Romans 13 asks for submission to earthly government as ordained by God on the basis that the principles of human government are necessary for the suppression of evil and allowing that which is good. The immediate reason for Paul writing this is because to not submit may bring the wrath of government and also be against Christian conscience. This passage does not call for submission to Nero. Rather, it portrays a government with basic principles that Nero did and would violate–which led to his being hunted down by his own citizens. Some government entities within the Roman Empire were still functioning for the basic good, and so could be submitted to. Nothing Paul says here, however, prohibits nonviolent civil disobedience should the Holy Spirit of God instruct his servants to do so.
