Among other things that could be said about the bible,
The bible is not a history book, or a how-to manual. The bible is not concerned primarily with setting before us history or pragmatics. The bible is a book of principles. These principles are rooted in historical fact and produce practical result, but the history and practicality are not primary. What is primary? Principles. Or to put it another way, the bible is about doctrine. The bible presents doctrine to us in the form of true principles. This doctrine is the basis of our faith. Sure the bible is historical. Of course the bible is practical. It changes the way we look at history. And it affects every area of our lives–at least it should. But it is only these things because it is doctrinal first.
