Only when we see that the way of God's law is absolutely inflexible will we see that God's grace is absolutely indispensable. A high view of the law reminds us that God accepts us on the basis of Christ's perfection, not our progress. Grace, properly understood, is the movement of a holy God toward an unholy people. He doesn't cheapen the law or ease its requirements. He fulfills them in his Son, who then gives his righteousness to us. That's the gospel. Pure and simple.
