16 Don't you realize that you become the slave of whatever you choose to obey? You can be a slave to sin, which leads to death, or you can choose to obey God, which leads to righteous living. 17 Thank God! Once you were slaves of sin, but now you wholeheartedly obey this teaching we have given you. 18 Now you are free from your slavery to sin, and you have become slaves to righteous living. 19 Because of the weakness of your human nature, I am using the illustration of slavery to help you understand all this. Previously, you let yourselves be slaves to impurity and lawlessness, which led ever deeper into sin. Now you must give yourselves to be slaves to righteous living so that you will become holy. 20 When you were slaves to sin, you were free from the obligation to do right. 21 And what was the result? You are now ashamed of the things you used to do, things that end in eternal doom. 22 But now you are free from the power of sin and have become slaves of God. Now you do those things that lead to holiness and result in eternal life.

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.
