The principles for interpreting the Bible are no different from the principles man has used throughout time when seeking to understand the meaning of any writings.
An axiom is a self-evident truth, a statement accepted as true for the sake of argument. Given the truth of an axiom, certain logical statements, or corollaries, can be drawn.
One self evident truth is the Bible is a book and it's written in languages spoken by people who wanted to communicate ideas to their readers. From this axiom a logical statement can be drawn that each Biblical writing, each word, sentence, and book, was recorded in written language and followed normal, grammatical meanings, including figurative language. Since it was written in the languages of the people (Hebrew, Aramaic, Greek), it didn't have to be decoded or translated. Those who read it didn't have to read between the lines for something other than the normal meaning. This suggests that we shoudn't read the Bible with preconceived notions or ideas, but instead should let the Bible speak since it follows a normal literal method of interpretation.
For example the Old Testament prophesied that Christ would be born in Bethlehem (Micah 5:2), that He would ride on a donkey (Zech. 9:9), that He would be punished for our sins (Isa. 53:4-8). He did all those things just as literally predicted.
This corollary also suggests that the goal of Bible interpretation should be to determine the original meaning of the text. If one person can make the Bible say one thing and another is allowed to make it say something else with neither being derived from the actual statement of Scripture, we destroy the ability of the Bible to communicate as a normal piece of literature.
