In the form of warm, relaxed letters to a close friend, C. S. Lewis meditates on many puzzling questions concerning the intimate dialogue between man and God. He considers practical and metaphysical aspects of prayer, such as when we pray and where. He questions why we seek to inform God in our prayers if he is omniscient, whether there is an ideal form of prayer, and which of our many selves we show to God while praying. The concluding letter contains provocative thoughts about "liberal Christians," the soul, and resurrection.
