“We are all of us indebted to a vast host of anonymous persons without whom some necessity would not have been available, some good which came to us, we would have missed. It is not too farfetched to say that living is itself an act of interdependence. . .However self-sufficient we are, our strength is always being supplied by others unknown to us whose paths led them down our street or by our house at the moment that we needed the light they could give. . . It is the way of life; it is one of the means by which God activates Himself in the texture of human life and human experience.”
