"So many Mahlokot in Kelal Yisrael, how can Mashiah come in such an environment?"
This refrain and others like it can be heard in shul social halls and read at least 100 times a month on Internet posts, tweets, comments, etc. And it truly is upsetting. But is it accurate?
Must Mashiah come only in a state of Ahdut? I know, I know, I have countless posts on the importance of Ahdut before Mashiah. But, is it Me'akeiv? Is it impossible for Mashiah to come without Ahdut? The sources seem to say no.
First of all, we know that Mashiah can come in a Dor Shekulo Hayav. Of course, this is not an ideal situation, but one of the 2 possibilities, and the scenario that seems - with our limited eyes - to be the one we're headed for.
Secondly, we know that Mashiah is supposed to come in a state of desperation. It could mean financial desperation, military desperation, or social desperation. When every subgroup is on-edge due to attacks from its neighboring subgroup, this is a case of social desperation.
Finally, we know that Mashiah is supposed to come with היסח הדעת - while our minds are off the topic. Maybe the aforementioned refrain has contributed to this היסח הדעת that has caused us to give up hope on Mashiah coming any time soon.
We see that Mashiah could come in any situation. Of course, this does not mean that we should now misbehave ח"ו to bring the Geula. (Just the opposite - we need to do our part and Hashem will do His. And both Ribbi Yehoshua and Ribbi Eliezer agree that Teshuva must come one way or another.) It just means that we should not automatically assume that if the groundhog sees its shadow, we're in for many more days of winter. עת הזמיר הגיע - spring could come much earlier than anyone expects in our current situation.
The second Beit Hamikdash was destroyed in the year 68CE (according to our tradition, כמנין חיים). This means that we now have been missing our Beit Hamikdash for 1945 years. (Many prayer books instruct us to insert the number of years since the Hurban in the Tish'a Be'av liturgy.) 1945 is the gematria of the following verse which describes Shelomo Hamelech blessing Israel after the completion of the Beit Hamikdash:
May we merit to limiting the Hurban to a long-enough 1945 years and seeing only blessing and the promised consolation, speedily in our days. Amen.
