Here's a really good post from Owen Strachan on American history and Church and State.

Sometimes it is as if we evangelicals have applied our sense of individual conversion on a national scale. It is as if we seek to convert America. We cannot do this. We are not a divinely led nation in the sense that Israel was, and thus we do not possess a spiritual identity in the same way that Israel did. Our country is a complex mix of good and bad, right and wrong, and a political theology that leads us to in some way "save" our country on a mass scale is bound to fail. Better for us to push ahead in our kingdom work, to labor with enthusiasm and energy to advance the kingdom and spread the gospel, and work for the application of truth and justice in our society. America is not saved yet--and in fact, she never will be. But there are millions--no, billions--out there who can be saved, and we need to focus our efforts on them.
