In its simplest terms, the kingdom of God that Jesus announced and embodied is what life would be like on earth, here and now, if God were king and the rulers of this world were not (Borg, Crossan). Imagine if God ruled the nations, and not Obama, Medvedev, Kim Jong-il, Mugabe, or Mahmoud Ahmadinejad. Every aspect of personal and communal life would experience a radical reversal. The political, economic, and social subversions would be almost endless—peace-making instead of war mongering, liberation not exploitation, sacrifice rather than subjugation, mercy not vengeance, care for the vulnerable instead of privileges for the powerful, generosity instead of greed, humility rather than hubris, embrace rather than exclusion, etc. The ancient Hebrews had a marvelous word for this, shalom, or human well-being.
This Sunday is the last Sunday of the lectionary year, celebrating Christ the King / the Reign of Christ.
