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.

20. For when ye were the servants—"were servants"

of Sin, ye were free from—rather, "in respect of"

Righteousness—Difficulties have been made about this clause where none exist. The import of it seems clearly to be this:—"Since no servant can serve two masters, much less where their interests come into deadly collision, and each demands the whole man, so, while ye were in the service of Sin ye were in no proper sense the servants of Righteousness, and never did it one act of real service: whatever might be your conviction of the claims of Righteousness, your real services were all and always given to Sin: Thus had ye full proof of the nature and advantages of Sin's service." The searching question with which this is followed up, shows that this is the meaning.
