What is theology all about? In this long-awaited second volume of a multi-volume comprehensive theological system, Norman R. Gulley addresses the foundational question about theology: Who is God? The author starts with the premise that theology is, ultimately, about the essential character of God. What kind of God is he? Is he a good God or a bad one? Gulley’s biblical “cosmic controversy” worldview undergirds his answers to the most fundamental questions of what the Bible teaches about God. Working steadfastly from the platform of sola scriptura established in his Prolegomena, Gulley takes the serious reader on a wide-ranging and insightful tour of the many facets of the doctrine of God. His approach first presents his biblical argument on a given topic, and then provides a helpful survey and summary critique of other views throughout the history of theological and philosophical thought. Beginning with God as relational Trinity, Gulley addresses many other vital questions posed over time, including arguments about timelessness, immutability, and impassability; old and new covenants; God’s revelation through the biblical Sanctuary; His ultimate plan of mediation; redemption and restoration; process and openness theology; predestination; and other topics. As in the first volume, Gulley ranges easily over millennia in showing how different concepts and philosophies have affected our understanding of the character of God. This ambitious work is designed for both the committed student of theology and the general reader who will appreciate each chapter’s opening summary, concise conclusion, and helpful set of study questions. This volume provides the fundamental basis of the rest of the system, and is a paradigm shift from many traditional views about God.
