I run in the path of your commands, for you have set my heart free.
The Ten Commandments represent God’s everlasting and universal moral law. Long before being formally pronounced at Sinai, the moral law was observed in Eden. Even in our fallen world the law has been written upon the conscience of God’s image-bearers. In the age to come that same law will be honored perfectly. In fulfilling the Covenant of Grace through His dying and rising, Jesus did not put an end to God’s moral law but rather to the many ceremonial laws. The Ten Commandments represent God’s expectations for all humanity throughout all time.
For sinners the law can only condemn. That is, by the law, sinners become conscious of their guilt before a holy God. But for God’s people, the law no longer terrifies because our Lord has taken upon Himself the guilt of our own failure to keep it. In Christ we are liberated to view the law not as a means to be made right with God. Rather, having been justified by grace alone through faith alone in Christ alone, we are now free to look upon God’s moral law as a means to live for His glory. Indeed, the Ten Commandments is the law which shows us how to love God and love our neighbor. So, to walk in God’s moral law is to walk in love.
