What's the Point of Prayer?

"Creation seems to be delegation through and through. He will do nothing simply of Himself which can be done by creatures." Those words were written by C.S. Lewis in Letters to Malcolm: Chiefly on Prayer at the end of his life and published posthumously. In this fifth installment of "Love, Pain, Grief, and Joy," Drs. Crystal and David C. Downing, along with Producer Aaron Hill, explore this often overlooked book by Lewis. How did Joy's death inspire Lewis to write this book? How and why should it be read in conjunction with A Grief Observed? And how does this book that is "chiefly on prayer" still manage to touch on broader theological topics such as joy, embodiment, resurrection, determinism, free will, organized religion, and the impassibility of God.
