This collection of essays and letters from C.S. Lewis covers a wide range of topics, including Christmas traditions, miracles, vivisection, morality, dogma, and prayer.
He talks about how a God who is good can allow pain in the world, briefly summarizing concepts from his book "The Problem of Pain." He talks about the common man of his day and their objections or misunderstandings that keep them from believing in Christ. He talks about the decline of religion in Britain, and the Christian truths hidden in pagan mythology. He answers questions, refutes common mistakes of his contemporaries, and responds to criticisms from his fellow intellectuals.

Some of it felt like I was coming into a conversation after the people had already been talking for an hour. Because I didn't hear what the first person said, then I have little or no context for the responses. Since I have not read whatever article or essay was published by Dr. So-and-so, now I am lost reading Lewis' reply to them.
Other things were a bit confusing to me because I am just not familiar with the knowledge or traditions that were widely known in Lewis' day. Thankfully, some of the footnotes explained these things.

I don't always agree with Lewis in his theology, but I always appreciate that he makes me think deeply about a wide variety of subjects.

In many of these essays, he poses a moral question, dances all around it from every perspective, shows how the atheistic or political perspective is wrong, and then leaves it to you to find an answer for yourself. The only obvious option left at the end is Christ, because that's the only thing that makes sense. Lewis leads you right to the edge of the water, but it is up to you to take it that little extra inch and get a satisfying Christian drink of living water.

I skipped the last section of the book which is some of Lewis' letters, because I have already read a much larger compilation of Lewis' letters. I skimmed over them here, and did not see anything new, so I just skipped it for now.

I was annoyed that several of the essay topics repeat themselves. There is an essay about "The Pains of Animals" and another titled "Vivisection" which have almost exactly the same material. Lewis reuses many of the same illustrations for slightly different topics, so it got kind of repetitive.

However, I still enjoyed it because his writing is just so wonderful in every respect. His words are vivid and powerful. His logic just makes so much sense. He leads you clearly from one point to the next so that you can see each link in the chain as you go along.

There is something truly natural and elemental about his arguments. You can look around you at your own life and say, "Ah yes. He described it exactly. Yep, that is the way the world works. That is reality. What he is saying here is true. I can see it every day in our society around us and in how God works in people." It's not like he is spouting some kind of mystical spiritual mystery that I can never understand or observe. He cuts right into the heart of things and clearly shows you the inner workings behind the glitter of the world.
