A Tale of Two Kingdoms
In our Christian circles in the United States today, we can 
discern a “Christendom” view, where some imagine America to be a 
Christian nation invested with a divine commission to bring freedom to 
the ends of the earth. Of course, Christians have an obligation both to 
proclaim the heavenly and everlasting freedom of the Gospel and the 
earthly and temporal freedom from injustice. But they are different. 
When we confuse them, we take the kingdom into our own hands, 
transforming it from a kingdom of grace into a kingdom of glory 
and power.
 
We also recognize an opposite view, more characteristic of the Anabaptist perspective, as evangelist D. L.
 Moody asserted: “I look upon this world as a wrecked vessel. God has 
given me a lifeboat and said to me, ‘Moody, save all you can.’” In this 
view, improving the lot of our neighbors in the world is like polishing 
the brass on a sinking ship. Christians are often encouraged to focus 
almost exclusively on personal salvation (their own as well as that of 
others), unsure of the value of their secular vocations. 
 
But we need not choose between these two kingdoms. Citizens of 
both, we carry out our vocations in the church and the world in distinct
 ways through distinct means. We need not “Christianize” culture in 
order to appreciate it and participate in it with the gifts that God has
 given us as well as our non-Christian neighbors. Though called to be 
faithful in our callings until Christ returns, with Abraham, we are 
“looking forward to the city that has foundations, whose architect and 
builder is God” (Heb 11:10, hcsb).  --Michael Horton
