Tim Keller (building on Al Wolters) on political idolatry:
Dutch-Canadian philosopher Al Wolters taught that in the biblical view of things, the main problem in life is sin, and the only solution is God and his grace. The alternative to this view is to identify something besides sin as the main problem with the world and something besides God as the main remedy. That demonizes something that is not completely bad, and makes and idol out of something that cannot be the ultimate good.
