I have commanded you today to love the Lord your God and to follow His paths and to keep His laws, so that you will live and become a great nation, and so that the Lord your God will bless you and the land you are about to possess. The Ten Commandments were given so that all could see the extent of their failure to obey God's laws. But the more we see our sinfulness, the more we see God's abounding grace forgiving us. Obedience can keep us from disease. If you will listen to the voice of the Lord your God, and obey it, and do what is right, then I will not make you suffer the diseases I sent on the Egyptians, for I am the Lord who heals you.
Obedience is the key to a successful life.
Constantly remind the people about these laws, and you yourself must think about them every day and every night so that you will be sure to obey all of them. For only then will you succeed. We will be evaluated in terms of our obedience to God's commandments. And so if anyone breaks the least commandment, and teaches others to, he shall be the least in the Kingdom of Heaven. But those who teach God's laws and obey them shall be great in the Kingdom of Heaven.
