Jacobs, a New York Jewish agnostic and father, decides to literally follow the laws and rules of the Bible for one year in order to better understand the relevance of faith in our modern world. He begins by growing a beard. He vows to follow the Ten Commandments. Also he vows to obey the hundreds of lesser known rules such as to avoid wearing clothes made of mixed fibers. He immerses himself in prayer, tends sheep in the Israeli desert, dances with Hasidic Jews in Brooklyn and tells the absolute truth in all situations. Part memoir, part humor, the resulting spiritual journey will leave readers with a fresh perspective on history's most influential book.
