At the present, the all-embracing Unity of G-d is not overtly visible; accordingly, the created universe appears to be an independent entity that enjoys a self-sufficient existence. In the future, however, the all-embracing Unit of the Creator will be manifest for all to see: everyone will see how the universe is utterly nullified to the Divine light that flows into it and animates it.(Torah Or, Vaeira)
(L'Chaim)

The Midrash relates that when Moshe noticed that a lamb had run away from the flock and had strayed in the wilderness, he ran after it in order to bring it back. From this we learn how meaningful every Jew is in the eyes of Moshe, even if he is a Jew who has run away from the flock... And since "the first redeemer is also the last redeemer," it is clear that what is true of Moshe is likewise true of Moshiach -- every Jew, wherever he may be, is precious.(The Rebbe, 5743)
(L'Chaim)

At the present time, when the world trembles, when all the world shudders with the birth-pangs of Moshiach... it is the duty of every Jew, man and woman, old and young, to ask himself: What have I done and what am I doing to alleviate the birth-pangs of Moshiach, and to merit the total Redemption which will come through our righteous Moshiach?(Rabbi Yosef Yitzchak Schneersohn, the Previous Rebbe)
(L'Chaim)

Our generation, the generation privileged to usher in the New Dawn of Moshiach, is the reincarnation of the generation of the Exodus. Now, as then, "in the merit of the righteous women" will the Redemption be realized. Now as then, the Jewish women's yearning for Moshiach -- a yearning which runs deeper than that of the men, and inspires and uplifts it -- will form the dominant strain in the melody of Redemption.(The Rebbe)
(L'Chaim)

One should not entertain the notion that the King Moshiach must work miracles and wonders, bring about new phenomena within the world, resurrect the dead, or perform other similar deeds. This is not true.(Maimonides, Laws of Kings, 4:3)
(L'Chaim)

Moshiach signifies the separation of the good from the evil. This is why he will come "only in a generation which is altogether meritorious or altogether sinful," i.e., at a time in which there will be no mixture of good and evil. So as long as Moshiach has not come, there is a mixture of good and evil in all the worlds: there is no good without evil and no evil without good.(Rabbi Shneur Zalman)
(L'Chaim)

The Tzemach Tzedek, Rabbi Menachem Mendel (the third Chabad Rebbe), once said that Moshiach will delight in the company of unscholarly, self-sacrificing Jews. A unique chamber will be set aside for them, and they will be envied by the greatest intellectuals.
(L'Chaim)

Our Sages teach: "Moshiach will come only when the mind is otherwise occupied."

In truth, this is the highest form of expecting Moshiach. We must await Moshiach regardless of our understanding of the benefit we will derive from his coming. We must cast aside all thought of material or spiritual gain, focusing on only one thing: With the coming of Moshiach, the Divine intent of creation -- that G-d will have an abode in this world -- will be fulfilled.
(The Rebbe)

We see in recent years how the verse "Moshe gathered... the Jews" is occurring literally -- the ingathering of the exiles of Jews from all over the world, who are returning to the Holy Land. The current number of Jews ascending to the Land of Israel is incomparably greater than that of previous generations."(From a talk of the Rebbe, Shabbat Vayakhel, 5752-1992)
(L'Chaim)

Unity is the key to G-d's blessings. Thus, in our daily prayers, we say "Bless us our Father, all as one." Chasidic teachings explain that the very fact of being together "all as one," makes us worthy of blessing. And this unity will lead to the ultimate blessing - the coming of the time when G-d will "sound the great shofar," and together "with our youth and with our elders... with our sons and with our daughters," the entire Jewish people will proceed to the Holy Land, to Jerusalem, and to the Third Holy Temple. May this take place in the immediate future.(The Lubavitcher Rebbe, 25 Adar I, 5752 - 1992)
(L'Chaim)

Indeed, the Redemption is very close, for the exile is over, and now we are in the throes of labor. This process is identical to the conclusion of the exile in Egypt, for even after the Jews' slavery had almost ended and their redemption had been announced, their bondage intensified even more -- but not for long, for immediately afterwards they were redeemed.(From The Chofetz Chaim on Awaiting Moshiach)
(L'Chaim)

We must anticipate that G-d will hasten the Redemption by some strategy or other, whether by virtue of the tremendous anguish we have suffered, or by some other means. Perhaps this is the hidden meaning of "in its time, I will hasten it" -- that is, G-d will hasten the period of "in its time" itself.(The Chofetz Chaim)
(L'Chaim)

Just as Israel's redemption in those days was brought about not through our own merit, but through Divine mercy, likewise do we demonstrate through our manner of rejoicing on Purim that we do not rely on our own merits but only on G-d's compassion.(Book of Our Heritage)
(L'Chaim)

The Talmud states, "If Israel were to keep two Sabbaths according to the laws thereof, they would be redeemed immediately" (Shabbat 118b) Why two Sabbaths? Is not one Sabbath enough to show devotion to the day? The Talmud makes reference not to two Sabbath days, but rather to one Sabbath day and the extension of its spirit to the remainder of the week, so that every day becomes enlightened with the sanctity of Shabbat.(Rabbi Aharon Soloveitchik)
(L'Chaim)

The Midrash (Tanchuma, Nitzavim) states: "Israel will not be redeemed until they become one assembly." King David's Psalms end with the words, "All the soul will praise G-d," using the singular for the word "soul." The message is, "If all of us are united as one soul, with one heart, one goal, one dream, then we will eventually bring all of the Jews to say, "Praised is G-d."(Rabbi Moshe Sherer)
(L'Chaim)

Even the great minds who are here must lay aside their intellects and not be ruled by their reason and knowledge, for they are susceptible to being misguided by their intellect to the point that their end may be a bitter one. The essential thing in these times of the footsteps of Moshiach is not to follow intellect and reason, but to fulfill Torah and mitzvot wholeheartedly, with simple faith in the G-d of Israel.(The Rebbe Rashab)
(L'Chaim)

What more can I do to motivate the whole world to cry out and demand the Redemption?... I have done all I can; now you must do whatever you can. May it be G-d's will that there will be one, two, or three among you who will appreciate what needs to be done and how it needs to be done, and may you actually be successful and bring about the complete Redemption, immediately."(The Rebbe, 28 Nisan, 1991)
(L'Chaim)

A verse in Psalm 96 states: "Bring to Hashem, O families of nations," as a reference to the future Redemption, when all the gentile nations will offer gifts to Moshiach. Then Moshiach will tell them: "All I want of you is to bring me the Children of Israel, who are scattered among you -- bring to Hashem, O you nations -- the families of Israel in your midst.(Midrash Shacher Tov)
(L'Chaim)

"The field will exult and everything in it." The Alshich comments that when Adam sinned, G-d cursed the earth which Adam would thereafter have to cultivate for his sustenance. In the future, however, this curse will be nullified and the fields will exult when they return to their original blessed state.
(L'Chaim)

In the future, all the predictions of the prophets will be fulfilled. Their prophecies concerning the Redemption of Israel and the doom of the nations will prove to be faithful and accurate.(Arugat Habosem on Psalm 96)
(L'Chaim)
