- Can what the book says be supported by the Word of God?
- Is the book internally consistent? That is does the author not contradict himself in the presentation of his point of view?
Books are like those who are traveling through our spheres of influence with a message. We are to check them out like the Bereans did with Paul, Acts 17:11. Further we are to evaluate them based on Isaiah 8:20. If they do not reflect the truth of the Word, they were written in the dark.
