Some see the Bible as some sort of instruction manual on how to live a supposed good life.  Somehow, the Bible serves as a backup proof text for all the great questions in life.  A biblical response is either good or bad, not subject to argumentation.  You can only discuss the text.  Putting your life and belief system in the Bible means that you are trumping every other argument.  “The Bible tells me so” ends the discussion and the argument.  You can only agree, disagree, or argue about the meaning of the text, if your morality is based on the Bible.
