In those days there was no king in Israel. People did whatever they felt like doing. Judges 17:6 (MSG)
I still remember some of the substitute teachers that would fill in on a regular basis during my high school years. Most of them were excellent teachers, but there were a few who did not take their jobs very seriously. They did little teaching and cared very little what we did in class. They were like babysitters but with less sense of accountability. The result, of course, was not good. Students did pretty much whatever they wanted and constantly pushed the boundaries to see how much they could get away with.
One of the things I've noticed though the years is that people don't do well without leadership and authority. Given to ourselves, mankind tends to slip into the painful consequences of chaos and anarchy. One of the themes that flows in the subtext of the book of Judges is the free-for-all that resulted from the lack of a central governing authority.
Authority is a good thing, even when we don't always see eye-to-eye.
