Before giving the Torah to the Jewish People, G-d offered it to all the other nations of the world. Each one refused. A new entity was created at Mount Sinai, an entity that never existed before; a man that had no capacity to create the World to Come - a goy. What is a Jew? An individual with the capacity to convert this world into the World to Come. It was not until the giving of the Torah on Mount Sinai that a segment of the world's population had that power stripped from them, and became the goyim. What is the impact of this on all the future workings of the world?
