Believing the Bible is trusting the statements of Scripture at face value, using the normal rules of interpretation that we use for all literature. Yes, the Bible has amazing types and shadows, amazing number patterns, sometimes a layer or two of deeper implications or broader applications, BUT such things don't change the way we interpret the Bible. They are merely enhancement and authentication. The Bible was written with common diction, common grammar, common use of figures, and it must be interpreted with common diction, common grammar, and common figures. Any approach that comes with unique allegorical methods for interpretation must be rejected. It doesn't deserve two seconds of consideration. The allegorical method is a categorical rejection of God's future plans for mankind.
