Paul isn't just talking about avoiding outward actions. What deeper truth is he hinting at regarding God's law?
The Jewish leaders prided themselves on knowing and teaching the Law. However, Paul exposes their failure not just in outward actions, but in their understanding and application of the Law.
Empty Boasting
Their 'boasting in the law' was hollow because they broke it. They focused on external rules, perhaps even thinking adherence to certain rituals or pronouncements was enough. But Paul shows that true adherence involves the heart and consistent practice. Knowing the law intellectually is one thing; being transformed by it is another.
Sin Against God
While the text mentions sins against neighbors (stealing, adultery), it also strongly implies sins against God, such as sacrilege and not giving God the glory due Him. This points to a core issue: a failure to honor God Himself, despite their privileged position as teachers of His law.
