We live in a culture that increasingly questions authority, truth claims and inherited belief, so the question presses: what are we to make of a book thousands of years old that claims to speak for God? John MacArthur addresses the trustworthiness of Scripture directly - its inspiration and inerrancy, the reliability of its transmission, its unity across sixty-six books and many centuries, its fulfilled prophecy, and how it differs in kind from the sacred texts of other religions.

MacArthur writes briefly and plainly here, without the apparatus of a technical apologetic, which makes the book usable as a gift to a doubting friend or a new believer, and as a refresher for Christians who hold the Bible's authority but have never had to defend it. The aim throughout is not merely to win the argument but to send the reader back to the book itself with confidence.
