A great definition of community

In 4 days I am speaking at a pastors' conference on 'Building Community by serving each other'.  I haven't got it all together yet, but I am totally using this Wendell Berry quote:
“A community is the mental and spiritual condition of knowing that the place is shared, and that the people who share the place define and limit the possibilities of each other's lives. It is the knowledge that people have of each other, their concern for each other, their trust in each other, the freedom with which they come and go among themselves.”
