Matthew Henry's Commentary
What shall we say then? Shall we continue in sin, that grace may abound?
6:1,2 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.
God forbid. How shall we, that are dead to sin, live any longer therein?
Know ye not, that so many of us as were baptized into Jesus Christ were baptized into his death?
6:3-10 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.
Therefore we are buried with him by baptism into death: that like as Christ was raised up from the dead by the glory of the Father, even so we also should walk in newness of life.
For if we have been planted together in the likeness of his death, we shall be also in the likeness of his resurrection:
Knowing this, that our old man is crucified with him, that the body of sin might be destroyed, that henceforth we should not serve sin.
For he that is dead is freed from sin.
Now if we be dead with Christ, we believe that we shall also live with him:
Knowing that Christ being raised from the dead dieth no more; death hath no more dominion over him.
For in that he died, he died unto sin once: but in that he liveth, he liveth unto God.
Likewise reckon ye also yourselves to be dead indeed unto sin, but alive unto God through Jesus Christ our Lord.
6:11-15 The strongest motives against sin, and to enforce holiness, are here stated. Being made free from the reign of sin, alive unto God, and having the prospect of eternal life, it becomes believers to be greatly concerned to advance thereto. But, as unholy lusts are not quite rooted out in this life, it must be the care of the Christian to resist their motions, earnestly striving, that, through Divine grace, they may not prevail in this mortal state. Let the thought that this state will soon be at an end, encourage the true Christian, as to the motions of lusts, which so often perplex and distress him. Let us present all our powers to God, as weapons or tools ready for the warfare, and work of righteousness, in his service. There is strength in the covenant of grace for us. Sin shall not have dominion. God's promises to us are more powerful and effectual for mortifying sin, than our promises to God. Sin may struggle in a real believer, and create him a great deal of trouble, but it shall not have dominion; it may vex him, but it shall not rule over him. Shall any take occasion from this encouraging doctrine to allow themselves in the practice of any sin? Far be such abominable thoughts, so contrary to the perfections of God, and the design of his gospel, so opposed to being under grace. What can be a stronger motive against sin than the love of Christ? Shall we sin against so much goodness, and such love?
Let not sin therefore reign in your mortal body, that ye should obey it in the lusts thereof.
Neither yield ye your members as instruments of unrighteousness unto sin: but yield yourselves unto God, as those that are alive from the dead, and your members as instruments of righteousness unto God.
For sin shall not have dominion over you: for ye are not under the law, but under grace.
What then? shall we sin, because we are not under the law, but under grace? God forbid.
Know ye not, that to whom ye yield yourselves servants to obey, his servants ye are to whom ye obey; whether of sin unto death, or of obedience unto righteousness?
6:16-20 Every man is the servant of the master to whose commands he yields himself; whether it be the sinful dispositions of his heart, in actions which lead to death, or the new and spiritual obedience implanted by regeneration. The apostle rejoiced now they obeyed from the heart the gospel, into which they were delivered as into a mould. As the same metal becomes a new vessel, when melted and recast in another mould, so the believer has become a new creature. And there is great difference in the liberty of mind and spirit, so opposite to the state of slavery, which the true Christian has in the service of his rightful Lord, whom he is enabled to consider as his Father, and himself as his son and heir, by the adoption of grace. The dominion of sin consists in being willingly slaves thereto, not in being harassed by it as a hated power, struggling for victory. Those who now are the servants of God, once were the slaves of sin.
But God be thanked, that ye were the servants of sin, but ye have obeyed from the heart that form of doctrine which was delivered you.
Being then made free from sin, ye became the servants of righteousness.
I speak after the manner of men because of the infirmity of your flesh: for as ye have yielded your members servants to uncleanness and to iniquity unto iniquity; even so now yield your members servants to righteousness unto holiness.
For when ye were the servants of sin, ye were free from righteousness.
What fruit had ye then in those things whereof ye are now ashamed? for the end of those things is death.
6:21-23 The pleasure and profit of sin do not deserve to be called fruit. Sinners are but ploughing iniquity, sowing vanity, and reaping the same. Shame came into the world with sin, and is still the certain effect of it. The end of sin is death. Though the way may seem pleasant and inviting, yet it will be bitterness in the latter end. From this condemnation the believer is set at liberty, when made free from sin. If the fruit is unto holiness, if there is an active principle of true and growing grace, the end will be everlasting life; a very happy end! Though the way is up-hill, though it is narrow, thorny, and beset, yet everlasting life at the end of it is sure. The gift of God is eternal life. And this gift is through Jesus Christ our Lord. Christ purchased it, prepared it, prepares us for it, preserves us to it; he is the All in all in our salvation.
But now being made free from sin, and become servants to God, ye have your fruit unto holiness, and the end everlasting life.
For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord.
