"You must not add anything to what I have commanded you or take anything away from it..."
When we follow Israel we see the ups and downs that they go through in their service to God. There is a constant fluxuationg of commitment to their service to God. Yet God, through his Law in the Old Testament is the foundation for the nation of Israel to know that they are living to worship their God. Through God's understanding of humanity he creates a foundation for the nation of Israel to be a near to their God unlike the gods of the nations around Israel. The nation of Israel was to be a beacon of hope to the people around them by they way that they kept the Law of God.
When I apply this text to my own life I begin to see why I also need to be founded upon God and not what I want. There are often various things that I would want to do and without the foundation of the Law I would not truly understand what God wanted me to do. It would be difficult to know what is right or wrong. I know that through Jesus the Law has been fulfilled but the Law still has a function that, "through the law comes knowledge of sin" (Romans 3:20b). I need to know the law so that I can know truly how far from God I am so that I can see my need for Jesus.
God help me to not add or take away anything you have spoken. Help me to yield to what you have to say no matter what I might want. Amen.
