God, like all revolutionaries, desires the overturning, the radical alteration of the whole society—for in this the revolutionaries are right: what is at stake is the whole world, and the change must be radical, for the misery of the world cries to heaven and it begins deep within the human heart. But how can anyone change the world and society at its roots without taking away freedom?
It can only be that God begins in a small way, at one single place in the world. There must be a place, visible, tangible, where the salvation of the world can begin: that is, where the world becomes what it is supposed to be according to God’s plan. Beginning at that place, the new thing can spread abroad, but not through persuasion, not through indoctrination, not through violence. Everyone must have an opportunity to come and see. All must have the chance to behold and test this new thing. Then, if they want to, they can allow themselves to be drawn into the history of salvation that God is creating. Only in that way can their freedom be preserved. What drives them to the new thing cannot be force, not even moral pressure, but only the fascination of a world that is changed.
Clearly this change in the world must begin in human beings, but not at all by their seeking through heroic effort to make themselves the locus of the new, altered world; rather it begins when they listen to God, open themselves to God, and allow God to act.
