Do you believe in Angels? The world-renowned preacher Billy Graham, who recently died, only a few short months before his own 100th birthday, described this book as 'one of the most fascinating studies of my life'. In it, he explores the biblical basis of what angels are, and the crucial role they play in our lives. Today's interest in the supernatural often seems to put the emphasis on demons, ghosts and other evil powers. But what about the forces of good? Angels are thought by some to be purely the province of song lyrics, fairy tales and popular mythology, yet they are mentioned nearly three hundred times in the Bible and are in fact a very real source of comfort and strength for many people today.
