Life is supposed to be simple.
We're supposed to live by two pages of rules. And there really aren't too many words on those pages.
The two pages were actually stone tablets. Each tablet contained five Commandments. They advise us about ethics, with instructions to worship only God and to keep the sabbath. They also warn against idolatry, blasphemy, murder, theft, and adultery. That's not too bad, really. All of it makes sense, and so it should be a piece of cake.
Then we have the Bible, which makes things more complicated.
