It seems to me that one of the things we most fear is the stranger. And at most times in human history, most people have lived among people who are mostly pretty much the same as themselves. Today, certainly in Europe and perhaps even in America, walk down the average Main Street and you will encounter in ten minutes more anthropological diversity than an 18th-century traveler would have encountered in a lifetime.
So you really have this huge problem of diversity. And you then go back and read the Bible and something hits you, which is we’re very familiar with the two great commands of love: Love God with all your heart, all your soul, and all your might; love your neighbor as yourself. But the one command reiterated more than any other in the mosaic box — 36 times said the rabbis — is love the stranger for you were once strangers in the land of Egypt. Or to put it in a contemporary way, love the stranger because, to him, you’re a stranger. This sense that we are enlarged by the people who are different from us — we are not threatened by them — that needs cultivating, can be cultivated, and would lead us to see the 21st century as full of blessing, not full of fear ….
You can find God in the other side.
