4. Diet Modified Disposition, Activated Mind—The state of the mind has largely to do with the health of the body, and especially with the health of the digestive organs. As a general thing, the Lord did not provide His people with flesh meat in the desert, because He knew that the use of this diet would create disease and insubordination. In order to modify the disposition, and bring the higher powers of the mind into active exercise, He removed from them the flesh of dead animals. He gave them angel′s food, manna from heaven (Manuscript 38, 1898).
