I agree with the earlier four reviewers: this is a fine summary of these major world religions: Hinduism, Buddhism, Confucianism/Taoism, Judaism, and Islam. Cooper gives the basic history, beliefs, writings, and worship practice of each of these religions.
The book has many helpful charts, study questions, project suggestions, website resources, and book suggestions for further study. I really appreciate how this book is laid out. Furthermore, Cooper is kind in his assessments; he doesn't critique these religions in an arrogant way. There are many strengths in this book.
However, I do have to point out one big weakness: the last chapter (entitled "Theological Responses to Other Religions"). In this chapter, Cooper talks about inclusivism (Jesus saves people outside the Christian faith), exclusivism (Jesus saves only those who believe in him), pluralism (all religions are legitimate), universalism (Jesus will save everybody), and particularism (a newer hybrid position). He says that all of these views are acceptable in Christianity. Cooper himself leaves them all as viable options, and does not really speak for or against any of these positions. I believe that the most biblical view is Jesus saves only those who trust in him (exclusivism), and that the other views are quite unbiblical. All of these positions cannot be correct, and it's not helpful to say they are equally valid and leave the chips fall where they may. It's disappointing to find this approach in a book related to apologetics and evangelism. I'm guessing those who are so-called exclusivists like myself will be discouraged by the final chapter.
In summary, the first six chapters are good, the seventh one is not. I recommend the first six chapters, but cannot recommend the final one. It's a good summary of these major religions, but it ended in a fizzle. So the book is worth getting, certainly. But read that last chapter with discernment.
