Ecclesiastes is an Old Testament book with a long history of diverse and contradictory interpretations. Even basic questions -- who wrote the book, when, and for what purpose -- perennially plague scholars. The book's theological message is likewise elusive, hidden in riddles and convoluted trains of thought that twist and turn back upon themselves. In this expert commentary on Ecclesiastes, Peter Enns neither disregards nor attempts to resolve the book's many theological tensions and ambiguities. Rather, he shows how these form the backdrop against which the author struggles to show readers the proper path forward in their journeys of faith -- remaining true to the tradition to "fear God and keep the commands" despite the apparent futility of human existence.
