It saddens me to see so many Christians get wrapped up in politics. We have virtually no sense of history (the early days of what used to be a representative republic were far wilder than the current election cycle) and seem to have lost sight of the two kingdoms in play. Augustine likened them to Two Cities.
The Bible is clear – God created three units of government for this age: the family, the state, and the church. We do not read of any of the apostles nor the Lord trying to overthrow the Roman government, although that is the charge brought against Jesus by the Jewish leaders.
We are not selecting a theologian-in-chief this year. We have not had a solid Christian man in the White House in the past 100 years; all of them have put politics above Truth for the most part. We play into the hands of the world when we try make this country into the mold we imagine for it. But no matter how much we desire a secure temporal future under a God-fearing government, that is not where our security lies.
The best thing for this country would be political leaders who cling to the Constitution, just as the best thing for our local churches are men who cling to the Scripture.
The political machinery in D.C. all works together to consolidate power at the national level (the Whig Party lives in the policies of both current parties). No matter if your favorite President was Woodrow Wilson, Ronald Reagan, GW Bush, or Bill Clinton (all professing Christians) – none of those men were able to put this country on the foundation of Scripture. That is not the job of the President.
If your view is that you must vote for a truly godly person as President, how is your position different from the Jews who clamored for a king like the pagan nations had, discontent with having YHWH as their King?
A President who will work against the status-quo and try to push the national government back to it charter document will do this country good, no matter what you or I think of his theology.
