Christians are prohibited from ever despairing of the peace possible in the world. We know that as God’s creatures we are not naturally violent nor are our institutions unavoidably violent. As God’s people we have been created for peace. Rather, what we must do is to help the world find the habits of peace whose absence so often makes violence seem like the only alternative. Peacemaking as a virtue is an act of imagination built on long habits of the resolution of differences. The great problem in the world is that our imagination has been stilled, since it has not made a practice of confronting wrongs so that violence might be avoided. In truth, we must say that the church has too often failed the world by its failure to witness in our own life the kind of conflict necessary to be a community of peace. Without an example of a peacemaking community, the world has no alternative but to use violence as the means to settle disputes.
