There are probably many Christian approaches to politics. From the political involvement of most Christians, I would assume that their strategy is identical to non-Christian groups. Christians tend to focus on an issue or candidate, evaluate that person with their value system, accumulate a power base in reaction, and do what they can for or against. That is how politics works, and that seems to be how Christian politics works. Perhaps there is a difference afterward in the way the country runs; perhaps not. But is there a difference afterward in the way people view Christ? Perhaps Christians gain more respect and power after a political battle; perhaps not. But is their reflection of God one that becomes Him, and is their witness one that pleases Him?
