The sixth lesson from the Preparatory Series of the Correspondence Course is explored. The topic is “The Great Demonstration.” It is mostly about demonstration, a change of consciousness from error to Truth. Fillmore states, "It is an attainment that must be made through a change of consciousness from the personal to the Christ Consciousness." There is a lot of sharing on sin, the devil, and the adversary. Reincarnation is touched upon as a provision of the Father’s love while not being a part of the law of man’s being.
