[What is #OctTBR2022? I explain it here.]
What It Is: A 400-year-old allegory of the Christian life, written by an evangelical minister while he was imprisoned for not conforming to the state-mandated religious regulations.
Why I’m Reading It: I’ve read this book a few different times in my life (as you can tell by my much-worn copy of it), and every time I feel like I gained from it. It’s been about 8 years since my last reading of it, so I feel like I’m about due. It’s a pretty divisive choice, even among conservative/reformed evangelicals; some folks love it, while others just don’t enjoy it at all. I’m in the “love it” camp. (If you don’t enjoy it personally, I would suggest trying this outstanding dramatized version in podcast form.)

Do you read both parts? It seems a lot of people only read the first part. Let me know!
I love the second part, and it includes one of the most relatable characters in the story for me. In fact, I wrote about it years back: https://medium.com/publishous/on-fearing-and-hope-dc90f5b8e44d
I should see about republishing that essay on here, come to think of it.
