The religions of the world have at least one thing in common – rules. Rules, laws, and regulations all provide a neat system of things we ought to do and things we ought to avoid. They help keep everybody on the same page and moving towards a shared goal. A common rule fosters unity. And when we speak of improving our lives and becoming better people, it is easiest to follow a set of rules. So often we want to boil it down to identifying exactly where the line is that we must not cross. When it comes to religion, rules are king.
