When to Disobey the Government

A listener asks the question: "So many of the Christians I speak with today are willing to just roll over, get the shot, hand over their guns...whatever the ‘authorities’ demand on the basis of Romans 13. I know we have to respect authorities as they have been instituted by God but I also believe that we have to resist tyranny. Can you offer any clarification regarding the application of Romans 13 and whether or not this is a blanket statement calling us to submit to any/all authority or am I missing something in terms of context or interpretation?" An extended discussion ensues on this question: When do we disobey? Or should we rather obey?
