Why Do We Need a Religious Community?

Humans are social animals. We need community just as much as we need food and shelter. But why do we need a religious community?  Why do you come here? What are you looking for and are you finding it?  Are you getting what you want or what you need? Is there a difference? Do you need answers to all your questions or maybe just a place where you can ask them?
