Is the Bible, the most influential book in world history, still relevant? Why do people dismiss it as being irrelevant, irrational, immoral, or all of these things? This explanation of the Book of Deuteronomy, the fifth book of the Bible, will demonstrate how it remains profoundly relevant—both to the great issues of our day and to each individual life. Do you doubt the existence of God because you think believing in God is irrational? This book will cause you to reexamine your doubts. The title of this commentary is The Rational Bible because its approach is entirely reason-based. The reader is never asked to accept anything on faith alone. In Dennis Prager’s words, “If something I write is not rational, I have not done my job.” The Rational Bible is the fruit of Prager’s forty years of teaching to people of every faith and no faith at all. On virtually every page, you will discover how the text relates to the contemporary world in general and to you on a personal level. His goal: to change your mind—and, as a result, to change your life.
