Desire becomes sin when it fails to include love of God or men. Further, I think there are two practical tests as to when we are coveting against God or men; first, I am to love God enough to be contented; second, I am to love men enough not to envy.

When I lack proper contentment, either I have forgotten that God is God, or I have ceased to be submissive to him. We are now speaking about a practical test to judge if we are coveting against God. A quiet disposition and a heart giving thanks at any given moment is the real test of the extent to which we love God at that moment.
