Apologetics Through Literature

This looks like a very fascinating series of lectures by Alister McGrath on how the Christian might use literature "to explain and defend the gospel."� I'm particularly interested in lectures 3a and 3b where he discusses the apologetic use of the writings of C.S. Lewis and Tolkien. Laurence O’Donnell writes:

"Dr. Alister McGrath, professor of historical theology at Oxford University, has released free audio lectures from Wycliffe Hall’s summer school program. These fascinating lectures begin by briefly defining Christian “apologetics” and then proceed to pithy presentations on using various genres of literature apologetically. With British wit and humor Dr. McGrath explores the question, 'In what ways can Christians use literature to explain and defend the Gospel?'"
