Darkness is merely the absence of light, and fear is merely the absence of love. If we want to be rid of fear, we cannot fight it but must replace it with love.
As we become purer channels for God's light, we develop an appetite for the sweetness that is possible in this world. A miracle worker is not geared toward fighting the world that is, but toward creating the world that could be.
The reason we don't often confront the larger question of whether or not war is survivable is because of a failure of imagination. We honestly cannot imagine having reached a state in our own evolution in which we do not fight.
We don't need to fight the forces of chaos so much as we need to restore and revitalize the forces of peace.
