My friend and the rest of her family (six siblings in all) grew up around the corner from us and have all grown into amazing human beings in their own way. My mother and their mother were really close friends, and they used to take us kids to the Anglican church in the next town every Sunday - 8 kids piled in their old station wagon! Thanks to the good side of Facebook, I'm able to keep in touch with every one of them.
They got their compassion from their parents, and really live their faith in a quiet way, making a huge difference to the communities around them. Ruth, featured in this post, has done quite a bit of missionary work in South America with her husband. And I guess the eldest sister doesn't do it in such a quiet way - she's now Bishop of the Montreal Diocese.
