From 21st Century Science and Health:
We should remember that Life is God, and that God is omnipotent. To forget that God is our Life, is too unconsciously enable suffering instead of contradict it. Not understanding divine Science, the sick usually have little faith in it until they feel its altruistic influence. This shows that faith is not the healer in such cases. The sick admit the reality of affliction, whereas, they should defy it. We should stand up against the testimony of the deceitful senses, while maintaining our spirituality and ongoing likeness to God.
Christ Jesus was an excellent example. Like him, the healer should speak to disease as having authority over it, leaving Soul to prevail over the false evidences of the physical senses and to assert Spirit’s claims over mortality and disease. The same Principle cures both sin and sickness. When divine Science overcomes faith in a fleshly mind; and faith in God destroys all faith in temporal thinking and methods of healing, then sin, disease, and death will disappear.
