"We always have to answer the question: How can you be so frivolous and selfish to think of anything by the salvation of human souls?" During World War II, C.S. Lewis preached three sermons which were eventually packaged and published along with six others in 1949 as The Weight of Glory and Other Addresses. In this week's episode, Drs. Crystal and David C. Downing discuss the spiritual significance and application of "The Weight of Glory," "Learning in War-Time," and "Transpositions," as well as how they apply to our war-plagued world today.
