From Geoffrey A. Studdert Kennedy, The Wicket Gate :
Religion leaves a million questions unanswered and apparently unanswerable. Its purpose and object is not to make a man certain and cocksure about everything but to make him certain about those things of which he must be certain if he is to live a human life at all.
Religion does not relieve us from the duty of thought; it makes it possible for a man to begin thinking. It does not put an end to research and enquiry, it gives a basis from which real research is made possible and fruitful of results; a basis without which thinking only means wandering round in circles, and getting nowhere in the end, and research means battering at a brass door that bruises our knuckles, and does not yield by the millionth part of an inch.
