16 Do you not know that if you yield yourselves to any one as obedient slaves, you are slaves of the one whom you obey, either of sin, which leads to death, or of obedience, which leads to righteousness? 17 But thanks be to God, that you who were once slaves of sin have become obedient from the heart to the standard of teaching to which you were committed, 18 and, having been set free from sin, have become slaves of righteousness. 19 I am speaking in human terms, because of your natural limitations. For just as you once yielded your members to impurity and to greater and greater iniquity, so now yield your members to righteousness for sanctification. 20 When you were slaves of sin, you were free in regard to righteousness. 21 But then what return did you get from the things of which you are now ashamed? The end of those things is death. 22 But now that you have been set free from sin and have become slaves of God, the return you get is sanctification and its end, eternal life.
Matthew Henry's Commentary on Romans 6:16-22
Commentary on Romans 6:16-20
(Read Romans 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.
Commentary on Romans 6:21-23
(Read Romans 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.
