In 1975, Billy Graham recognized there was little teaching available for the modern Christian on the subject of angels, so he wrote a book on the topic. The book, Angels: God’s Secret Agents, explores the reality of angels and their roles.

In the preface, Rev. Graham shares what first led him to write the book:

“When I decided to preach a sermon on angels, I found practically nothing in my library. Upon investigation I soon discovered that little had been written on the subject in this century. This seemed a strange and ominous omission. Bookstores and libraries have shelves of books on demons, the occult and the devil. Why was the devil getting so much more attention from writers than angels? Some people seem to put the devil on a par with God. Actually, Satan is a fallen angel. Even when people in our modern age have had their attention drawn to the subject of angels from time to time, those ideas have often been fanciful or unbiblical.”

Billy Graham addresses the reality of angels in the book’s second chapter, appropriately named “Angels Are for Real”:

“Speculation about the nature of angels has been around long before Queen Victoria’s time, and it continues down to the present time. Yet through revelation in the Bible God has told us a great deal about them. For this reason, theologians through the ages have universally agreed about the importance of “angelology” (the orderly statement of biblical truth about angels). They judged it worthy of treatment in any book of systematic theology. They wrote at length, distinguishing between good angels and satanology (the study of fallen and thus evil angels). But today we have neglected the theme of good angels, although many are giving the devil and all of his demons rapt attention, even worshiping them.

Angels belong to a uniquely different dimension of creation that we, limited to the natural order, can scarcely comprehend. In this angelic domain the limitations are different from those God has imposed on our natural order. He has given angels higher knowledge, power and mobility than we. Have you ever seen or met one of these superior beings called angels? Probably not, for both the Bible and human experience tell us visible appearances by angels are very rare—but that in no way makes angels any less real or powerful. They are God’s messengers whose chief business is to carry out His orders in the world. He has given them an ambassadorial charge. He has designated and empowered them as holy deputies to perform works of righteousness. In this way they assist Him as their creator while He sovereignly controls the universe. So He has given them the capacity to bring His holy enterprises to a successful conclusion.
