5 of 5 stars to The Screwtape Letters by C.S. Lewis
This is some next level temptation insight. I don’t like demons, but I do like snark, so there is a lot to enjoy, even to learn from snarky Uncle Screwtape. Lewis is really good at nailing slippery sinful inner inclinations to the wall, and in this book he does so while also making our spiritual enemies look silly.
