Romans 13:4

for he is a minister of God to thee for good. [The law-abiding have no fear of the laws, and have just reason to expect the recognition and consideration which are the rightful dues of honesty and probity. "Commendations by magistrates," says Lange, "in opposition to punishments, were common even in ancient times." "When Paul wrote these things," says Grotius, "rage did not riot against the Christians at Rome." Seneca and Burrhus were still in power, and good men were the objects of governmental protection. "How much to be regretted it is," observes Lard, "that rulers do not more generally recognize the fact here stated by the apostle. Instead of this, however, they appear seldom even to dream that they are placed in office merely as God's servants. Rather, they seem to think that they are placed there solely for their own benefit. The fear of God is often not before their eyes, nor yet the good of the people a tithe as much as their own. Too frequently they serve merely self, with no regard for God, and but little for any one else. Such rulers serve not God, but Satan."] But if thou do that which is evil, be afraid; for he beareth not the sword in vain: for he is a minister of God, an avenger for wrath to him that doeth evil. [As we understand it, the idea which the apostle is seeking to convey is that duties to God and duties to the state are parallel, rather than antagonistic. If the Christian is true to his religion, he need fear neither the state nor God, for God rules, generally speaking, in and through the state, as well as in his providences. If, on the other hand, we do evil, we have reason to fear both God and the state, for the state is merely one of the forms of God's administration. The Romans made much of the sword as symbol of the power of life and death. Her magistrates and officers, holding the power of capital punishment, caused the sword (and the ax) to be borne before them in their public processions. Thus Paul declares that the office-holder is a servant of God to foster the good by praise and commendation, and to suppress the evil as an avenger appointed to inflict wrath--i. e., punishment--upon it.]
