Bruce Ashford and Chris Pappalardo in their book, One Nation Under God: A Christian Hope for American Politics:
So, the political realm has everything to do with our relationships to other people. In the aftermath of the fall, the political realm remains structurally good but has been corrupted directionally. In other words, God structured the world in such a way that we would have politics and public life, and the fact of its existence is good. But because of the depravity of the human heart, politics and public life are always to some extent directed toward idols rather than toward God.
The problem runs deep, deeper than most political analysts even conceive. But the problem is never politics, per se. Liberals aren't the problem. Conservatives aren't the problem. Politicians aren't the problem. We are. We all are—because we all have the entrenched tendency to twist God's created order into idolatry. Pointed toward Christ, anything in creation becomes a blessing. Pointed away from him, the greatest blessing becomes a curse.
