I believe it likely that we may be in closer agreement than is apparent. We are pilgrims and exiles certainly in that the satanic world system is utterly foreign and repugnant to us. However, at the same time, we *are* the embassy of Heaven. We are ambassadors of the King (Greek 'Cristos'), the "Blessed and *only* Sovereign" who as our Creator is the only human with a legitimate right to rule us.
All authority in heaven and on earth belongs to Jesus. The government is upon his shoulders, and his kingdom expands endlessly as the nations (Greek 'ethnos' often translated 'Gentiles') hear this good news and exit (exodus) out of worldly kingdoms, flowing into the Kingdom of God (the ecclesia).
