Through spiritualism, Satan appears as a benefactor of the race, healing the diseases of the people, and professing to present a new and more exalted system of religious faith; but at the same time he works as a destroyer. His temptations are leading multitudes to ruin. Intemperance dethrones reason; sensual indulgence, strife, and bloodshed follow. Satan delights in war, for it excites the worst passions of the soul and then sweeps into eternity its victims steeped in vice and blood. It is his object to incite the nations to war against one another, for he can thus divert the minds of the people from the work of preparation to stand in the day of God. DD 33.2
Satan works through the elements also to garner his harvest of unprepared souls. He has studied the secrets of the laboratories of nature, and he uses all his power to control the elements as far as God allows. When he was suffered to afflict Job, how quickly flocks and herds, servants, houses, children, were swept away, one trouble succeeding another as in a moment. It is God that shields His creatures and hedges them in from the power of the destroyer. But the Christian world have shown contempt for the law of Jehovah; and the Lord will do just what He has declared that He would—He will withdraw His blessings from the earth and remove His protecting care from those who are rebelling against His law and teaching and forcing others to do the same. Satan has control of all whom God does not especially guard. He will favor and prosper some in order to further his own designs, and he will bring trouble upon others and lead men to believe that it is God who is afflicting them. DD 33.3
While appearing to the children of men as a great physician who can heal all their maladies, he will bring disease and disaster, until populous cities are reduced to ruin and desolation. Even now he is at work. In accidents and calamities by sea and by land, in great conflagrations, in fierce tornadoes and terrific hailstorms, in tempests, floods, cyclones, tidal waves, and earthquakes, in every place and in a thousand forms, Satan is exercising his power. He sweeps away the ripening harvest, and famine and distress follow. He imparts to the air a deadly taint, and thousands perish by the pestilence. These visitations are to become more and more frequent and disastrous. Destruction will be upon both man and beast. “The earth mourneth and fadeth away,” “the haughty people ... do languish. The earth also is defiled under the inhabitants thereof; because they have transgressed the laws, changed the ordinance, broken the everlasting covenant.” Isaiah 24:4, 5. DD 33.4
