Short Review - This isn't a bad book. I actually like it. But if you have read much of Wright previously then this is mostly repeat. It is a re-issue of a 1978 book and then it was a collection of his earlier sermons. It is surprising how many of his main ideas are here, but they are not as fully developed as later books. So while it is a decent intro to Wright, it is not as good as some other books of his. And its biggest weakness is that it isn't tightly organized, so it feels like a bunch of disperate sermons more than a cohesive book.
