In G-d We Trust
Yaakov Avinu is on his deathbed. He gathers his children to him and is prepared to reveal to them their future. What he actually does is bless them; he does not tell them about what will happen "in the end of days".

Commentaries suggest different answers to this turn of events. Rashi says - based on the Gemara and Midrash- that the Sh'china (Divine Presence) left Yaakov and he no longer possessed the power of prophecy. It seems reasonable to suggest that G-d did not want Yaakov's sons - nor us, their descendants - to know with certainty how Jewish History would unfold, perhaps because this would take a lot of the trust, faith, belief, confidence in G-d away from us. The thinking is: if we know with certainty the outcome of something, then that knowledge either dictates our actions, or convinces us that our actions are irrelevant. Either way, the kind of life that G-d gave us goes out the window. How do we know that there will be a Complete Geula within eternal Beit HaMikdash, with a recognition on the part of the nations of the world of the One G-d of Israel and of Israel's role in this world?

We do not know that because Yaakov Avinu told his sons and they their sons and they us. We KNOW it because it is part of our Belief. And our belief is with a complete heart and mind.

To be sure, with the children of Yaakov stuck in Egypt and facing a deterioration in their condition, it would be nice to know how long it will last and how it will end. But "nice" isn't the issue here - living life according to G-d's Will is.

Or, let's look at it this way. G-d's knowledge is not like ours. If that knowledge is not transmitted to us, then we have the potential to shape and reshape our own lives, futures, destiny. Denying us the knowledge of what will happen, challenges us to maximize our chances for a good future and can hasten the Geula.
