Romans 13 (the starting portion)

From our discussion tonight, I feel that it could continue here.

Question from earlier:

1. What is Paul talking about here? What government should we be subservient to? Examples include Moses, Gideon, Daivd, Daniel and Assoc., Jesus, and Paul.
2. What is a "good" government? What is a "bad" government? Is it possible for a totalitarian government, or some other form of "bad" government, to be considered "good"?
   
3. When is government, who is supposed to look out for your well-being, not doing its job?

Discuss.
