Why did God give us the Ten Commandments?

"He that keepeth the law, happy is he." Proverbs 29:18. "Keep my commandments: For length of days, and long life, and peace, shall they add to thee." Proverbs 3:1, 2. Answer: A. As a guide for happy, abundant living. God created us to enjoy happiness, peace, long life, contentment, accomplishment, and all the other great blessings for which our hearts long. God's law is the road map that points out the right paths to follow in order to find this true, supreme happiness.
