apostle affirms was his, 2 Cor. 4:16, "Though our outward man perish, yet the inward
the flesh are manifest, which are, adultery, fornication, uncleanness, lasciviousness, idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, envyings, murders, drunkenness, revellings, and such like." You know what it did in David and sundry others. Sin aims always at the utmost; every time it rises up to tempt or entice, might it have its own course, it would go out to the utmost sin in that kind. Every unclean thought or glance would be adultery if it could; every covetous desire would be oppression, every thought of unbelief would be atheism, might it grow to its head. Men may come to that, that sin may not be heard speaking a scandalous word in their hearts, -- that is, provoking to any great sin with scandal in its mouth; but yet every rise of lust, might it have its course, would come to the height of villainy: it is like the grave, that is never satisfied. And herein lies no small share of the deceitfulness of sin, by which it prevails to the hardening of men, and so to their ruin, Heb. 3:13, -- it is modest, as it were, in its first motions and proposals, but having once got footing in the heart by them, it constantly makes good its ground, and presseth on to some farther degrees in the same kind. This new acting and pressing forward makes the soul take little notice of what an entrance to a falling off from God is already made; it thinks all is indifferent well if there be no farther progress; and so far as the gospel requireth, -- so far it is hardened: but sin is still pressing forward, and that because it hath no bounds but utter relinquishment of God and opposition to him; that it proceeds towards its height by degrees, making good the ground it hath got by hardness, is not from its nature, but its deceitfulness. Now nothing can prevent this but mortification; that withers the root and strikes at the head of sin every hour, so that whatever it aims at it is crossed in. There is not the best saint in the world but, if he should give over this duty, would fall into as many cursed sins as ever any did of his kind.
4. This is one main reason why the Spirit and the new nature is given unto us, -- that we may have a principle within whereby to oppose sin and lust. "The flesh lusteth against the Spirit." Well! and what then? Why, "The Spirit also lusteth against the flesh," Gal. 5:17. There is a propensity in the Spirit, or spiritual new nature, to be acting against the flesh, as well as in the flesh to be acting against the Spirit: so 2 Pet. 1:4,5. It is our participations of the divine nature that gives us an escape from the pollutions that are in the world through lust; and, Rom. 7:23, there is a law of the mind, as well as a law of the members. Now this is, first, the most unjust and unreasonable thing in the world, when two combatants are engaged, to bind one and keep him up from doing his utmost, and to leave the other at liberty to wound him at his pleasure; and, secondly, the foolishest thing in the world to bind him who fights for our eternal condition, [salvation?] and to let him alone who seeks and violently attempts our everlasting ruin. The contest is for our lives and souls. Not to be daily employing the Spirit and new nature for the mortifying of sin, is to neglect that excellent succour which God hath given us against our greatest enemy. If we neglect to make use of what we have received, God may justly hold his hand from giving us more. His graces, as well as his gifts, are bestowed on us to use, exercise, and trade with. Not to be daily mortifying sin, is to sin against the goodness, kindness, wisdom, grace, and love of God, who hath furnished us with a principle of doing it.
5. Negligence in this duty casts the soul into a perfect contrary condition to that which the apostle affirms was his, 2 Cor. 4:16, "Though our outward man perish, yet the inward
