One of the things that the Satan does is that he convinces us that our current emotional and physical states is synonymous with our reality and it never was different, nor will it ever be different. The way we are now is not the way that we are by nature, nor is it the way that we will be, nor was it the way we were. One of the curses after Adam's sin was the effort that man has to put in to eat. Before the sin, there was no effort needed. The same goes for Torah, you must put in effort to understand it. In the Messianic era, such a thing will no longer exist. The Mashiach will be able to explain everything according to Torah, be able to cure every man on earth from every internal conflict and free him completely.
