The Bible is thought of as authoritative on everything of which it speaks. And it speaks of everything. We do not mean that it speaks of football games, of atoms, etc., directly, but we do mean that it speaks of everything either directly or indirectly. It tells us not only of the Christ and his work, but also of who God is and whence the universe has come. It gives us a philosophy of history as well as history. Moreover, the information on these subjects is woven into an inextricable whole. It is only if you reject the Bible as the Word of God that you can separate its so-called religious and moral instruction from what it says, e.g., about the physical universe.
