A central question for Judeo-Christian faithful is "Are we living in the age of antichristism or kingdom influence?" Can we salt and light entire cities and civilizations, as Martin Luther King Jr. hoped, or with D. L. Moody should we simply save as many as we can from our rapidly sinking planet? Over the years Christians have wrestled with the question and reached different conclusions. Augustine's and Oliver O'Donovan's answer to the question birthed The City of God and The Desire of Nations. Miguez Bonino's and Grace Ji-Sun Kim's Marxist-influenced liberationist answers produced Toward a Christian Political Ethics and the post-truth Intersectional Theology. Former socialist Michael Novak's plea was to revive The [True] Spirit of Democratic Capitalism. Jonathan Cahn and Frank Peretti, by contrast, predicted that we have entered the age of This Present Darkness amidst The Return of the Gods. Peretti's and Cahn's wildly popular future-visions built upon Hal Lindsey's dated assurance and false prediction that true believers would be raptured in the last decade of The Terminal Generation--1980s! Douglas Matthews offers a new route through the maze and discerningly answers this perennial question by boldly offering a "Third City" future-vision option for effective kingdom influence amidst accelerating global antichristism.
