Illness is well known to produce fear among humanity—so much so that people rarely question this relationship. Less well known but far more important to understand is the reverse—that fear breeds illness.
In many places the Bible assures us we need not fear, and Mary Baker Eddy, in Science and Health with Key to the Scriptures—which explains both the mental cause of disease and its cure through prayer—states, “Fear is the fountain of sickness, and you master fear and sin through divine Mind; hence it is through divine Mind that you overcome disease” (pp. 391–392).
What is divine Mind? Mind is a synonym for God, the one source and substance of all real being, intelligence, and wisdom. This divine consciousness, which is infinite and wholly good, does not include disease.
