Weizsäcker’s book The World-View of Physics is still keeping me very busy. It has again brought home to me quite clearly how wrong it is to use God as a stop-gap for the incompleteness of our knowledge. If in fact the frontiers of knowledge are being pushed further and further back (and that is bound to be the case), then God is being pushed back with them, and is therefore continually in retreat. We are to find God in what we know, not in what we don’t know; God wants us to realize his presence, not in unsolved problems but in those that are solved… . God is no stop-gap; he must be recognized at the centre of life, not when we are at the end of our resources; in health and vigour, and not only in suffering; in our activities, and not only in sin. The ground for this lies in the revelation of God in Jesus Christ. He is the centre of life, and he certainly didn’t ‘come’ to answer our unsolved problems.
