This is a brief treatment on what happens when 'the powers' fall. For Wink 'the powers' are completely demythologized and simply stand for social structures and political entities. In this book, Wink means oppressive regimes.
Wink's purpose is articulate the appropriate response in the wake of the fall of oppressive regimes. Wink argues that the kingdom of God (reign of God)articulates a whole new way of being in the world characterized by non-domination, forgiveness and reconciliation. He spends sometimes painting a picture of what that means by recounting stories of reconciliation and examples of international situations where reconciliation is needed (mid 1990's was publication date, but these could be easily updated). Wink closes the book with a passionate plea for democracy as the ultimate expression of non-domination.
I think this book has some interesting insights, and certainly believe the vision of Jesus and the Kingdom of God should have an effect on our politics. Yet, Wink's analysis is rather shallow in this treatment (more suggestive than substantive). His conjecture that democracy is the form of government which most fully embodies the values of the kingdom of God, is suspect. It may be true that non-domination is characteristic of the reign of God but democracies are not always hospitable to voices on the margins. Totalitarianism is wrong, but so is mob-rule. Certainly Wink would allow as much, but I wonder if he puts too much hope in democracy. Democracy is not the hope for the world. Jesus is. Democracy is a better alternative than dictatorship, but not the ultimate expression of all that the reign of God means.
