"Books," said St. Augustine after his conversion, "could not teach me charity." We still keep on thinking they can. We do not realize ... the utter distinctness of God and the things of God. Psychology of religion can not teach us prayer, and ethics cannot teach us love. Only Christ can do that, and He teaches by the direct method, in and among the circumstances of life. He does not mind about our being comfortable. He wants us to be strong, able to tackle life and be Christians, be apostles in life, so we must be trained by the ups and downs, the rough-and-tumble of life. Team games are compulsory in the school of Divine Love -- there is no getting into a corner with a nice, spiritual book.
