This accessible, engaging work explores the major theological dimensions of John's Gospel, including God, the world and its people, Jesus, the crucifixion and resurrection, the Spirit, faith, and discipleship. Craig Koester's Word of Life is notable for its comprehensive treatment of themes and its close, careful focus on the biblical text, on the narrative itself. In his introduction Koester provides a succinct overview of the Gospel and shows how disputes about John's theology throughout history have significantly shaped the church and wider society. In the course of his discussion, such expressions as being "born again" and Jesus as "the way" — which evoke both interest and uneasiness today — become much clearer in the context of the Gospel as a whole. Koester interacts with the best of current research and makes creative proposals about how to understand the many aspects of John's theology. His clear and highly readable guide to the theology of John's Gospel will appeal to a wide range of readers.
