The spiritual purification process
This is a well known idea in Chassidus. When the world was created, 288 holy sparks fell and were dispersed around the world. They enliven and bring the world into being. Animals, plant life, fruit, and so on receive their energy from them, reaching impure places as well, and as such even evil people are able to do things and are successful. Our job is to elevate these sparks into the realm of holiness. We do this when we do a good deed or a mitzvah.
For example, tefilin and sifrei Torah, the holiest things in the whole world, are made from animal skin, something that's really lowly. We use the animal skin for a good and holy purpose, thereby elevating the holy sparks in the skin back into the realm of holiness. For this purpose Hashem dispersed us all over the world in order that we should find these holy sparks that fell deep and far into the klipos and elevate them.
The completion of the spiritual purification process
The completion of the spiritual purification process and the elevation of all the holy sparks will bring about the complete geula and then the entire world will serve Hashem with happiness and gladness of heart.
Unfortunately it’s a very long process, more than three thousand years (since Matan Torah) and we're still working on it.
Yaakov is ready for the geula
The connection between our parsha and the geula can be immediately seen at the beginning of the parsha, "...Yaakov sent angels ahead to Eisav his brother..." Yaakov Avinu comes back from Lavan's house where he served Hashem and did his shlichus (directed by Hashem) to make Aram a better and purer place. Now he sends angels to Eisav to inform him that he (Yaakov) has finished his avoda and is now ready to march on to the complete geula!
It's common knowledge that tzadikim refrain from using angels. However, since their shlichus involved telling Eisav about the geula, Yaakov allowed himself to use them. For such an important purpose for which the entire world was created, the angels were willing to forgo their honor and to carry out their shlichus happily.
The problem was that only Yaakov was ready for the geula. Eisav and the rest of the world were involved with their nonsense and therefore the geula was delayed for many years. The job of preparing the entire world for geula was given to Yaakov and his children – the Jews.
The way to completion
Tachlis – what do we have to do now? Our "good deeds and avoda" have illuminated the world over the generations, especially during the last two hundred years since Chassidus was revealed on Yud Tes Kislev. Our Raboseinu Nisieinu have been adding more and more Chassidus over the generations until we reach our generation when the dissemination of Chassidus has reached all corners of the world mamash.
In our times, after our extensive avoda over the years the spiritual purification process has finally finished and as such the world is ready and waiting for Moshiach's arrival. The Rebbe Melech Hamoshiach Shlita has already pointed out that we've already finished our avoda, including "the spiritual purification process"; the buttons are already polished...
The Rebbe Melech Hamoshiach Shlita explains that "...From this it's understood that the continuation of our avoda after this (when Moshiach Tzidkeinu is being delayed for whatever not understood reason) doesn't involve 'the spiritual purification process' (for this has already finished). Our special avoda now is then to reveal his presence in actuality in the world..."
What the Rebbe is saying here that what we had until now and what we will do from now on are two different things. The world opposed g-dliness until now and as a result we had to work hard to fix up the world and make it a better place. Today, the world is already a more perfected and better place and is waiting for the building of the beis hamikdash to occur at any moment. The only thing that has to be done is to bring the lights of Moshiach into it and to start living like we're in the yimos hamoshiach – mamash.
The Rebbe Melech Hamoshiach Shlita adds even more ..."...Nowadays mamash we just have to open up our eyes and see how things really are in actuality; we're sitting together with Hashem ("yisrael vikudsha brich hu kula chad") on a "set table" for the wedding, the meal of the livyasan, the shor habar, and the yayin hamishumar..."
We don't have to wait any more for the geulah. We just have to open up our eyes and see that it's already here!
