The soldiers of Christ have a fleshly appetite, and the remnants of ignorance and error in their minds, and of earthliness, and carnality, and averseness to God in their wills, with a nearness to this world, and much strangeness to the world to come. And here is too much advantage for Satan to work on by his temptations. 10. But it is the predominant part within us, and the scope of our lives, which showeth which of the armies we belong to. And thus we must give up our names and hearts to Christ, and engage under his conduct against the devil, and conquer to the death, if we will be saved. Not to fight against the bare name of the devil; for so will his own soldiers, and spit at his name, and hang a witch that makes a contract with him: but it is to fight against his cause and work, which is by fighting against the world and the flesh, and for the glory of God. [Sidenote: The method.] In opening to you this holy war, I shall, First, Shew you what we must do on the offensive part. Secondly, What on the defensive part. And here I shall show you, I. What it is that the tempter aimeth at as his end. II. What matter or ground he worketh upon. III. What are his succours and assistance. IV. What kind of officers and instruments he useth. V. What are his methods and actual temptations, 1. To actual sin, 2. Against our duty to God. First, Our offensive arms are to be used, 1. Against the power of sin within us; and all its advantages and helps: for while Satan ruleth and possesseth us within, we shall never well oppose him without. 2. Against sin in others, as far as we have opportunity. 3. Against the credit and honour of sin in the world: as the devil's servants would bring light and holiness into disgrace, so Christ's servants must cast disgrace and shame upon sin and darkness. 4. Against all the reasonings of sinners, and their subtle fallacies, whereby they would deceive. 5. Against the passions and violent lusts which are the causes of men's other sins. 6. Against the holds and helps of sin, as false teachers, profane revilers, ignorance, and deceit. Only take heed that on this pretence we step not out of our ranks and places, to pull down the powers of the world by rebellions: "For the weapons of our warfare are not carnal," 2 Cor. x. 4.
