The Importance of Unity in the Church

I want to go back to what John said earlier though about the emphasis on unity and the things that unite a smart church. Why is it that we're so fascinated today by our differences and not that? Go to pastor's conferences, read books, go to missions conferences. Everybody wants to talk about contextualization instead of sharing in common with every other church. What is that instinct inside of us? Any of you? Well, you can't sell what's already there and what's the same.
