Dear Kehilá:
One of the issues discussed in this section of the Torah is the "Second Passover".
This is the story of a group of people who, when God commanded them to offer the Passover sacrifice, were in a state of ritual impurity that prevented them from participating. Upon being "left out," they cried out, "Why are we being discriminated against?".
In response to the outcry, God gave the "Second Passover," an occasion in which those people "left out" on the first Passover could fulfill the mitzvah (Divine precept) of Passover like everyone else.
The Chabad Rebbeim draw a wonderful practical lesson from this seemingly insignificant story: "There are no lost causes." In other words, regardless of one's level of knowledge, how far away one is, or how badly one has behaved, in Judaism there is always another chance.
The only "condition," so to speak, to be worthy of the opportunity is to cry out, from the depths of your heart, "I don't want to be left out!"
