As Shabbat inches closer each week, my kids usually don't ask what I'm making for dinner. Instead, they ask, "Who's coming for dinner?" This is because they realize that even if I were to serve something as exotic as Thai or Moroccan food (unlikely), it's our guests who really spice up our Shabbat and holiday tables. It's kind of like diner's roulette: Often, we meet our guests for the very first time when they walk through our front door for the meal.
As part of an Aish HaTorah community that emphasizes kiruv (outreach to unaffiliated Jews), we enjoy hosting guests who are new to Judaism.
