Bear with one another in love
This game relates to how King of Peace becomes not just a church, but a real community. How well do you know the people with whom you attend church? It is impossible for us to accomplish our goal of bearing one anothers burdens and sharing one anothers joys unless you share of yourself. The congregation cannot support you in your times of need and rejoice with you in your time of joy unless we know of your needs and joys.
It begins with seeing, really seeing, the people with whom you go to church. Then just follow your natural curiosity and when you say hello, ask questions. "Where do your kids go to school?" or whatever question seems appropriate. It is easy to keep sharing worship with one another without getting to know each other. But it is also surprisingly easy to meet new people and get to know their joys and sorrows, challenges and frustrations. Then you'll have a basis for building the community you need, and the community that King of Peace is called by God to become.
You can read about the Bible's view of Christian community by reading the one anothers here online. Also related, but working on a different part of the question of what a Christian community is for, is today's sermon Why bother with Church?
