 Hebrews 13.2, do not neglect to show hospitality to strangers, for thereby some have entertained angels unawares. You know, that person you helped, that person that you gave some food to, the homeless guy. I can think of a number of times when I've looked back in my life and I thought, could that have been an angel? One time I was in Mexico City. This is in 1979. I spent like a month down there, that visit.
