What is the point of community?

I'm still reading through "The Relational Way" and the key point that keeps coming up is that the focus of any community group meeting shouldn't be to develop relationships with one another, although that is a crucial part of a community group.  The focus should be on Jesus Christ and having Him at the centre of each get together.  That puts a community group in a whole new light, doesn't it?

Recognizing the value of community

I'm following up from my latest blog post regarding M Scott Boren and his book 'The Relational Way'.
We don't always choose community even if deep down that is what we really want. So, to get people involved in community groups, we need to show them the value of community. What are some ways we can do this?
