I second that. Preach the faith, not the politics. G-d knows, people today have too little of the former and far too much of the latter.
While many of the mainline protestant churches today are apostate liberals lacing in genuine faith, that does not neccessitate that true Christians should not be active in the political process. God, throughout Scripture exhorts His people to govern His creation well with a strong emphasis on justice for all. Sound familiar?
I hear that!
