Since the announcement to the serpent in Eden, “I will put enmity between thee and the woman, and between thy seed and her seed” (Genesis 3:15), Satan had known that he did not hold absolute sway over the world. There was seen in men the working of a power that withstood his dominion. With intense interest he watched the sacrifices offered by Adam and his sons. In these ceremonies he discerned a symbol of communion between earth and heaven. He set himself to intercept this communion. He misrepresented God, and misinterpreted the rites that pointed to the Saviour. Men were led to fear God as one who delighted in their destruction. The sacrifices that should have revealed His love were offered only to appease His wrath. Satan excited the evil passions of men, in order to fasten his rule upon them. When God’s written word was given, Satan studied the prophecies of the Saviour’s advent. From generation to generation he worked to blind the people to these prophecies, that they might reject Christ at His coming.
