by medical doctors.
