There is something about an election season that tends to focus the mind on the problems in the world and, for many of us, cause us to feel uneasy. We may try to blame this anxiety on the state of the world, but there must be something more to it. We have a sense that something is truly wrong, as if objective standards are being violated.
In a BBC broadcast from August 1941 (which would later become a chapter in the book Mere Christianity), C.S. Lewis explains why we have reason to be disturbed: because there exists a Moral Law, because there is a Mind behind this Law who expects us to act in a particular manner, and because we have all fallen short of meeting this expectation.
