Who or what deserves our allegiance? Our heart? An external morality handed down by our parents or Christendom? Our intellect or science?

Join Drs. Crystal and David C. Downing in this week's episode as they explore the context and message of Lewis's book as well as its proper application to our modern world—viz., how can we avoid becoming "Men Without Chests."
