by C. S. Lewis
This is a classic, relevant before it was even published as a book, and relevant ever since, with eternally relevant questions for non-Christians and immediately relevant reminders for believers. You should read it.
I’d known about the book for a long time but had never read it. Then, a few weeks ago when war started (again) between Russian and Ukraine, I saw on the tweetstream someone mention that he had started reading Mere Christianity, and I remembered that Lewis originally prepared most of the material for the book as he shared it over a radio broadcast series in England during WW II. Similar contexts, then and now, made now seem like the right time for me to pick it up.
I didn’t realize how many Lewis-ian ideas came from Mere Christianity. This is where the “Lord, Liar, or Lunatic” apologetic comes from. It’s where he says, “the Christians who did most for the present world were just those who thought most of the next” and “Aim at Heaven and you will get earth ‘thrown in’: aim at earth and you will get neither.” It’s where he quotes George MacDonald that as a Father “God is easy to please, but hard to satisfy.” And it’s where he talks about how men who try to be original can’t be, but “if you simply try to tell the truth (without caring twopence how often it has been told before), you will, nine times out of the, become original without ever having noticed it.”
I don’t agree with Lewis (because I disagree with his reading of the Bible) on the degree of freedom in man’s will, and he is wrong (again, according to Scripture) about how some “people in other religions … [can] belong to Christ without knowing it.” While these false things can’t be ignored, they are, ironically, defeated by so many of the true things that Lewis says.
God is killing our need to be needed, and He is doing more than making us “nice,” He is making us new men. Mere Christianity will edify and fortify such men.
