In the Pearl of Great Price, the Lord speaks of man's purpose on earth: "We will prove them herewith, to see if they will do all things whatsoever the Lord their God shall command them." Obedience is integral to God's plan for us. Jesus Christ gave us the perfect example of this principle, having done the will of His Father completely. We must learn to live the principle of obedience in our own lives so we can return to live with Heavenly Father. When we are obedient to the commandments, we find safety and peace.
