Let's Bust a Recap : Mere Christianity

Mere Christianity began as a series of radio talks C.S. Lewis gave during World War II while he was at Oxford. He was invited to give these talks by James Welch, the BBC Director of Religious Broadcasting, after he read Lewis' book The Problem of Pain (which I have not read yet but it's a strong contender for my 2019 book list). The talks were gradually published in three separate pamphlets entitled Broadcast Talks (in 1942), Christian Behaviour (in 1943), and Beyond Personality (in 1944). Later, all these talks were put into the single volume we now know as Mere Christianity, easily one of the most influential theological works of the last century. In these talks, Lewis succeeded in defending Christianity and explaining its fundamental beliefs. He chose to avoid denominational controversies and focused instead on what core beliefs all Christians have in common. 

This was my first time actually reading the complete book, cover to cover. I've started it several times (there was still a bookmark in there from a previous attempt). I've read excerpts, quotes, even full essays. But this was the first time I started from the beginning and read to the end. And, unsurprisingly, I found Mere Christianity to be an invaluable resource. Lewis was the master apologist, and it never ceases to amaze me how he could use the most mundane objects or activities in the most beautiful and helpful spiritual analogies. Lewis wrote for every man, and that is what makes his writing so profound. He wrote for the bricklayer and the philosopher, the ditch-digger and the intellect. As I was reading Mere Christianity, it was clear, it made sense, it seemed simple. And yet I know that if I tried to articulate or defend my beliefs in the way that Lewis did, I would trip over my tongue. Reading books like Mere Christianity make me thankful for men and women like C.S. Lewis who broaden my understanding of spiritual matters and give me resources I can pass on to others. I cannot recommend this book highly enough, and, much like The Weight of Glory, this book instantly earned a spot on my "To Re-Read Again and Again" list. 

What's your favorite non-fictional work of C.S. Lewis? I've still got a ways to go, but what should come next? As mentioned above, I'm really leaning toward The Problem of Pain but how do I choose?
