The more the Jews sin, the darker the world gets and the more hidden G-d becomes. The Mashiach ben Yosef will reveal the Torah in its entirety, and the Mashiach ben David will elevate it to its highest level of revelation before the World to Come. G-d gave us the World to Come on the condition that we earn it. Who represents justice in the world? What is the Satan's role in the world? What will happen to the Satan in the Messianic era? What power will he hold - or not?
