One of the disagreements between the North and South during the American Civil War was the status of the Southern states. Southern politicians believed themselves to have completely severed themselves from the Union and proceeded accordingly, establishing their own government. For his part, President Lincoln did not believe that the Constitution granted states the right to secede and so, treated with the Confederacy not as a free-standing political entity but rather as an insurrection. He even went so far as to approve the formation of a “Unionist Government-in-exile” in Virginia and installed “military governors” in several Confederate states to carry on government business as if secession had never occurred. And, of course, when he issued the Emancipation Proclamation, he exercised the authority he believed he had to free slaves throughout the Union, not just in the North. This distinction in the South’s status was no mere political quibbling. Southern ambassadors pressed their case for official state recognition before European governments even as Northern dignitaries urged foreign powers to regard the South as in rebellion.
We might see in this situation an image of the relationship between the Kingdom of God and his enemies. Though God has apparently ceded a certain amount of authority and power to “The Prince of the Power of the Air”, and though the Enemy thought highly enough of his power to offer Christ “all the kingdoms of the world” (Mt. 4:8), the absolute affirmation of Scripture is that “the earth is the Lord’s and the fullness thereof, the world and those who dwell therein” (Ps. 24:1).
Like Lincoln, God does not actually believe that any created reality—human or spiritual—has the authority or right to secede from under his authority. Each exorcism in the ministry of Jesus reclaimed human territory from the enemy that belonged to God.
Continuing the analogy, we might see the church as those “military governors” or as a “government-in-exile”, living in compromised territory but under orders from the true Lord of the land, to carry out his business. In Jesus Christ he has announced an Emancipation Proclamation that applies to all those enslaved in sin throughout his many territories, a proclamation he calls the church to promulgate. This seems to be the imagery at work in Ephesians as Paul exhorts the church to clothe herself in the armor of the Lord and to stand.
The earth is the Lord’s. He has no intention of giving it up. Though the advances and retreats of the Kingdom of God on earth are at times as disconcerting for the faithful as were the defeats and losses of the North during the Civil War, we should take great comfort in the fact that though we reside in rebel territory, no defeat is final, and victory has been secured through Jesus Christ.
