16 Are you not conscious that you are the servants of him to whom you give yourselves to do his desire? if to sin, the end being death, or if to do the desire of God, the end being righteousness. 17 But praise be to God that though you were the servants of sin, you have now given yourselves freely to that form of teaching under which you were placed; 18 And being made free from sin you have been made the servants of righteousness. 19 I am using words in the way of men, because your flesh is feeble: as you gave your bodies as servants to what is unclean, and to evil to do evil, so now give them as servants to righteousness to do what is holy. 20 When you were servants of sin you were free from righteousness. 21 What fruit had you at that time in the things which are now a shame to you? for the end of such things is death. 22 But now, being free from sin, and having been made servants to God, you have your fruit in that which is holy, and the end is 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.
