Longtime professor at Concordia Seminary--St. Louis, William F. Arndt, wrote numerous books and articles on "Bible difficulties." These works focused on disabusing people of the notion that the Bible contained errors, showing that with calm logic and careful investigation one could resolve most alleged discrepancies, or, even when the resolution surpassed our knowledge or insight, that this did not necessitate or prove a contradiction. Sometimes a fair evaluation was one that might not be able to settle upon a single resolution, but had to leave several possibilities open. Arndt's purpose was to both dismiss alleged proofs of inaccuracies or mistakes that skeptics clung to and to lead believers to trust in the reliability of the Scriptures and have humility when approaching God's Word.
