Romans 13:3-4

For civil authorities don’t intimidate those who are doing good, but those who are doing evil. So do what is right and you’ll never need to fear those in authority. They will commend you for your good citizenship. Those in authority are God’s servants for the good of society. But if you break the law, you have reason to be alarmed, for they are God’s agents of punishment to bring criminals to justice. Why do you think they carry weapons?
