A good many people nowadays say, “I believe in a God, but not in a personal God.” They feel that the mysterious something which is beyond all other things must be more than a person. Now the Christians quite agree. But the Christians are the only people who offer any idea of what a being that is beyond personality could be like. All the other people, though they say that God is beyond personality, really think of him as something impersonal: that is, as something less than personal. If you are looking for something super-personal, something more then a person, then it is not a question of choosing between the Christian idea and the other ideas. The Christian idea is the only one on the market.
