Dr. William Lane Craig says the atheist need not approach the Bible as inerrant or inspired by God to get to the truth of it.
This is consistent with the way I came to regard Jesus Christ as true. That is, I began reading the Bible as literature – not as the divinely-inspired word of God. The set of documents we call the New Testament make a compelling case for Christ as 1st-century historical records alone without having to be regarded as the word of God. I make this clear in the post I Invite You to Challenge Me at My Most Vulnerable Point.
