The Rebbe said:<ref>Based on [http://www.sichosinenglish.org/cgi-bin/calendar?holiday=pesach21 Likutei Sichot vol.7 pp. 212-3]</ref>
:The Lubavitcher Rebbe explains this point as follows: Every Jew has to strive not only for his or her own perfection, but for the perfection of the entire world. This means that we have the goal that all humanity should respect G-d's Will, as expressed in the Seven Noahide Laws.
:The fact that the Egyptian first-born were trying to persuade their parents and Pharaoh to obey G-d's Will and let the Jewish people free was an important step forward in this wider task. This was and is still today an ample cause for celebration, remembering the Sabbath when it took place as the "Great Sabbath".
