This is a very interesting, easy to understand summary of what Christianity means and how it compares to other religions of the world. It is on a par with C. S. Lewis's series of radio broadcasts that became his important book, Mere Christianity. Tom Wright is engaging, friendly, and even (as my wife says) cuddly in his explanation of the history and teachings of the church. If you want to understand more clearly what Christians believe and why, this series of talks is the best way to get started.
