Tim Keller founded Redeemer Presbyterian Church in NYC in 1989. Over the course of his quarter century as its pastor the church and Keller - unapologetically classical in its theology - rose to a place of influence in the midst of Manhattan. Dave reflects on his engagement with Keller and why he was so influential. In the second half the tables are turned from an learner episode where Mike quizzed Dave on Billy Joel's original "We Didn't Start the Fire" and now it is Mike being quizzed on Fall Out Boy's updated version. Warning, the song is terrible and this part of the show is far too long.
