" Iehuda allowed his mind to follow, across the map of the wide world, across the empires and kingdoms that fought and tried to rule and subdue each other. And he imagined what might happen if these words traveled from mouth to mouth, from mind to mind, from one city to the next to the next, if this simple message- love your enemy- were the accepted creed of all the world. He did not see how it could happen.
"If one man went against it," he said at last, "the whole thing would be broken. In a world like that, a world of peace, a world of soft people with no knives, one man could destroy everything."
"Then we cannot rest until every man has heard it. Think," said Yehoshuah softly, "what shall we use up our lives for? More war, like our fathers and their fathers, more of that? Or shall we use ourselves for a better purpose? Is this not worth your life? "
