On Mount Sinai, Moses receives the law. God gives instructions for a nation of slaves to become a nation of priests. More than anything, it gave guidance on a life lived with and for the God of the universe. He had rescued them, and now He leads them. The Law given on that mountain shows the people how to live, but also how they won't be able to live. It tills the ground for the cross of Jesus for those of us who see ourselves in the mirror for who we truly are: lawbreakers.
