2. It is supposed that he is the deadly enemy of Christ and us.[105] He was once an angel, and fell from his first estate by sin, and a world of evil spirits with him; and it is probable his envy against mankind might be the greater, as knowing that we were made to succeed him and his followers, in their state of glory: for Christ saith, that we shall "be equal with the angels," Luke xx. 36. He showed his enmity to man in our innocency, and by his temptation caused our fall and misery. But after the fall, God put an enmity into the nature of man against devils, as a merciful preservative against temptation: so that as the whole nature of man abhorreth the nature of serpents, so doth the soul abhor and dread the diabolical nature. And, therefore, so far as the devil is seen in a temptation now, so far it is frustrated; till the enmity in nature be overcome by his deceits: and this help nature hath against temptation, which it seems our nature had not before the fall, as not knowing the malice of the devil against us. There is a natural enmity to the devil himself put into all the woman's natural seed: but the moral enmity against his sinful temptations and works, is put only into the spiritual seed by the Holy Ghost (except what remnants are in the light of nature). I will be brief of all this and the next, having spoken of them more largely in my "Treatise against Infidelity," Part iii. The devil's names do tell us what he is.[106] In the Old Testament he is called, 1. The "serpent," Gen. iii. 2. The Hebrew word, translated "devils," in Lev. xvii. 7, and Isa. xiii. 21, signifieth hairy, as satyrs are described; and sometimes he-goats; because in such shapes he oft appeareth. 3. He is called "Satan," Zech. iii. 1. 4. "An evil spirit," 1 Sam. xviii. 10. 5. "A lying spirit," 1 Kings xxii. 22; for he "is a liar, and the father of it," John viii. 44. 6. His offspring is called "a spirit of uncleanness," Zech. xiii. 2. 7. And he (or his spawn) is called "a spirit of fornication," Hos. iv. 12; that is, idolatry. 8. "A perverse spirit, causing staggering and giddiness as a drunken man," Isa. xix. 14.
