Pekudei teaches that the Mishkan, the two Batei Mikdash, and the future Beis HaMikdash are all one continuing sanctuary for Hashem. The Rebbe explains that even in times of destruction, the Mikdash is only a temporary collateral, and our task is to make the shul, the home, and the world into a dwelling place for Hashem.
