Church is not something that you do individually it is something that you do collectively. To be a follower of Christ is not just what you do by yourself it is what you do together with other people. We are what the Bible calls the "family of God." A family is by its very nature inter-dependent. What it means to be a part of a local church is that you're inter-dependent with other people in your church. There are strong reasons why you should come to church regularly.
