The illustrations, too vary widely -- from "church Sunday school" pictures of angels from the Renaissance Masters, to more ordiinary drawings of sea captains, cops, lumberjacks, ordinary moms and dads -- depending on the story they illustrate. (If you know "Guideposts", you know the artwork -- otherwise, think "Reader's Digest.")
The purpose of the magazine is not to convert you to anything but, rather, to tell true stories about people who have had encounters with guardian angels. "Belief" is left up to the reader. Some of the angel stories are of the "miracle" type: surviving car crashes, shipwrecks, serious illnesses, etc. Others are of the more "ordinary" type, such as the stranger who is there at the right moment. This fits with the Jewish POV of an angel, since the Hebrew word, malach, can refer either to a supernatural being or an earthly messenger.
Personally, I believe in angels, and I find the stories fascinating. Granted, some of them might strike you as versions of "The Vanishing Hitchhiker." On the other hand, all the stories are first-person, by-lined accounts, often with photos of the people or animals involved. And how do we know the Vanishing Hitchhiker isn't a real angel sometimes?
