I read the quote above in an essay encouraging us to be the active participants in our ward families! Generally, to be the type of person that everyone can always can on! It's a good analogy! And a true one.
I remember Bishop Bostwick in our La Jolla Ward used to tell the ward council that in most wards about a dozen families basically run the ward. And most wards I have lived in that has been the case! There might be a hundred active families but it's still the hard working dozen that do most of the legwork!
