The “Two kingdoms” idea is not a categorical and simplistic default position for a Christian to use as a justification to espouse blind submission to government authority. A ruthless leader may portray an unjust war as in the ‘national interest,’ and compel Christian citizens to participate on the basis of nationalism, even though the conflict is immoral and motivated by greed and power. The war itself may be a war of conquest or colonization, and even alliances and treaties do not always justify the participation of Christians. So then, what loyalty is owed to the earthly kingdom? Where does faithfulness to God and His word fit into the scenario? Following the Lord means discerning the difference and acting accordingly.
