Think of it like this; you have in front of you an amazingly complex machine, unlike anything you have ever seen before, and you want to understand where the machine came from, what the machine does, and how it does it. As you stand examining the machine a man approaches you and says, “This manual was written by the inventor of this machine and explains how the machine works, why it was designed, and how to maintain and repair it.” Being the skeptic that you are, you reject the manual and tell the man that you can figure this all out on your own using “skeptical” methods and your own reasoning. You simply reply, “That manual was written by a man who claims to be the designer, but how can I really trust that claim. I will investigate this machine and tell you all about it once I have studied it thoroughly.”1
I think this quote and article from Answers in Genesis well exemplifies the differences between believers and atheists. Perhaps this is “on average” and not in the total sense of the difference. Some say that only what we agree on socially is what matters. For believers, the written word, as revealed by God, is what matters. So far, I am not impressed in any way by social agreement. But if your starting point is a belief in God, then the manual has authority and is impressive to me.
