This sermon by Charles Spurgeon explains that God's law was never meant to save people, but it has important purposes in leading them to Jesus. The law's main job is to show people how sinful they are and how impossible it is to be good enough on their own, like a mirror that reveals dirt on your face so you know you need to wash it. Once people realize they can never keep God's law perfectly, they understand they need Jesus Christ's perfect righteousness to save them, because only his sacrifice and obedience can make them right with God.

A sermon delivered by Charles Spurgeon on April 19, 1857.
