In the New Testament, kingdom is used from the Greek word basileai
Refers to "realm" of a king
Westerners think "kingdom speaks of geography
Biblical times emphasized "reign" or "dominion" = wherever the king reigns
The kingdom is within you - Luke 17:21
Seek first His kingdom (not a piece of real estate) - Matthew 6:33
God ultimately reigns over the entire universe but for the moment God does not reign everywhere on earth
Until then we must pray to advance God's kingdom everywhere
