In the New Testament, 1. He is sometimes called simply "a spirit," Mark ix. 20, 26; Luke ix. 39; x. 20. 2. Sometimes, πνευματα ακαθαρτα, "unclean spirits," Luke vi. 18; as contrary to the Holy Spirit; and that from their nature and effects. 3. And after, δαιμομιον, "demons," a word taken in a good sense in heathen writers, but not in Scripture; because they worshipped devils under that name, (unless perhaps Acts xvii. 18; 1 Tim. iv. 1.) And, δαιμων with respect to their knowledge, and, as some think, to the knowledge promised to Adam, in the temptation. 4. Πειραζων, "the tempter," Matt. iv. 5. "Satan," Matt. iv.; 1 Pet. v. 8. 6. Εχθρος, "an enemy," Matt. xiii. 28, 39. 7. "The strong man armed," Matt. xii. 8. "Angels," 1 Cor. vi. 3; 2 Pet. ii. 4. "Angels which kept not their first state," Jude 6. 9. "A spirit of divination," Acts xvi. 16. 10. "A roaring lion," 1 Pet. v. 8. 11. "A murderer," John viii. 44. 12. "Belial," 2 Cor. vi. 15. 13. "Beelzebub," Matt. xii. the "god of flies." 14. "The prince of this world," John xii. 21, from his power over wicked men. 15. "The god of this world," 2 Cor. iv. 5, because the world obey him. 16. "The prince of the power of the air," Eph. ii. 2. 17. "The ruler of the darkness of this world," Eph. vi. 12. "Principalities and powers." 18. "The father of the wicked," John viii. 44. 19. "The dragon, and the old serpent," Rev. xii. 20. Διαβολος, "the calumniator," or "false accuser," often. 21. Ὁ πονηρος "the evil one," Matt. xxiii. 19. 22. "An evil spirit," Acts xix. 15. 23. Απολλυων, "the destroyer," and "Abaddon," the "king of the locusts," and "angel of the bottomless pit," Rev. ix. 11, (unless that speak of antichrist). 3. He is too strong an enemy for lapsed sinful man to deal with of himself. If he conquered us in innocency, what may he do now? He is dangerous, (1.) By the greatness of his subtlety. (2.) By the greatness of his power. (3.) By the greatness of his malice. And hence, (4.) By his constant diligence, watching when we sleep, Matt. xiii. 25; and "seeking night and day to devour," 1 Pet. v. 8; Rev. xii. 4. 4. Therefore Christ hath engaged himself in our cause, and is become the "Captain of our salvation," Heb. ii. 10.[107] And the world is formed into two armies, that live in continual war: the devil is the prince and general of one, and his angels and wicked men are his armies: Christ is the King and General of the other, and his angels (Heb. ii. 14) and saints are his army. Between these two armies are the greatest conflict in the world. 5. It is supposed also, that this war is carried on, on both sides, within us, and without us; by inward solicitations, and outward means, which are fitted thereunto.
