G-d created the world so it could run on the basis of justice, so that man could perfect himself and create his own World to Come. Justice is nothing more than a creative process that is allowed to unfold and produce certain consequences. If mankind because structurally fragmented, then so does the World to Come, and it needs the activity of many people in order to be developed. The Messianic light should have been revealed to the Jews at Mount Sinai, but they lost the light after the sin of the Golden Calf. The light and the Torah were inextricably linked and when Moshe was begging G-d to still give the Torah even after the sin, he was begging for the Torah to be given in non-Messianic form. It's as if G-d took the Torah and changed it from only a soul to a body and a soul.
