This verse is not talking about the law of commandments.
If you consider yourself obligated before the law to keep its commandments, then you yourself will be responsible, because you have rejected grace and redemption in Christ.
So which circles back to the synopsis of your argument, Christians are not bound to any standard, so, therefore, they can do whatever they want and define the standard for themselves and claim the Holy Spirit behind it and trust that I know what's good & evil, & I know how the Spirit's voice is, so I don't need the Bible, God's Word, or His perfect will & law to measure up against it (which according to your ideology, it's sinful, which is another contradictory and means since God owns something sinful, we shouldn't trust Him because He lied about being sinless, therefore the whole Bible is tainted and cannot be trusted).
Since the law says do not murder, do not steal, do not commit adultery, honor your parents, do not envy, do not have any other Gods before Him, and taking light breeze's argument that the law is sinful and we are free from it.
That means the command to not murder is evil, therefore I can still.
The command to obey my parents is evil, therefore I can disrespect them all I want.
That means that the command against envying, murdering, lying, and idolatry is evil, since the law is evil, and that is apart of the law, I can therefore not commit evil by not obeying the law, and I can steal, murder, lie, and worship whatever or whoever I want before God.
You can deny it, but that is what you're argument is saying...
And also to note, the same claims your getting your ideology from, comes from the same Word, Written Will of God you're trying to say is sinful. How can you use something from itself to prove itself is a fraud, unless it's contradictory.
If you truly believe this isn't the case, then only 2 things are possible. You're interpretation of Scripture is wrong, or my interpretation of what your interpretation of Scripture is wrong (which before you rush to pick option 2, explain how it's wrong and how that reconciles with Romans? You don't use Scripture to refute Scripture, all of it is God-breathed and coaligns with each other - 2 Timothy 3:16-17)
That is, your mind is actually rebelling
Opinion without any evidence behind it, doesn't even make any sense.
