I agree, we are under self-rule. And that means that we have the same obligation to rule the country wisely and attend to the same things that God told various kings to attend to. We must pick our elected officials wisely.
The only wisdom we need in selecting our officials is to be certain we hold them accountable for neglect of duty and for violations of their oath of office. Doesn't take a brain surgeon to be a good administrator or to shuffle papers.
Self-rule is for people who know who the Ruler of self is.
