When we do miracles, meaning to do more than what we're use to, Hashem will also perform the big miracle for us - the true and complete redemption. Then we will be able to offer the Korban Pesach properly as free people.
The Rebbe Melech Hamoshiach emphasizes:
"Furthermore, and most important, the true and complete redemption by Moshiach Tzidkeinu will come immediately on Shabbos Parshas Viyikra, rosh chodesh Nisan, 5751, may it be a year that I (Hashem) will show them wonders".
Shabbos is connected to the redemption, for it expresses what Shabbos is all about. Parshas vayikra speaks about the mishkan which is connected to the redemption, a time when we will have the third Beis Hamikdash.
Rosh Chodesh Nisan is a month of redemption, and the year 5751 is connected to the posuk that refers to Moshiach "...And he will uplift his kingdom..." We see clearly that this day (Rosh Chodesh Nisan) is especially connected to the complete redemption.
Before Pesach comes around, we will all be in the holy city of Jerusalem where we will offer the Korban Pesach and will happily thank Hashem for the redemption.
