We must seek the z’chusim (merits) of the Jewish people. The Gemara (Shabbos 63a) states that when a tzadik finds a z’chus on the Jewish people, even if Hashem has decreed a decree, Hashem will annul that decree.
In the days of Gideon, the Jewish people were in distress, and Hashem was seeking someone who would find merit in them. When He found Gideon to be meritorious, because he found merit in them, immediately G-d appeared to him, and said (Shoftim 6:14): Go with this power, with the power of the merit you have found in my children.
"Said the Holy One, Blessed be He, it is within your capacity to find a defense for Israel. In your merit they shall be redeemed. "
Similarly, the Gedolei Yisroel (Jewish leaders) throughout all generations endeavored to find merits on the Jewish people, even when they were on a very low status. Because when they are in such a low state, every mitzvah they perform is very special and precious. This is especially so in finding merit regarding the Geulah: The merit which will hasten the Redemption is the following: Even in the time of the Talmud it has been said (Sanhedrin 97b) that "all pre-determined dates have passed."
Certainly nowadays, that we have endured a lengthy and difficult golus, which has exceeded more than 1,900 years - and he [Moshiach] has still not arrived - ... And as for Teshuvah (repentance) which is a prerequisite for Redemption – the Jewish people have already done Teshuvah. Indeed, there is no Jewish person in whose mind has not entered a thought of Teshuvah, (not just once, but) several times in the course of his lifetime.
This [thought of Teshuvah] can transform momentarily a completely wicked person into a perfectly righteous individual (as the gemara states in Kedushin 49b); It follows, that with the greatest certainty our righteous Moshiach must arrive here and now, immediately, actually in the most literal sense.
This limud Z’chus (finding merit) in and of itself should suffice to bring about the Redemption. Moreover, in addition to the finding of merit, there is also a definitive ruling issued by many Rabbonim and halachic authorities. And, since Torah "is not in heaven," this ruling issued by the earthly Beth-din, "obligates," so to speak, and affords a unique privilege to, the heavenly courts. “Vechein yakum” - And so it will stand!
