The sermon explores the reliability of the Bible by examining three tests applied to ancient documents: internal consistency, external corroboration with historical facts, and bibliographic integrity. It argues that the Bible passes these tests, demonstrating its internal coherence, alignment with archaeological discoveries and non-Christian historical accounts like those of Tacitus and Josephus, and boasting a remarkably well-preserved textual history with numerous early copies. The speaker emphasizes the meticulousness of ancient scribes and encourages listeners to trust the Bible as a reliable source of truth, contrasting its textual preservation with that of other ancient works and highlighting the importance of examining evidence with honesty and discernment.
