The month of Nissan is the time most fitting for the Moshiach (Messiah) to come. Since the first geula (redemption when we left Egypt) happened in the month of Nisan we expect this geula to come in the month of Nissan too.
The year after the Shemittah (7th year in the seven-year cycle) is the most fitting time for the Moshiach to come. The Talmud says that the Moshiach is not expected to come on Shabbos so we expect him as soon as Shabbos is over and Shemittah is the Shabbos of years.
Right now we are in the month of Nissan and we are in the year following the Shemittah. This month is the time most fitting of all for the Moshiach to come.
We should be getting our spiritual lives in order now as any minute we are expecting the Redemption. The result of turning toward spiritual goodness now is much greater than it will be after the Moshiach comes. Now there is greater freewill. Choosing good now will bring far greater rewards than it will after the he has come. After the Moshiach comes repentance will be obvious.
Pack your spiritual bags. Things are starting to move quickly.
