By now, as we begin to prepare for Succot, it should become obvious how much the Beit Hamikdash is missing in our lives. As beautiful as the holidays are in Eretz Yisrael, they are only a taste of what it was when the Temple was standing.
The Talmud in Brachot points out that not only do the righteous cry out every night for the Temple that was destroyed, but Hashem cries as well.
"The night consists of three watches, and at each and every watch the Holy one Blessed is He, sits and roars like a lion, and says, 'Woe to the children because of whose sins I burned My Sanctuary-and exiled them among the nations of the world."
Perhaps if we long for the rebuilding of the Temple as the righteous and Hashem Himself does, it will be built speedily.
