In recent years religion has had bad press worldwide, with the rise and decline of New Atheism, continued secularisation, and the rise of religious fundamentalism, particularly in the context of militant forms of radical Islam. But, before rejecting all religion as bad, dangerous or deluded, we should step back from what might turn out to be short-term controversies, try to adopt a broader perspective, and take a calmer and more rational look at religion. With this in mind, this ebook explores the nature of religion and the place and role of God in religion. It then looks at the origin and development of religion, and offers an overview of the benefits of religion. It closes with a consideration of the decline of organised religion.
