A Theology of John's Gospel and Letters introduces the first volume in the BTNT series. Building on many years of research and study in Johannine literature, Andreas Köstenberger not only furnishes an exhaustive theology of John's Gospel and letters, but also provides a detailed study of major themes and relates them to the Synoptic Gospels and other New Testament books. Readers will gain an in-depth and holistic grasp of Johannine theology in the larger context of the Bible. D. A. Carson (Trinity Evangelical Divinity School) says about Köstenberger's volume that "for the comprehensiveness of its coverage in the field of Johannine theology (Gospel and Letters), there is nothing to compare to this work." I. Howard Marshall (University of Aberdeen) writes, "This book is a 'first' in many ways: the first volume that sets the pattern for the quality and style of the new Biblical Theology of the New Testament series published by Zondervan; the first major volume to be devoted specifically to the theology of John's Gospel and Letters at a high academic level; and the first volume to do so on the basis that here we have an interpretation of John's theology composed by an eyewitness of the life and passion of Jesus." The Biblical Theology of the New Testament Series The Biblical Theology of the New Testament (BTNT) series provides upper college and seminary-level textbooks for students of New Testament theology, interpretation, and exegesis. Pastors and discerning theology readers alike will also benefit from this series. Written at the highest level of academic excellence by recognized experts in the field, the BTNT series not only offers a comprehensive exploration of the theology of every book of the New Testament, including introductory issues and major themes, but also shows how each book relates to the broad picture of New Testament theology.
