I disagree that God is not interested in government — or nations. He is God of the individual and of the nations.
My point was that liberals are wrong when they pretend that your and mine Christian duty can be replaced by government programs.
American history has revealed that government pushes Christians and God out of the role of charity and good works when it steals the role, and the Christian participation in that role shrinks the more who adopt the view that “well, government is doing that now and I pay them the taxes, therefore I am fulfilling my Christian role”.
