1. To be a mirror, to show us our depravity and need for a Savior. While at the same to show us His holiness.
2. The law is the restraint to protect good people from evil by the "dread of punishment", "to be the schoolmaster", and show God's justice to people.
3. To show us what pleases God, and what is offensive. So we know how to worship and respond to Him.
We as Christians are to love, obey, and serve Him, and the law reveals the way (John 14:15). Our freedom is redemption, which means we do not have to fear the curse or God's wrath and punishment from our mistakes. So that through our justification we can obey Him, and His moral law (Duet. 5:1-22; 10:1214; 11:1).
