Following the first three volumes in the series on divine action, this fourth and final volume seeks a prescriptive account of God as an agent. Christian systematic theology raises deep metaphysical questions about the central concepts we use in our thinking about God. One of these central concepts bequeathed by the Christian tradition is that God is an agent. While volumes 2 and 3 offered a wide range of specific divine actions offered in the canonical Christian tradition, the question of how to articulate this basic conviction arises. In this volume, Abraham expounds the concept of God as agent by applying it to various traditional problems in Christian doctrine like the relation of freedom and grace, divine action in liberation theology, the presence of God in the Eucharist, divine providence, the relationship of Christianity and Islam, the relation of the natural sciences to theology and apparent design, and the realm of the demonic. In keeping with the argument of the tetralogy as a whole, specific divine actions are the points of departure for reflection on these topics. The book aims not only to clarify the concept of God as an agent but also to articulate solutions to these traditional problems. It is designed to be the launchpad for further research in divine agency and divine action and how an account of God as an agent can throw fresh light on old theological and philosophical problems.
