If someone tells me that the Messiah is coming on a particular day, I won't believe him. Rather, today, like every other day, I will wait for him, because, "I firmly believe in the coming of the Messiah, and although he may tarry, I daily wait for his coming” (#12 of Rambam’s 13 Principles of Faith).
And if today passes without his coming, I will then know that this was not the day, and I will wait for him tomorrow, and every other day. The Rabbis said, “Come and listen: If someone says, ‘I hereby declare myself a Nazarite on the day that the son of David arrives,’ he is then allowed to drink wine on Shabbat and festivals, and he is forbidden to drink wine on weekdays” (Eruvin 43a-b. Rambam, Hilchot Nezirut 4:11).
If by ten years from now, the Messiah has not yet arrived, I will continue to put on Tefillin, to eat Kosher food and to keep the Shabbat. I will continue to wait for his arrival, and I won't engage in calculations. “Believing in the Messiah means believing and saying that he is going to come, and not thinking that he is going to delay. ‘If he delays, wait for him’ (Chabakuk 2:3). One should not set a time for him to arrive nor seek logical Torah proofs of when that will occur. The Rabbis said, ‘blast the spirit of those who calculate the end’” (Sanhedrin 92b. Rambam’s introduction to Perek Chelek, 12th foundation).
And if in thirty years he has not yet arrived, I will continue to send my children to religious schools, and I will still go to Daven and learn Torah. I will continue to wait, with absolute faith, for “Rabbi Shmuel bar Nachmeni said in the name of Rabbi Yonatan: Blast the bones of those who calculate the end, for they would say: ‘Since that deadline has passed without the Messiah coming, he is not going to come any more.’ Rather, we must wait for him, as it says, ‘If he tarries, wait for him.’ Now one might ask, ‘We are waiting for him, but is G-d not waiting for him?’ It therefore says, ‘And therefore will Hashem wait, that He may be gracious unto you, and therefore will He be exalted, that He may have compassion upon you’ (Yeshayahu 30:18). Now, since we are waiting and He is waiting, what is holding it up? Strict Justice is holding it up. Yet since it is being held up, why should we wait? To receive reward, as it says, ‘Happy are all those who wait for him’ (ibid.)” (Sanhedrin 97b).
And if by eighty years from now the Messiah is not yet here, I will continue to build Eretz Yisrael, the State of Israel, the army of Israel, and I will know that there is much more I must do for all these, and then the Messiah will come.
“A king once got angry at his sheep, and he dismantled the pen and removed the sheep and the shepherd. Some time later he restored the sheep and rebuilt the pen, but he did nothing regarding the shepherd. The shepherd said, ‘The sheep are restored and the pen is rebuilt, but I have not been recalled.’ The same applies in our case. It says, ‘For G-d will save Zion and build the cities of Yehudah, and they shall abide there and have it in possession. The seed also of His servants shall inherit it, and they that love His name shall dwell therein’ (Tehillim 69:36-37). Surely the pen is rebuilt and the flocks are back, but the shepherd (David) has not been recalled. Tehillim therefore continues, ‘[A Psalm] of David, to make a memorial. O G-d, to deliver me’ (70:1).” (Rashi ibid.).
The Messiah comes at the end.
And if in 130 years he has not yet arrived, I will continue to arouse the Jews to move quickly to Israel. And if they say, “We are waiting for the Messiah, and then we will move to Yerushalayim,” I will answer, “You sin and make others sin out of malice, and you do enormous damage, for in the meantime Jews assimilate or are murdered. For ‘it won’t be time for the Messiah’s arrival until the Jews pine for him and say, ‘He’s near!’ or ‘He’s far!’ (Rambam’s Igrot Kiddush Hashem, Mossad Ha-Rav Kook 66-67). We wait for the Messiah every day, so come today!”
And if he has not yet arrived by 230 years from now (the Hebrew year 5999), they will say to me, “Be ready for the Messiah’s arrival, for he will come in the year 6000, as our Sages said, ‘The world shall last for six thousand years, consisting of two thousand years of chaos, two thousand years of Torah and two thousand years of the Messiah’ (Sanhedrin 97a-b), and unfortunately the results were what they were.”
Then I will answer them, ‘I am preparing myself for the Messiah’s arrival now, and not in the year 6000. I recall what happened in the Hebrew date of 5600 (called “Tav Resh”) when rumors spread throughout the Jewish People that the Messiah was coming, based on the verse, “The sound of the dove [Tor – Tav-Vav-Tesh] is heard in our Land” (Shir Ha-Shirim 2:12). At that time, the Rabbi of the Warsaw Jewish Community, Ha-Rav Yaakov Gezundheit, ascended the Bimah on Rosh Hashanah with a Sefer Torah in his hands, and swore that the Messiah would not come that year. Apparently he feared that people would once more go crazy, as they had a few years earlier, when it was prophesied that the Messiah would come. What followed instead were the pogroms of the wicked Bogdan
