In a passage cherished by Christian Scientists, and worthy of the most careful consideration of everyone, Mary Baker Eddy writes (The First Church of Christ, Scientist, and Miscellany, p. 210), "Beloved Christian Scientists, keep your minds so filled with Truth and Love, that sin, disease, and death cannot enter them." And she adds: "Good thoughts are an impervious armor; clad therewith you are completely shielded from the attacks of error of every sort. And not only yourselves are safe, but all whom your thoughts rest upon are thereby benefited."
These words have inspired a multitude of men and women to prove that they were not in fact subject to danger, as they had seemed to be. Instead of having to yield to "the attacks of error," or evil, in its various forms—injury, disease, loss, and the like—they have found that through their own thinking, based on the understanding of the presence and power of God, they could defend themselves and remain unharmed. And their experience stands as a heartening challenge to people everywhere not to submit to "the terror by night," "the arrow that flieth by day," "the pestilence that walketh in darkness," or "the destruction that wasteth at noonday," of which the Psalmist wrote, but to prove in accordance with his inspired assurances their dominion over evil.
How are these proofs to be accomplished? What are the facts which make them possible? What, exactly, are the good thoughts which constitute "an impervious armor," and how is one to adopt them effectually?
