A. As a guide for happy, abundant living. God created us for happiness, peace, long life, and all the blessings for which our hearts long. His law is a road map that points out the right paths to true happiness, for by the law is the knowledge of sin (Romans 3:20; Romans 7:7).
B. To show us the difference between right and wrong. God’s law is like a mirror — it points out wrongdoing in our lives much like a mirror points out dirt on our faces.
C. To protect us from danger and tragedy. God’s law is like a strong fence that protects us from falsehood, murder, idolatry, theft, and many other evils that destroy life and peace.
D. To help us know God (1 John 2:3).
