It is written in the Gemara Sanhedrin that Mashiach is called "Bar Nafli."
What is the meaning of "Bar Nafli"?
The meaning is ben nefilot [a son of repeated falls], one who falls.
That's what they call Mashiach.
The commentators ask: Why do the call him Ben Nefilot [a son of repeated falls]? What kind of a name are they giving Mashiach?
One of the great mekubalim wrote a book called Pitchei Shaarim. And there he explains that Mashiach is called Bar Nafli because he constantly wants to bring the Redemption, and The Holy One Blessed Be He casts him down and says to him:
"The time has not yet come. There is still a Jew who has not yet merited."
The Holy One Blessed Be He sent Mashiach to the entrance of Rome. And there, Mashich undergoes very great falls. He constantly wants to bring the Redemption, but The Holy One Blessed Be He doesn't let him.
The Holy One Blessed Be He is waiting for every single Jew to return to Him out of love in order to fulfill [Shmuel II 14:14] "he that is banished may not be banished from Him."
The tikkun is to transform the animal soul to a Godly soul via the powers of emotion emanating from the human spirit.
Note #2:The Hebrew word used above is mapil (מפיל). It literally means "cause to fall" and is often translated as "casts down" or "pushes down" or "knocks down."
A lot of people feel rejected by God.
A lot of people feel like no matter how hard they try and no matter how hard they want things that are actually GOOD to want, God not only blocks them; He actively pushes them back or knocks them off their feet.
Yet the Gemara clearly tells us that this forced falling-down is a classic aspect of Mashiach!
Mashiach is going through the exact same experience as you.
I don't know all the reasons why or the deep mystical significance of the whole dynamic (other than that mentioned above: Hashem is braking the Geula process out of His Great Love for each individual Jew, especially the ones who aren't anywhere near teshuvah yet).
But it makes me wonder whether these same people who are feeling so rejected and knocked completely off balance are davka the people with the biggest, brightest spark of Mashiach within them.
After all, another Gemara also tells us that this is an upside-down world:
Those who look great and prominent in This World are quite small in the Next.
And those who seem insignificant and small here are actually quite great and prominent in the Next World.
A candle flame isn't particularly bright or powerful. But in a corner of pure darkness, its light is significant.
Yet from a distance, its light is unnoticeable.
You can only perceive a candle's light when standing nearby.
