I have read this book, and I have read reviews of the book.
I give it five stars because it confirms in my life in a different way what God tells us about faith.
Having faith is challenging. Loving people is challenging. Everything about faith is not neat, tidy, clean. Faith is messy. Faith is risky. If you are going to church to hear the easy way to God, the answer is, "There is no easy way to God."
McManus labels the thought that faith is easy, clean, tidy, neat as "domesticated."
He challenges you to see your faith in a new way, "barbarian".
If you get what he is saying, then you go act on it.
If you don't get what he is saying, then you put the book aside as different.
No judgments either way.
I liked it because it pushed me, forced me to see my faith from a slightly different perspective than I had seen it before.
