Bava Basra (the "explanation" of parshas Mishpatim in the Oral Torah) explains in detail the concepts of the mitzvah of tzedekah. Among the fundamental ones is "Great is tzedekah for it brings close the Redemption, as it says, "Thus says the L-rd, keep judgment and do justice [tzedekah], for my salvation is near to come and my righteousness to be revealed."
As a continuation of this, there is also the lesson from the beginning of parshas Terumah (which is read at Mincha on Shabbos): "Make me a Sanctuary and I will dwell among them," beginning with the individual sanctuary within each and every Jew ("within it is not written but within them, within each and everyone"), within his inner heart. [The Sanctuary should also be] in his house and his room, making it a house of Torah, prayer and acts of loving-kindness. This includes in particular joining in building and expanding synagogues and Houses of Study in a manner of "Take for me terumah... gold and silver and copper" (all thirteen (fifteen) things enumerated in the Torah), through which is accelerated and hastened and effected immediately the building of the third Beis HaMikdash in reality, in the simple sense.
This resolution should bring immediately the reward, bringing the Redemption, imminently and immediately in reality, for then the Melave Malka [the meal after Shabbos], "the meal of Dovid, king Moshiach," will be arranged in partnership with the leader of our generation, our righteous Moshiach, at our head, in our holy land, in Yerushalayim the holy city, in the third Beis HaMikdash.
May it be His Will, and this is the most fundamental matter, that the true and complete Redemption through our righteous Moshiach comes into actual reality imminently and immediately... with all the explanations of "MiYaD" (including as well the acronym that encompasses the generations, Moshe, Yisroel (the Baal Shem Tov), Dovid (king Moshiach)).
And specifically to our generation, that the acronym of "MiYaD" alludes to the three periods connected to my sainted father-in-law, the leader of our generation: in the order closest to us, Moshiach (Menachem is his name), Yosef Yitzchak, DovBer (the second name of the fifth Lubavitcher Rebbe). And all the explanations of "mamosh" [really], and above all immediately in the literal meaning of "mamosh", really, really, really.
