6. The believer should remember, that this enemy is not for him to fight against alone, and that his own strength and skill will make but a slender opposition unto it. It will laugh at the shaking of his spear; it can easily insinuate itself, on all occasions, because it lieth so near and close to the soul, always residing there, and is at the believer's right hand whatever he be doing, and is always openly or closely opposing, and that with great facility; for it easily besetteth, Heb. xii. 1, because it lieth within the soul, and in all the faculties of it--in the heart, mind, will, conscience, and affections; so that upon this account, the deceitfulness of the heart is great, and passeth the search of man, Jer. xvii. 9. Man cannot know all the windings and turnings, all the drifts and designs, all the lurking and retiring places, all the falsehoods and double dealings, all the dissimulations, lies, and subterfuges, all the plausible and deceitful pretexts and insinuations of his heart acted and spirited by this law of sin and death. And besides this slight and cunning, it hath strength and power to draw by lusts into destruction and perdition, 1 Tim. iv. 9, and to carry the soul headlong; so that it makes the man's case miserable, Rom. vii. 24. All which would say, that the believer should call in other help than his own, and remember, that "through the Spirit he must mortify the deeds of the body," Rom. viii. 13. 7. And therefore the believer must lay aside all his carnal weapons, in dealing with his adversary, and look out for divine help and assistance, even for the promised Spirit, through which alone he can be instructed and enabled for this great work; for of himself he can do nothing, not so much as think a good thought as of himself, 2 Cor. iii. 5, far less will he be able to oppose such a mighty adversary, that hath so great and many advantages; and therefore all his carnal means, purposes, vows, and fightings in himself, will but render himself weaker, and a readier prey unto this adversary, which gaineth ground while he is so opposed. It is Christ alone and his Spirit, that can destroy the works of the devil, and kill or crucify this enmity.
