This is a fantastic article from Julian Linnell, director of Anglican Frontier Missions. Again and again, I hear people ask what connection is there between missions and the local church, or more accurately say that they and their parish are too busy with more important things to be able to get involved with the edges of the world. Julian has a different answer.
Pete Wait (The Rev. Dr.) has suggested the image of a water sprinkler, the kind that waters all the grass in the lawn. It would be rather foolish to simply turn on the hose and hope that the water will spread across the lawn; it is much more effective to hook the hose up to a sprinker system that spreads the water to the edges of the lawn. Simply put, if the water catches the edges, then you can be confident that everything in the middle of the lawn will also be watered. Churches that focus on local ministry hoping to someday spread out and tackle ministry at a distance, rarely go global and even more rarely reach out to that quarter of the world’s population who have no access to the Gospel. On the other hand, those that aim to get involved with the ends of the earth right from the start, almost always also get involved with other missions and local outreach: the sprinkler covers the whole lawn. God has said that he loves the world, the whole world, and that we are called to be witnesses of Jesus Christ in all parts of the world, in Jerusalem, in Judea and Samaria, and to the ends of the earth. (John 3:16; Acts 1:8)
