Letters to Malcom: Chiefly on Prayer.
Reflections on the Intimate Dialogue between Man and God.
Letter III.
Lewis talks about places, times, and postures to pray. He doesn’t like to pop into a church to pray because invariably there is a distraction. He says before bed is the worst time because you are tired and ready for sleep (certainly true for me). And, he thinks kneeling is good. “You should pray with body and the soul.”
Letter IV.
Lewis ponders the seeming contradiction between prayer and an omniscient God. Why do we even need to pray when God knows everything? That transitions into what should we bring to him in prayer. “I fancy we may sometimes be deterred from small prayers by a sense of our own dignity rather than of God’s."
