Having a standard does some cool things. For one, it judges our behavior. Can you imagine the injuries if there was no pass interference rule in the NFL? Receivers would be helpless. Secondly, a common set of rules brings a kind of general agreement about how we should live. Generally everyone agrees murder is not acceptable. Thirdly, acceptance of a standard means recognition of some kind of authority, such as the NFL or the American judicial system.
What we see in real life lines up with the biblical account of origins. The Bible says God made us and established the first standard when He told Adam and Eve not to eat of the tree of the knowledge of good and evil. God was the authority. It was up to the first couple as to whose authority they would recognize.
