The Previous Lubavitcher Rebbe, Rabbi Yosef Yitzchak Schneersohn, once said:
We are now at the threshold of the redemption. One must be vigilant so that they not fall asleep and squander this time.
When one meets another Jew, they should tell him:
“Listen my brother! Don’t fall asleep before daybreak! Very soon it will be dawn and when the light of day comes, you will regret it…”
In these last moments before the redemption, we must not lose focus. Instead, we should seize the moment so as to ensure that he comes ever quicker.
