From 21st Century Science and Health:

If God causes a person to be sick, sickness must be good and therefore health must be evil, for all that He makes is good and will stand forever. Or, if violation of Gods law produces sickness, it is right to be sick; and we cannot if we would, and should not if we could, annul the decrees of wisdom. It is the transgression of a belief of human mind, not of a physical law or law of divine Mind, which causes the belief of sickness. The remedy is Truth, not mortality with its beginnings and endingsthe truth that disease is illusion. Anything unlike God is unreal.

If sickness is real, it belongs to spirituality; if sickness is true, it is a part of Truth. Would you attempt with drugs, or without, to destroy a quality or condition of Truth? Lets say sickness is not real. Lets say sickness and sin are unfiltered and unprocessed images that can be filtered and processed by divine Science to show us health, holiness, and spirituality. This process or clarification of information is accomplished through Spirit, Christ, or the advanced appearing of Truth. This is the deliverance which comes through God, the divine Principle, Love, as demonstrated by Jesus.
