There are of course limits to what we as human beings can say about God's activity in the world. The point was not lost on William Sherlock, a seventeenth-century Dean of St Paul's Cathedral in London, with his assertion that we could not hope to discern all of God's mysteries and secrets. We can never aspire to have a comprehensive understanding of the manner in which God acts in the world, but equally this should not push us to the opposite extreme of asserting that God's transcendent relationship with creation simply precludes any meaningful discussion of his action whatsoever. Theologians need to tread a careful middle way between claiming on the one hand that God is limited to those things human beings know and understand, and on the other that we have no relevant knowledge about divine action at all. This difficulty becomes particularly acute given the remarkable advances that the sciences have made in both explaining and predicting natural processes.
