NO, IT IS NOT THE PURPOSE OF THE LAW
The purpose of the law is exactly what Paul said it was. to prove, if we have coveted, we have failed to live up to Gods righteous standard. and need Christ. It is a schoolmaster TO LEAD IS TO CHRIST. But after we have faith, WE NO LONGER NEED THE SCHOOLMASTER.
The law. "do not covet" does not tell us how to do that. it can;t it just plainly says, Do not covet.
all it can do is give us a false sense of security, I do not covet my neighbor so I must love him, yet in reality I can hate the person with everything I have. or he has nothing I want to begin with.
Just because I do not covet what he has, does not mean I love him.
Thats the problem with your style of legalism, it gives people a false hope. a false sense of security, and a false sense of what love really is.
