Here’s an excellent quote from Grasping God’s Word by J. Scott Duvall and J. Daniel Hays on how to properly approach the interpretation of the Bible:
If you read the Bible merely as great literature, merely for its aesthetic value, or merely for its suggestive moral guidance, not as communication from God, then you can interpret the text in any way you choose. Your main interpretive question will be: What does the text mean to me? If, however, you believe that the Bible is God’s revelatory Word to you and that the Scriptures function as communication from God to you, you should interpret the Bible by looking for the meaning that God, the author, intended. Your interpretive question should be: What is the meaning God intended in this text?
