Chasidut sur Isaïe 2:11

The proof of this is the world as it will be in the time to come, "the world that is entirely Shabbat, [where] the righteous sit with their crowns on their heads" (Berachot 17:a), and none but God will be exalted on that day (Isaiah 2:11). Certainly that world is at a higher [spiritual] level than the world is now, and such an event/reality certainly is better than its absence. So why did the Holy One Blessed Be He not begin with this, [but rather arrange it so that] all this must come at its own era and time - just as Shabbat comes only after the six profane days? In regard to the creation of the world, even though the Holy One Blessed be He knew that its existence was better than its absence, nonetheless, He placed His Will in opposition to His [fore]knowledge and so made this [present world] come first. Though he knew that this act [creating the world in an ideal state] was good, still He desired to not bring this about until its appointed time. So He ignored His knowledge and followed His will. That which preceded creation can be likened to the world that is entirely Shabbat, and this is as the verse says (Kohelet 3:11) He brings everything to pass precisely at its time, even the world [this is reading against the p'shat of the Kohelet verse]. This is a very deep secret that one who understands [Kabbalah] will comprehend.
