How does God relate to the world? What difference does our understanding of God make for conceiving of God's relation to us? Christian theology has seen a flourishing of activity in response to these questions under a common doctrinal theme: Trinity. That said, proposals for understanding how God relates to the world through the Trinity of God's being—otherwise known as the relationship between the immanent and the economic Trinity—vary significantly. This book, reflecting on the work of four modern theologians—Dorner, Barth, Pannenberg, and Jenson—offers a set of constructive proposals on key issues relating to the God-world relation, including a way to understand divine immutability without denying God's living history with others and a trinitarian notion of divine sovereignty that demonstrates how God transcends history from within the structures of time. At each step along the way the author conveys how Trinity opens up a richer, more expansive conception of God's relation to us. This book shows how Trinity serves the practical work of theology as faith seeking understanding.
