We read this book as a Church life group for our lent study, and I thought it was great. The discussion questions were perfectly crafted for getting conversation started and then diving deeper into the text, and referencing other relevant Bible passages too.
We had some fantastic discussions in our group using this material, until Coronavirus meant we had to stop meeting, and I actually did the last couple of sessions alone.
To me, this really proved the value of this as a discussion based study book, because I got nowhere near the same value from the last two sessions with having no discussion to help go deeper and learn more.
I’d definitely check out more books in this series for further study though, and I also think these could be really well adapted for use with our youth group too.
