The gemara tells us that when Moshiach comes, the Batei Knaysiyos and Batei Midrashos will be uprooted and relocated to Eretz Yisrael. The Satmar Rebbe, author of the Divrei Yoel, is bothered by what the purpose of this miracle was. Miracles aren’t done if it is unnecessary.
He explains that in the future the yetzer hara will be slaughtered. Since there won’t be any yetzer hara, Avodas Hashem will be with ease. Now, we know the principle of l’fum tzaaara agra, the reward is in proportion to the effort.
Consequently, in the time of Beis Hamikdash, we will long for the Avoda of galus when it was difficult as the Avoda we did in galus is more significant to us. As a result, Hashem will bring the shuls of chutz laaretz to Eretz Yisrael so that we can still connect and have that taste in the ultimate future. So even though when Moshiach comes, we will have the Avoda of the Beis Hamikdash but the Avoda of galus is on a higher plane since it was more difficult.
