Cheap Law

In Matthew 5, Jesus shows unambiguously that the greatest obstacle to getting the gospel is not “cheap grace” but “cheap law”–the idea that God accepts anything less than the perfect righteousness of Jesus. (By the way, the proper response to the charge of “cheap grace” is not to make grace expensive by adding a thousand qualifications and footnotes, but rather to declare that grace is free!)

 Cheap law weakens God’s demand for perfection, and in doing so, breaths life into the old creature and his quest for a righteousness of his own making.
Cheap law will never quiet the self-righteous being because it invites him to keep haggling over what he can do apart from Jesus. And that is why law must be costly. It must always get to the heart of the matter. It’s not only murder that deserves death, but hate. It’s not only adultery that condemns, but lust. Not only theft, but coveting. It’s not only what is done with your hands that is judged, but what is done in your heart. And so – it should be clear – this is not “let’s make a deal.” The deals have been cut. The law of Moses is more than you can afford. The Son that God did not spare is priceless. The grace Jesus gives is free. That’s all there is. But cheap law keeps us searching for something to leverage against our poverty.
