The central theme of the book is (as the title suggests) the concept of [[angels]] as outlined in the Bible. Dr. Graham was encouraged by the publishers to make this the topic of his next book after the success of his previous one (''[[Unseen (book)|Unseen]]''); he was reluctant to do so for three reasons: 1) he considered the topic to be a "fringe" one, 2) he believed he had covered all there was to say about the topic in a chapter from ''Unseen'', and 3) all his prior books were based on sermons or sermon series he had done, but he had never covered this topic in any sermon series. But he was encouraged to do so by a married couple who were friends (the wife was battling cancer and would pass away before the book was published). | The central theme of the book is (as the title suggests) the concept of [[angels]] as outlined in the Bible.
