18 one whose commands set you free to live openly in his freedom! 19 I'm using this freedom language because it's easy to picture. You can readily recall, can't you, how at one time the more you did just what you felt like doing - not caring about others, not caring about God - the worse your life became and the less freedom you had? And how much different is it now as you live in God's freedom, your lives healed and expansive in holiness? 20 As long as you did what you felt like doing, ignoring God, you didn't have to bother with right thinking or right living, or right anything for that matter.
Matthew Henry's Commentary on Romans 6:18-20
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.
