Prayer is a pure gift, a great gift from God. Lewis understands it that way too. With his usual brilliance, he uses his correspondence with another intellectual to shed light on questions such as: What is the value of prayer? Is it a soliloquy that no one hears? Does it make sense to pray for the dead? Why is liturgy important?
In his arguments, Lewis shows vigorous conviction and, at the same time, great sensitivity and understanding of human weaknesses and fears.
