Romans 13:3-4

For [civil] authorities are not a source of fear for [people of] good behavior, but for [those who do] evil. Do you want to be unafraid of authority? Do what is good and you will receive approval and commendation. For he is God’s servant to you for good. But if you do wrong, [you should] be afraid; for he does not carry the [executioner’s] sword for nothing. He is God’s servant, an avenger who brings punishment on the wrongdoer.
