13:4 For he is the minister of God to thee for good. {6} But if thou do that which is evil, be afraid; for he beareth not the sword in vain: for he is the minister of God, a {c} revenger to [execute] wrath upon him that doeth evil.
(6) God has armed the magistrate even with an avenging sword.
(c) By whom God avenges the wicked.
13:4 For he is the minister of God to thee for good. The ruler, the guardian of order and the preserver of peace is, as a rule, a blessing.
He beareth not the sword in vain. Not only did the magistrate wear the sword, but one was borne before him in public processions as an emblem of his right to use it in the interests of order and justice.
13:4 The sword - The instrument of capital punishment, which God authorizes him to inflict.
13:1-7 The grace of the gospel teaches us submission and quiet, where pride and the carnal mind only see causes for murmuring and discontent. Whatever the persons in authority over us themselves may be, yet the just power they have, must be submitted to and obeyed. In the general course of human affairs, rulers are not a terror to honest, quiet, and good subjects, but to evil-doers. Such is the power of sin and corruption, that many will be kept back from crimes only by the fear of punishment. Thou hast the benefit of the government, therefore do what thou canst to preserve it, and nothing to disturb it. This directs private persons to behave quietly and peaceably where God has set them, 1Ti 2:1,2. Christians must not use any trick or fraud. All smuggling, dealing in contraband goods, withholding or evading duties, is rebellion against the express command of God. Thus honest neighbours are robbed, who will have to pay the more; and the crimes of smugglers, and others who join with them, are abetted. It is painful that some professors of the gospel should countenance such dishonest practices. The lesson here taught it becomes all Christians to learn and practise, that the godly in the land will always be found the quiet and the peaceable in the land, whatever others are.
