The Midrash compares that of Rivkah living at her father Besual's house, to a rose among thorns. A rose, on the one hand, belongs to the thorns who defend it. On the other hand, the gardener doesn't care for the thorns at all but tends the roses very carefully. Automatically though, this special care effects and nourishes the thorns as well.
When Rivkah became three years old and became capable of marrying Yitzchok, Avraham immediately felt this spiritually. He only then immediately called his servant Eliezer and told him to go bring Rivkah for Yitzchok. For as long as Rivkah, the rose, was not the suitable age to marry Yitzchok, she belonged to the thorns and Avraham had no power to remove her.
However as soon as she became suitable to leave the thorns and go marry Yitzchok, the thorns possession over her expired and Avraham immediately sent for her.This is why a Neis to make sure that Eliezer would arrive on that same day was necessary - so as not to loose even an extra second of Rivkah being among thorns. This is also why Eliezer told everyone about this Neis: He knew that Lavan and Besuel, knowing that Rivkah was the rose - thanks to whom their family of thorns was sustained, would try to postpone Rivkah's leaving. So Eliezer told them right at the start "I came today". Know that a Neis occurred because every second matters and there is no time to loose. She must come immediately.Maasei Avos - Siman L'bonim.
The story's of our fathers are lessons and directives for us. Just like Rivkah was redeemed from among her thorns, as soon as she was just ready for marriage, in one swift moment, so too will the redemption of the Yidden be hastened, and Hashem will redeem us in one swift moment, not wasting an extra second.

The sicha of Shabbos Parshas Chayei Sara 5745 is an unusual one being that in it the Rebbe speaks in uncharacteristically extremely strong terms regarding those who instead of “koching” in Moshiach rather laugh and mock those who do.
In the sicha the Rebbe speaks about how in our generation the darkness of Golus has intensified to a petrifying degree and the purpose of this is to arouse a Yid to add more to make sure Moshiach comes immediately:
In our generation there exists people who have beards, keep Torah and Mitzvos, and they laugh (!) at the belief that Moshiach is coming very soon.
Which in this can be seen the fulfilment of a clear nevuah of the Rebbe Rashab: In the famous sicha of “Kol HaYotzeh” the Rebbe Rashab writes that before Bias HaMoshiach there will be two generations of scoffers, a generation of people who will scoff at the existence of Hashem and a generation of those who will scoff at the belief in Moshiach. Which this is the strangest phenomena that could exist - frum Yidden who laugh at Moshiach, rachmona litzlan! More than this, they bring reasons of Torah and Yiras Shomayim to defend their opposition, while the truth is that they are really under the influence of the first generation of “scoffers” whodenied the existence of Hashem, as is known the saying that Esav dressed up in a “kapota” and a gartel!
And worst of all is that they educate the young in this spirit. They drive the youth of Klal Yisroel away from Torah and Mitzvos because.
Moshiach is a foundation in Yiddishkeit and one who does not believe in it is, to quote the Rambam, a kofer! Golus and Yidden are opposites, being that we deserve to be together with Hashem in a revealed way. And when this is not the case, it is a terrible thing. Therefore we must cry out to Hashem“l’yeshuoscha kivinu kol hayom” -
