You ignore the simple fact that we all sin. Do you know the law and try to keep it? It is scattered through the Torah! Here it is. Disobeying any of these laws is sin.This is definitely one of those passages where we can let it go as a 'agree to disagree' passage.
So without going into that matter, lol, I will say there is a distinct difference between struggling with sin, and living in it. Too many 'Christians' use this passage to rationalize living defeated in the flesh without a struggle and thinking they are saved despite that. This is a particularly common thing at this time in church history. It's based in a horrible distortion of Paul's teaching of how justification is not by works, but rather by faith apart from works. Many in the church thinks that means, "oh, I don't have to have works! Bartender, make it a double!"
In addition to the 10 commandments there are the laws scattered through the Torah.
