They argue that’s why Paul tells them the following verses.
Let not sin therefore reign in your mortal body, to make you obey its passions.
Do not present your members to sin as instruments for unrighteousness, but present yourselves to God as those who have been brought from death to life, and your members to God as instruments for righteousness.
For sin will have no dominion over you, since you are not under law but under grace.
What then? Are we to sin because we are not under law but under grace? By no means.
With due respect this has to do with the fact they people don’t read their Bibles in context.
Let’s read it NOW under context.
Many people think this verse means that if we are under grace, we have licence to sin.
It doesn’t mean that. Paul already said you are no longer under the dominion of sin and sin has no mastery over you.
So the question is what does Paul mean by not subjecting your body to sin?
Paul is contrasting the present state of the believer to his past.
But thanks be to God, that you who were once slaves of sin have become obedient from the heart to the standard of teaching to which you were committed,
and, having been set free from sin, have become slaves of righteousness.
Paul was addressing the issue of law and grace and he was speaking to people about the fact that you are no longer a slave to sin.
It’s now impossible to do that. So he was writing to believers so that they know who they are and thus behave as who they are.
This passage will lead to Romans 7 which he addresses the Jewish audience.
Here Paul is trying to tell them not to return to the Law.
He also says this here.
For while we were living in the flesh, our sinful passions, aroused by the law, were at work in our members to bear fruit for death.
But now we are released from the law, having died to that which held us captive, so that we serve in the new way of the Spirit and not in the old way of the written code.
So you see you are no longer slaves to sin. You are already slaves to righteousness.
When we are slaves to righteousness, we are unable to break free from it.
