Louise suffers from muscular dystrophy. While trying to exit a train station one day, she found herself facing a large flight of stairs without an elevator or escalator. On the verge of tears, Louise saw a man suddenly appear, pick up her bag, and gently help her up the stairs. When she turned to thank him, he was gone.
Michael was late for a meeting. Already stressed from a relationship breakdown, he started battling London’s traffic only to get a flat tire. As he stood helplessly in the rain, a man stepped out of the crowd, opened the boot (trunk), jacked up the car, and changed the wheel. When Michael turned to thank him, he was gone.
Who were these mysterious helpers? Kind strangers, or something more?
The popular image we have of angels as radiant winged creatures is only half true. While some appear this way (Isaiah 6:2; Matthew 28:3), others come with dusty feet, ready for a meal (Genesis 18:1–5) and easily mistaken for everyday people (Judges 13:16). The writer of Hebrews says that by showing hospitality to strangers, we can entertain angels without realizing it (Hebrews 13:2).
We don’t know if Louise and Michael’s helpers were angels. But according to Scripture, they could have been. Angels are at work right now, helping God’s people (Hebrews 1:14). And they can appear as ordinary as a person on the street.
