4 For the one in authority is God's servant for your good. But if you do wrong, be afraid, for rulers do not bear the sword for no reason. They are God's servants, agents of wrath to bring punishment on the wrongdoer.
4 For he is the minister of God to thee for good. 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 revenger to execute wrath upon him that doeth evil.
English Standard Version
4 for he is God's servant for your good. But if you do wrong, be afraid, for he does not bear the sword in vain. For he is the servant of God, an avenger who carries out God's wrath on the wrongdoer.
4 the government working to your advantage. But if you're breaking the rules right and left, watch out. The police aren't there just to be admired in their uniforms. God also has an interest in keeping order, and he uses them to do it.
New King James Version
4 For he is God's minister to you for good. But if you do evil, be afraid; for he does not bear the sword in vain; for he is God's minister, an avenger to execute wrath on him who practices evil.
New Living Translation
4 The authorities are God's servants, sent for your good. But if you are doing wrong, of course you should be afraid, for they have the power to punish you. They are God's servants, sent for the very purpose of punishing those who do what is wrong.
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, 1 Timothy 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.
