Romans 13:3-4

MLV(i) 3 For rulers are not a fear to those of the good works, but to those of the evil works. And you do not wish to be afraid of the authority, do you? Do what is the good thing and you will have praise from it; 4 for he is a servant of God to you for what is the good thing. But if you practice what is the evil thing, be afraid; for he is not wearing the sword vainly; for he is a servant of God, an avenger for wrath to the one who is practicing the evil thing.
