I can understand how someone might be thrown off by how this is categorized. Most Christian bookstores I’ve been to don’t even carry the book, much less have a category for it, probably for the exact reasons you’ve cited. But I think the reason a lot of secular bookstores stock it in the Christian Inspiration section is because it is a book for, well, the REST of us. Many of the books that are typical of this genre I struggle to be truly “inspired” by because of the level of loftiness and reverence that I find unrelatable. My own personal walk is often irreverent, faulty, and, to say the least, difficult. It’s people like me that Lamott is speaking to. She gives her readers a very personal look into the extent of God’s grace and compassion. She shows us through her account that it is not vocabulary, lack of vices, or any other secondary behavior that makes us acceptable to God. He takes us and loves us and desires us along with our multitude of flaws and swear words. It is in her story of learning to accept and reciprocate His love that wretches such as myself find true inspiration.
