Traveling in the desert is dangerous. One may faint from heat or be blinded by light. Caves offer safe shadows. One cannot survive alone. In the desert culture of Abraham and today, when meeting someone you share provisions. Generosity may save a stranger’s life. In our first lesson, God visited Abraham and Sarah in the person of three strangers. Abraham hurried from the tent, invited them to stop and rest in the shade of the tree and then hurried off to prepare a meal and serve them. Hospitality, tonight’s radical practice, is essential in a desert and everywhere. We all need welcome and sharing.
We assume self-sufficiency though most of us experience much need and forget our past. Remember the children of Abraham spent 400 years as resident alien slaves in Egypt. After being rescued and later receiving land, God instructed: “The alien who resides with you shall be to you as the citizen among you; you shall love the alien as yourself, for you were aliens in the land of Egypt”[i] Being a stranger shapes behavior. We know what it feels like. God said: “You shall not oppress a resident alien; you know the heart of an alien, for you were aliens in the land of Egypt.”[ii] Later our ancestors were aliens in exile under Babylonian rule. We know what it is like to be traveling and to be outsiders. Having been strangers, we welcome strangers.
