Shall we continue in sin that grace may abound? He puts and rejects the same objection as before. (Chap. iii. ver. 7.) And having set forth in the last chapter the grace and advantages by Christ’s coming, he now exhorts them to avoid sinning, and live in the grace of God. (Witham)
The apostle's transition, which joins this discourse with the former, is observable: "What shall we say then? v. 1. What use shall we make of this sweet and comfortable doctrine? Shall we do evil that good may come, as some say we do? ch. 3 8. Shall we continue in sin that grace may abound? Shall we hence take encouragement to sin with so much the more boldness, because the more sin we commit the more will the grace of God be magnified in our pardon? Is this a use to be made of it?" No, it is an abuse, and the apostle startles at the thought of it (v. 2): "God forbid; far be it from us to think such a thought." He entertains the objection as Christ did the devil's blackest temptation (Matt 4 10): Get thee hence, Satan. Those opinions that give any countenance to sin, or open a door to practical immoralities, how specious and plausible soever they be rendered, by the pretension of advancing free grace, are to be rejected with the greatest abhorrence; for the truth as it is in Jesus is a truth according to godliness, Tit 1 1. The apostle is very full in pressing the necessity of holiness in this chapter, which may be reduced to two heads:—His exhortations to holiness, which show the nature of it; and his motives or arguments to enforce those exhortations, which show the necessity of it.
Verses 1-2 The apostle is very full in pressing the necessity of holiness. He does not explain away the free grace of the gospel, but he shows that connexion between justification and holiness are inseparable. Let the thought be abhorred, of continuing in sin that grace may abound. True believers are dead to sin, therefore they ought not to follow it. No man can at the same time be both dead and alive. He is a fool who, desiring to be dead unto sin, thinks he may live in it.
In that corruption: for though the guiltiness of sin be not imputed to us, yet the corruption remaineth still in us: the which Sanctification that followeth Justification killeth by little and little. He passeth now to another benefit of Christ, which is called sanctification or regeneration.
1. Mortification, putting off the old man; several ways this is expressed. (1.) We must live no longer in sin (v. 2), we must not be as we have been nor do as we have done. The time past of our life must suffice, 1 Peter 4 3. Though there are none that live without sin, yet, blessed be God, there are those that do not live in sin, do not live in it as their element, do not make a trade of it: this is to be sanctified. (2.) The body of sin must be destroyed, v. 6. The corruption that dwelleth in us is the body of sin, consisting of many parts and members, as a body. This is the root to which the axe must be laid. We must not only cease from the acts of sin (this may be done through the influence of outward restraints, or other inducements), but we must get the vicious habits and inclinations weakened and destroyed; not only cast away the idols of iniquity out of the heart.—That henceforth we should not serve sin. The actual transgression is certainly in a great measure prevented by the crucifying and killing of the original corruption. Destroy the body of sin, and then, though there should be Canaanites remaining in the land, yet the Israelites will not be slaves to them. It is the body of sin that sways the sceptre, wields the iron rod; destroy this, and the yoke is broken. The destruction of Eglon the tyrant is the deliverance of oppressed Israel from the Moabites. (3.) We must be dead indeed unto sin, v. 11. As the death of the oppressor is a release, so much more is the death of the oppressed, Job 3 17, 18. Death brings a writ of ease to the weary. Thus must we be dead to sin, obey it, observe it, regard it, fulfil its will no more than he that is dead doth his quandam task-masters—be as indifference to the pleasures and delights of sin as a man that is dying is to his former diversions. He that is dead is separated from his former company, converse, business, enjoyments, employments, is not what he was, does not what he did, has not what he had. Death makes a mighty change; such a change doth sanctification make in the soul, it cuts off all correspondence with sin. (4.) Sin must not reign in our mortal bodies that we should obey it, v. 12. Though sin may remain as an outlaw, though it may oppress as a tyrant, yet let it not reign as a king. Let it not make laws, nor preside in councils, nor command the militia; let it not be uppermost in the soul, so that we should obey it. Though we may be sometimes overtaken and overcome by it, yet let us never be obedient to it in the lusts thereof; let not sinful lusts be a law to you, to which you would yield a consenting obedience. In the lusts thereof—en tais epithymiais autou. It refers to the body, not to sin. Sin lies very much in the gratifying of the body, and humouring that. And there is a reason implied in the phrase your mortal body; because it is a mortal body, and hastening apace to the dust, therefore let not sin reign in it. It was sin that made our bodies mortal, and therefore do not yield obedience to such an enemy. (5.) We must not yield our members as instruments of unrighteousness, v. 13. The members of the body are made use of by the corrupt nature as tools, by which the wills of the flesh are fulfilled; but we must not consent to that abuse. The members of the body are fearfully and wonderfully made; it is a pity they should be the devil's tools of unrighteousness unto sin, instruments of the sinful actions, according to the sinful dispositions. Unrighteousness is unto sin; the sinful acts confirm and strengthen the sinful habits; one sin begets another; it is like the letting forth of water, therefore leave it before it be meddled with. The members of the body may perhaps, through the prevalency of temptation, be forced to be instruments of sin; but do not yield them to be so, do not consent to it. This is one branch of sanctification, the mortification of sin.
Dead to sin, &c. We are then dead to sin when we neither live in sin by serving it, nor sin lives in us by reigning; in this case, how can we still live in it by yielding to its desires? St. Augustine (chap. vi. de spiritu et litera) thus explains the passage: when grace has caused us to die to sin; if we live again in it, we must be exceedingly ungrateful to grace. (Estius)
Verses 3-10 Baptism teaches the necessity of dying to sin, and being as it were buried from all ungodly and unholy pursuits, and of rising to walk with God in newness of life. Unholy professors may have had the outward sign of a death unto sin, and a new birth unto righteousness, but they never passed from the family of Satan to that of God. The corrupt nature, called the old man, because derived from our first father Adam, is crucified with Christ, in every true believer, by the grace derived from the cross. It is weakened and in a dying state, though it yet struggles for life, and even for victory. But the whole body of sin, whatever is not according to the holy law of God, must be done away, so that the believer may no more be the slave of sin, but live to God, and find happiness in his service.
&c. We…are baptized in his death. Greek, unto his death. The apostle here alludes to the manner of administering the sacrament of baptism, which was then done by immersion or by plunging the person baptized under the water, in which he finds a resemblance of Christ’s death and burial under ground, and of his resurrection to an immortal life. So must we after baptism rise to lead a quite different life: having been also, when we were baptized and made Christians, planted as branches ingrafted in Christ, let us endeavour to bring forth the fruits of a virtuous life. (Witham) — Old man…body of sin. Our corrupt state, subject to sin and concupiscence, coming to us from Adam, is called our old man, as our state, reformed in and by Christ, is called the new man. And the vices and sins which then ruled in us, are named the body of sin. (Challoner) — The old and sinful man we must look upon as crucified with him, and the body of sin, or our sinful body, destroyed. We must look upon ourselves as dead to sin, and that we must sin no more, as Christ being once risen, dies no more. (Witham)
