Andreas J. Kostenberger's new commentary on the Gospel of John draws on extensive research and engages the best of contemporary scholarship, yet provides a readable study that will be beneficial to students, pastors, and scholars. After considering the historical context of the letter as well as its relation to other New Testament writings, Kostenberger turns to his exegetical work. An introduction to each exegetical unit is provided along with the author's own translation of the Greek text. In the course of his verse-by-verse comments, Kostenberger incorporates references to other ancient writings that help explain the book's theological, cultural, and social context. Where appropriate, he draws upon the work of other commentators and provides extensive notes for further reading and research.
