This brand of Christianity comes from the idea that it is up to the true followers of Jesus to pre-establish God's kingdom upon the earth. This is accomplished through human might and power leading to a form of theocracy in which the Christian God will rule their nation through divinely elected Christian men and women. This is the very same ideology that permeated 1st century Judaism as they waited in eager anticipation for their prophesied Messiah to deliver them from the great oppressor and establish a great Jewish utopia. When Jesus the true Messiah came to Jerusalem not on a majestic steed with pomp and circumstance, but instead on an obscure colt with only a few ragtag disciples trailing behind, the Jews were most assuredly disappointed. Only later did they witness this Jewish King being flogged and ultimately executed upon the Roman instrument of death known as the crux, or cross. Little did they know that the Kingdom of God was indeed in their midst. But, the way in which Jesus became King and Lord over all was not by might, power, and politics, but through the sheer love, grace, peace, and sacrifice toward others. Not a single sword was raised, nor a single political action signed; His kingdom was ushered in by individuals willing to love and serve others at the expense of sacrificing their own lives just like their King.
How many American Christians today envision their utopia in much the same way 1st century Jews did? We Christians seek to establish a Christian kingdom through our elected officials, political action committees, and socio-political protests, turning a blind eye to the King who sits atop a colt in our midst. But, it is only when our society witnesses the true kingdom power of Christ in the form of holistic, incarnational ministry, and peaceful evangelism will our society truly be transformed. When we Christians seek to love and serve all people from all walks of life, even those who we may deem our enemy, will the true power of Christ radiate like a beacon of light on a hill capturing the souls of those who need Him most. Until then, the American church has a lot of introspective soul-searching and idol-smashing to do... namely the idolatry of the American political and government system found within the confines of the American church.
Politics and government in of themselves are not evil; in fact they are established by God himself (Romans 13:1). But, when they become the vehicle, or the alternative, for which the Christian church should be otherwise interacting with, engaging, and transforming our society, then it becomes evil. For then it merely becomes yet another government imposed policy of Lord Caesar and not the humble and loving servanthood of Lord Jesus. And, we know lives are not changed by forced policies, but only by the voluntary freedom of the soul. After all, the reason why the American government is so large today, is not because of some liberal socio-political agenda or conspiracy, but because we the church have delegated Jesus' command to "love thy neighbor" to Uncle Sam. It’s time we the church give Uncle Sam the boot and change our society not through the might of Caesar, but through the power-under, servanthood, and humility of Christ. Not through the institutionalized civic religiosity of Constantine, but through the down and dirty, in-the-trenches, relational aspect of kingdom Christianity.
