C.S. Lewis's book Mere Christianity examines the nature of Christianity and how it contrasts with other worldviews. Lewis argues that Christianity is not simply a set of rules or a system of morality, but a relationship with a God who is a "dynamic, pulsating activity" rather than a static being. He asserts that the human experience of morality is an indication of a higher, universal moral law and that humans are ultimately incapable of achieving goodness on their own. Lewis explores the central Christian doctrines, including the Trinity, the atonement, and the concept of "becoming" a Son of God. He contends that true Christian living involves a complete surrender of the "natural self" to Christ, allowing for the transformation of the individual into a new, spiritual being.

A true Christian classic.
