I’d love to show hospitality to angels, invite them to dinner and let them sleep in the guest room. Who wouldn’t?
Trick is, I won’t answer the doorbell and find an angel on the front stoop. Angels tend to show up incognito.
Hebrews 13:2 (ESV)
Do not neglect to show hospitality to strangers, for thereby some have entertained angels unaware.
Apparently, God wants us to view strangers as potential angels.
