God's healing power runs all through nature. If a human being cuts his flesh or breaks a bone, nature at once begins to heal the injury, and thus preserve the man's life. But man can place himself in a position where nature is trammeled so that she cannot do her work.... If tobacco is used, ... the healing power of nature is weakened to a greater or less extent.... When intoxicating liquor is used, the system is not able to resist disease in its original God-given power as a healer. It is God who has made the provision that nature shall work to restore the exhausted powers. The power is of God. He is the Great Healer.—Letter 77, 1899. MM 11.6
