Romans 6:12-23
Paul concludes Chapter 6 with several contrasts around the topic of Sin. His use of slavery and enslavement as illustrations may be off-putting to some, and yet, clearly illustrate the power and choices related to sin before and after salvation.
There wasn’t enough time to include everything considered from the text, so I’ll include them here for your consideration.
Spurgeon on Romans 6:14 While we were under the law and simply heard it command us to do our duty, the command seemed to awaken all the hostility of our nature so that we remained under the dominion of sin. But now no longer does the law speak to us as it did before. We are not now under the law, but another principle governs us. The grace, the favor, the love God has shown us in Christ Jesus appeals to our hearts, and we cheerfully yield to it the obedience our unregenerate spirits refused to render when the law demanded it.
Spurgeon on Romans 6:16 The one who lives a life of sin proves he is the servant of sin, for he has obeyed its commands. Let that person know assuredly that he has nothing to do with Christ while living in sin. But the one who lives in obedience to Christ and seeks after righteousness and true holiness is evidently the servant of righteousness and so the servant of God.
