Theology is like a map. Merely learning and thinking about the Christian doctrines, if you stop there, is less real and less exciting than the sort of thing my friend got in the desert. Doctrines are not God: they are only a kind of map. But that map is based on the experience of hundreds of people who really were in touch with God--experiences compared with which many thrills of pious feelings you and I are likely to get on our own are very elementary and very confused. And secondly, if you want to get any further you must use the map.
C. S. LewisWe regard God as an airman regards his parachute; it's there for emergencies but he hopes he'll never have to use it.
C. S. LewisThere is nothing like suspense and anxiety for barricading a human's mind against the Enemy. He wants men to be concerned with what they do; our business is to keep them thinking about what will happen to them.
