C.S. Lewis’ masterpiece Mere Christianity, which was adapted from a series of radio talks he gave in the 1940s, is both a convincing case for the truth of Christianity and an important reminder of its importance in our own lives. Preferring to forgo denominational debates and dogmatism, Lewis instead offers a case for the basic, essential tenets of the Christian faith.
Lewis accomplishes so much in this valuable book. To start off, Lewis establishes the existence of God via a convincing presentation of the Morality Argument. He argues that humans all have a basic moral code which we know that we should follow but which we know we fail to follow. God, argues Lewis, provides the explanation for this prescriptive moral law that we find ourselves obliged to obey. Near the end of the book, Lewis delves into the more difficult topics of theology including the nature of the Trinity and God’s relationship to time. He handles these difficult topics remarkably well with his engaging style of writing.
But more than providing a convincing case for the truth of God’s existence and Christianity, Lewis also provides a very powerful explanation of morality. He discusses moral issues that are relevant both for people in general and for Christians in particular. These chapters about morality are simply excellent. Even though they aren’t apologetic in nature, I found Lewis’ exposition of morality very useful and so persuasive that I think it will have a positive impact on my own life. Near the end of the book, Lewis gives a very convicting argument for the importance of taking Christianity seriously.
Mere Christianity is easy to read, and Lewis’ style of providing simple analogies makes complicated topics intelligible and interesting. It may not be a heavily referenced or scholarly tome about Christian apologetics, but it is a convincing, clear, and simple defense of mere Christianity and of Christ’s importance in our lives. Overall, Mere Christianity is a fantastic book that everyone, believer or unbeliever, should read.
