This is the doctrine of Christian Science: that divine Love cannot be deprived of its manifestation, or object; that joy cannot be turned into sorrow, for sorrow is not the master of joy; that good can never produce evil; that matter can never produce mind nor life result in death. The perfect man - governed by God, his perfect Principle - is sinless and eternal.
Mary Baker EddyHappiness is spiritual, born of truth and love. It is unselfish; therefore it cannot exist alone, but requires all mankind to share it.
Mary Baker EddyHold thought steadfastly to the enduring, the good, and the true, and you will bring these into your experience proportionately to their occupancy of your thoughts.
Mary Baker EddyWe know that a statement proved to be good must be oorrect. New thoughts are constantly obtaining the floor. These two theories - that all is matter, or that all is Mind-will dispute the ground, until one is acknowledged to be the victor. Discussing his campaign, General Grant said: "I propose to fight it out on this line, if it takes all summer." Science says: All is Mind and Mind's idea. You must fight it out on this line. Matter can afford you no aid.
