The Letter to the Hebrews in the New Testament reminds us of that incident, and counsels Christians to make hospitality a Christian virtue. "For you may be entertaining angels unaware." But more than that, you may be doing it to Christ, who said, "If you have done it to the least of these, you have done it to me."

Tom Long teaches at the seminary at Princeton. But for a while he lived in Atlanta, and attended a Presbyterian Church in downtown Atlanta. Like most downtown churches, it has to cope with the problem of the homeless. So they opened up their gymnasium in the winter as a shelter. It was the practice of that church, as it is in this church when we open our buildings as a shelter in the winter months, to have people from the church serve as hosts and hostesses.

Long volunteered to be a host one night. The night came and since no one else volunteered, he invited a friend to come and join him. His friend was not a member of that church. In fact, he wasn't a member of any church. But periodically, in their conversations about religious matters, this friend would say, "Tom, I'm not a theologian, but it seems to me...," and then he would express his opinion.

On this night as they were hosting the shelter, they met the men as they arrived, saw that they had something to eat, hung out with them for a while. Then as the men began to prepare to retire, Tom's friend said, "Tom, you get some sleep. I will stay with them the first watch, then I'll wake you up, and you can come and stay with them for the rest of the night."

So the friend stayed up and mingled with the guests, listened to them, asked questions about who they were, what had happened to them in their lives that they were now homeless. At 2:00 a.m. he went in and woke up Tom. He said, "Wake up! Wake up! I want you to come and see this. Granted I am no theologian, but I think that Jesus is down there."

It was promised. "Those who show hospitality to the least of these," he said, "have done it to me."
