Like so many, the first book I read by C. S. Lewis was The Lion, the Witch, and the Wardrobe. I remember the feeling of wonder I felt reading it as seven or eight year old boy, a feeling that I still have when I return to it.
When I became a Christian in my mid-20s and discovered Lewis’s catalogue of reflections on Christianity, I was intrigued by one book in particular. One that I've come back to a number of times. One that, honestly, has been cheapened because of so many homages published on blogs. But despite the tendency of others to ride his coat tails, it’s a book that offers a clever and idiosyncratic look at the obstacles to faith and growing as a Christian.
This is The Screwtape Letters, and it might just be your next favorite book.
