Does God act in the world, and if God does, then how? These questions are central questions for Christian theology and Christian mission and ministry. Is God simply a creator who then goes on holiday and leaves the universe to develop, or is God the one who is embodied in Jesus, the God of signs and wonders, death and resurrection? And what does this mean for signs and wonders today, in the life of individuals and local churches? From The Simpsons to a wedding in Cana, from grace to quantum theory, and from the problem of evil to eschatology, David Wilkinson argues that the biblical picture of a God who acts in the world makes sense in the light of modern science, but how God acts cannot be reduced to simple models.
