In Miracles, C.S. Lewis makes the case for the titular events by first explaining how there must be something more than nature or "the whole show" and then detailing why that something more is a benevolent being and why it is likely that he would intervene with nature after creating it. The book is similar to Mere Christianity in that it progresses from an agnostic to a fully Christian world view but is nonetheless valuable as it adresses those events which embody the soul of Christianity in a more advanced way. All the major miracles of the new testament are treated; with the Incarnation (wherein God becomes man) playing the central role. Also included are two appendices which deal with matters of free will and the value of prayer.
