Purpose of the Law
On a warm, summer night, my wife and I were traveling in our car with Micah, our 3-year-old son, who sat in the back seat. After many miles of driving in the darkness, we came to a stop in a remote area. The brightness of the traffic light revealed all of the dirt, dead bugs, and insects on our windshield. Micah said, "Look, how dirty!"
My wife and I didn't think much of his comment until a moment later when we drove on—away from the light and back into the darkness. Upon reentering the darkness, we could no longer see the mess on our windshield, and Micah quickly piped up and said, "Now the glass is clean!"
Before the law came, the dirt within us hid under the darkness. But when God gave the law, its light shined on the windshield of our hearts and revealed the filth of sin we'd collected on our journey. The law, then, is a light that shows us how sinful we really are. It cannot cleanse us or make us whole. But it does starkly highlight the true situation of our souls—and thus can lead us to Christ.
