Jamie Smith (aka James K.A. Smith), is a charismatic, reformed Christian (yes, they exist!), and a philosopher at Calvin College by trade. He’s incredibly persuasive and fascinating to listen to. I had the pleasure of hearing him speak at a college outside of Pittsburgh a number of years ago and his conversational tone really gave the listener a sense of invitation into an actual…dare I say…conversation (note how deftly he deals with some of the questions at the end).
