Based on the Dvar Malchus of the Shabbos Parshas Nitzavim, 5751
This week's parsha is called "Atem Nitzavim Hayom". The word "hayom" in the posuk, the Gemara teaches us, refers to Rosh Hashanah, the Day of Judgment. On this day the whole Jewish nation is standing and proven innocent for the New Year.
The Rebbe Melech Hamoshiach Shlita adds that the word nitzavim can also mean kings or rulers. On Rosh Hashanah we crown Hashem as king once again while at the same time we also become kings, deserving of all the blessings, without the least bit of effort, similar to a real king.
We need Moshiach
These are general blessings, and the Rebbe Melech Hamoshiach specifies exactly what he means:
"The main thing and perfection of '...They saved the people...' is to be saved from our current situation and brought into the true and complete redemption."
On Erev Rosh Hashana Chassidim pass by the Rebbe Melech Hamoshiach and hand him a "pan" which contains a request for a good and sweet year. The elderly Chassidim on the same occasion also hand over a pan haklali on behalf of the Chassidim and the entire Jewish nation, requesting a blessing for a good and sweet year in whatever we may need.
In 5252, after the Rebbe received the pan haklali, he started blessing the entire Jewish nation with a very special blessing, including blessings that the year 5752 would be a year of redemption and salvation.
This is what the Rebbe said:
Proven innocent
As we approach the days of judgment of Rosh Hashanah, we are already assured that this year will be inscribed and sealed for a good life, as was paskined in Halacha, which has to take place and as such on Rosh Hashanah the Jewish nation dresses up in their nicest clothing, eats the best food, and is happy, for they are confident that they are close to Hashem and He will paskin in our favor.
Moshiach will come today
We are just before Rosh Hashanah, the birthday of the Tzemach Tzedek. The connection between the Rebbe Tzemach Tzedek and Moshiach is quite clear and obvious. The names Tzemach and Tzedek are two names for the Melech Hamoshiach. In addition, the Rebbe the Tzemach Tzedek is one of our Rebbes, each one in some way is connected to the revelation of Moshiach, because each one of them revealed more Chassidus in the world, as is known the story of the Baal Shem Tov that went up into the chamber of the Moshiach and asked him, "When is the Moshiach coming?" To which the Moshiach responded, "When your wellsprings of Chassidus will be disseminated to the outside."
The Tzemach Tzedek's mazal becomes stronger on his birthday, a day when the Rebbe does everything that is dependent on him and by doing so will succeed to reveal Moshiach's name around the world.
Even those who are still in golus Hashem gave them a good head to learn Torah and a desiring heart to serve Him amidst peace of mind and plenty of gashmiyus for all of their needs as well as those who live in Israel who are close to the Beis Hamikdash and can fulfill those mitzvos that depend on being in Israel – need Moshiach. They also say as part of their prayers, "Because of our sins we were exiled from our land."
With all of the kindness Hashem gave them they still don't have the Beis Hamikdash in addition to the fact that they are unable to fulfill those mitzvos which depend on being in Israel. The mitzvah of yovel can only be performed when the entire Jewish nation is in Israel. As long as some of us are still outside of Israel, those living in Israel will feel their absence.
The geulah has a special connection to Rosh Hashanah, a time when we accept His being king over us, similar to Moshiach will reveal and show the entire world that Hashem is the true king.
It's understood that when the days of judgment of Rosh Hashanah roll around Hashem inscribes and seals the whole Jewish nation for a year in which the Moshiach will be revealed who will redeem and bring us to the true and complete redemption.
Wonders of the geulah
The connection between these days and the geulah becomes even stronger this year, roshei teivos for "This year to be a year of wonders in everything".
May this year bring only good for us, full of wonders, for at any moment the true and complete redemption will take place. We will see wonders any place we look.
The Rebbe Melech Hamoshiach Shlita reveals to us one of the miracles of the geulah. Not only will the geulah take place in the future; it will also be in the past!
More than nineteen hundred years have gone by in this golus, but once the geulah arrives, one big alef will come into the golus, transforming it into geulah! Suddenly we will open up our eyes and realize that the entire history was geulah.
Tachlis
"...Furthermore, and most important, on this Erev Rosh Hashanah, the Tzemach Tzedek's birthday, the Moshiach is revealed..."
Specifically speaking, everyone should certainly use this day for adding more charity and other good things, especially, due to the nature of the day, the Tzemach Tzedek's birthday, for learning his Chassidus and fulfilling his directives.
As already mentioned, the true and complete geulah will come through on this day through Moshiach Tzidkeinu, immediately, mamash.
