Right away I am struck with the idea of being an ambassador. An ambassador speaks for the leader and not for himself. He or she is a representative of the one who sends him or her. The message of the ambassador, in this text, is one of reconciliation to God. That means, as we know, reconciliation to people.
Community building is the work of the ambassador.
It is an awesome thing to be entrusted with that message. Most of us would rather split off. We are being told by modern students of church growth that we should move toward homogeneity. These homogenized Christian spokespersons mean people who look and are like one another. That's not church building.
