The brain nerves which communicate with the entire system are the only medium through which Heaven can communicate to man and affect his inmost life. Whatever disturbs the circulation of the electric currents in the nervous system lessens the strength of the vital powers, and the result is a deadening of the sensibilities of the mind.—Testimonies for the Church 2:347. (Te 13.1) MC VC

Satan is constantly on the alert to bring the race fully under his control. His strongest hold on man is through the appetite, and this he seeks to stimulate in every possible way.—Counsels on Diet and Foods, 150. (Te 13.2) MC VC

Satan’s Scheme to Wreck the Plan of Salvation—Satan had been at war with the government of God, since he first rebelled. His success in tempting Adam and Eve in Eden, and introducing sin into the world, had emboldened this arch foe; and he had proudly boasted to the heavenly angels that when Christ should appear, taking man’s nature, He would be weaker than himself, and that he would overcome Him by his power. (Te 13.3) MC VC

He exulted that Adam and Eve in Eden could not resist his insinuations when he appealed to their appetite. The inhabitants of the old world he overcame in the same manner, through the indulgence of lustful appetite and corrupt passions. Through the gratification of appetite, he had overthrown the Israelites. (Te 13.4) MC VC

He boasted that the Son of God Himself, who was with Moses and Joshua, was not able to resist his power, and lead the favored people of His choice to Canaan; for nearly all who left Egypt died in the wilderness; also, that he had tempted the meek man, Moses, to take to himself glory which God claimed. David and Solomon, who had been especially favored of God, he had induced, through the indulgence of appetite and passion, to incur God’s displeasure. And he boasted that he could yet succeed in thwarting the purpose of God in the salvation of man through Jesus Christ.—Redemption; or the Temptation of Christ, 32. (Te 13.5) MC VC
