Sometimes by deceiving us, sometimes by suggesting unbelief or unfaithfulness to God, sometimes by one kind of tactic and sometimes by another, he is always carrying on a campaign against our souls. Satan has desired to have you that he may sift you as wheat (Luke 22:31). This mighty adversary must be resisted daily if we want to be saved. But this lineage of demons does not go out (Matthew 17:21) except by watching, praying, fighting, and putting on the whole armor of God (Ephesians 6:11). The strong man armed will never be kept out of our hearts without a daily battle.
