We do this now as well. We make our own rules and regulations, our own boundaries – designed to keep “others” out and make us feel superior, part of the club. In short, we are just as guilty as the Israelites were.

Paul refers to Moses for a description of the law we need in Romans 10:8:

The word that saves is right here,
as near as the tongue in your mouth,
as close as the heart in your chest.

I really think that God was trying to tell us (through Moses) that the law we need is not written in a book, but written upon our very souls. We are born with it. We die with it. Our choice is whether we live with it.
