Every day is Labor Day. Jewish tradition expounds the importance of work and those who do it. Even God worked for six days and then rested on Shabbat. The Jewish vision of the messianic era is not an age of idleness, but rather one in which swords become plowshares.
I was recently asked by someone I very much respect to address "the" question. So I started to write the answer in a post... about five times without any luck. The "Why does a 20-something join a Reform Congregation" question.
When we love something, we want to share it – so why not be inspired to bring our Jewish friends into the kehilla kedosha (holy community), embracing them within a wonderful, sacred congregation?
