The risen one is its head. As surely as the head lives, the body will live. And no destructive power will crumble it. To say this, however, is to say that Jesus Christ himself guarantees that the community of his faithful people will never perish . They are crumbling all the time.
History is littered with the dry bones of dead denominations.
They come and they go every day. We need to put the question much more precisely. Whether or not the fellowship of Christ's people has a future is related to whether or not Jesus himself had a future when he began his public ministry. Whether or not he had a future thereafter depended on his response at that moment. In similar manner whether or not the church has a future depends on our response to the same three temptations that assaulted our Lord.
