I finished "Primal" last night. The book was pretty good. Batterson explores the foundational themes of Christianity in the first century and some of the trademarks of their existence. The book is divided into four parts or sections. Parts one and two were really good. Batterson did a great job, as he usually does, of bringing some historical facts to weave with scripture to allow the point to be well seen. He pointed out the early church's commitment to the spiritual disciplines and to the message of Christ. The last two parts were written in the same vein, but they didn't seem to stand out as much to me.
All in all, it was a good book, as all of Batterson's books are good, but it lacked the pop of his other books like, "In a Pit with a Lion on a Snowy Day," and "All In." I would still recommend it however and I'm sure I'll reread it. The last two parts will probably end up being my favorite!
