Satan Uses Influences of Mind on Mind

"Cast out of heaven, Satan set up his kingdom in this world, and ever since he has been untiringly striving to seduce human beings from their allegiance to God. He uses the same power that he used in heaven— the influence of mind on mind. Men become tempters of their fellowmen. The strong, corrupting sentiments of Satan are cherished, and they exert a masterly, compelling power. Under the influence of these sentiments, men bind up with one another in confederacies...and in secret societies. There are at work in the world agencies that God will not much longer tolerate."

Satan's Studied Purpose to Employ Powers for Selfish Ends

"Satan has nets and snares, like the snares of the fowler, all prepared to entrap souls. It is his studied purpose that men shall employ their God-given powers for selfish ends rather than yield them to glorify God. God would have men engage in a work that will bring them peace and joy and will render them eternal profit; but Satan wants us to concentrate our efforts for that which profiteth not, for the things that perish with the using."
