This book investigates the narrative function of the Old Testament characters in the Gospel of John. The fascinating thesis is that the Hebrew characters in John's narrative uniformly function as a witness for the messianic identity of Jesus. The Jewish scriptural traditions (Hebrew and intertestamental ones) are compared to shed light on John's indebtedness for its formation of his Christology. A compelling argument ensues, which informs our understanding, not only of the Gospel itself, but also of Jesus Christ revealed in the Gospel. COMMENDATION Dr Ahn's thorough and careful study represents a solid contribution, from which many will benefit. All serious interpreters of the Johannine witness will want to refer to this work. - Mark A. Seifrid, Southern Baptist Theological Seminary, USA
