Make good use of it / everyday life

Ludwig Wittgenstein wrote to a recent recipient of a doctorate of philosophy: "May you make good use of it! By that I mean: may you not cheat either yourself or your students. Because, unless I'm very much mistaken, that's what will be expected from you." Seems to me that with only slight changes in terminology this exhortation would apply quite nicely to a recent recipient of a masters in divinity. He also wrote, in a letter to a friend, "What is the use of studying philosophy, if all that it does for you is to enable you to talk with some plausibility about some abstruse questions of logic, etc. and if it does not improve your thinking about the important questions of everyday life?" Once again this could easily apply, mutatis mutandis, to the study of theology in many quarters. On this point I always appreciated my New Testament professor, Jo-Ann Badley, as she tried to push us to ask the question, "How does it preach?"
