Life Under the Sun, Together

We all need relationships with other people.  We want to share the good times with people we love because there is something empty about success when you are by yourself.  We need relationships in hard times so we can lean on one another for help and encouragement.  Relationships and community are the backbones of the human experience and the church.   
What do the writings of a king in the middle east that lived thousands of years ago tell us about how we should function as the church today in the United States?
