I enjoyed this insight from Jonty Rhodes in Covenants Made Simple. He is commenting on John 8:44, “You are of your father the devil, and your will is to do your father’s desires. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he lies, he speaks out of his own character, for he is a liar and the father of lies. ”
Satan is the arch assassin. His mission, his driving appetite, is for death. Remember, death in the Bible isn’t just about physical death, but eternal separation from God in hell. This is Satan’s fate, and he is intent on bringing as many humans as possible with him: he is the ultimate serial killer. But notice how he kills. Rather than marauding around the world with flaming pitchfork as the cartoons would have us believe, Satan kills with his tongue. Jesus tells us not that Satan murders and lies, but that he murders by lies: “not holding to the truth.” He kills Eve not by stabbing her, but by speaking to her; not with a sword, but with a sermon.
