A lot of times we, as a church body, forget that the importance of church is to bring others in to tell them of Jesus Christ.
Church is much more than a gathering place of friends.
I've been in many churches where I just didn't feel accepted. Needless to say, I wasn't anxious to go back. Sometimes we turn our churches into small cliques of people with the same interests. Upon doing that, we tend to shut out people who are searching for Jesus Christ. I think that often times a visitor leaves a church service with that type of feeling.
