1Let every soul be in subjection to the higher authorities, for there is no authority except from God, and those who exist are ordained by God. 2Therefore he who resists the authority withstands the ordinance of God; and those who withstand will receive to themselves judgment. 3For rulers are not a terror to the good work, but to the evil. Do you desire to have no fear of the authority? Do that which is good, and you will have praise from the authority, 4for he is a servant of God to you for good. But if you do that which is evil, be afraid, for he doesn’t bear the sword in vain; for he is a servant of God, an avenger for wrath to him who does evil. 5Therefore you need to be in subjection, not only because of the wrath, but also for conscience’ sake. 6For this reason you also pay taxes, for they are servants of God’s service, continually doing this very thing. 7Therefore give everyone what you owe: if you owe taxes, pay taxes; if customs, then customs; if respect, then respect; if honor, then honor.
8Owe no one anything, except to love one another; for he who loves his neighbor has fulfilled the law. 9For the commandments, “You shall not commit adultery,” “You shall not murder,” “You shall not steal,” “You shall not covet,” and whatever other commandments there are, are all summed up in this saying, namely, “You shall love your neighbor as yourself.” 10Love doesn’t harm a neighbor. Love therefore is the fulfillment of the law.
11Do this, knowing the time, that it is already time for you to awaken out of sleep, for salvation is now nearer to us than when we first believed. 12The night is far gone, and the day is near. Let’s therefore throw off the deeds of darkness, and let’s put on the armor of light. 13Let’s walk properly, as in the day; not in reveling and drunkenness, not in sexual promiscuity and lustful acts, and not in strife and jealousy. 14But put on the Lord Jesus Christ, and make no provision for the flesh, for its lusts.
Word Study: Vain (Gk. εἰκῇ, eike). (Rom 13:4; 1 Cor. 15:2; Gal 3:4; 4:11; Col 2:18) Strong’s 1500
This word pertains to something that is without one of the following: cause, result, purpose or careful thought. It means “vain.” It is only used six times in the NT. In this passage it is difficult to narrow down, but the best option seems to be, “unless you believed to no result.” Paul’s argument functions like a rhetorical question, as the Christian readers (see 1 Cor 1:2) would certainly have rejected the proposition that their faith was to no effect, and that they had believed in vain. To truly believe and do so in vain is impossible. The point is, since the very gospel that Paul preached and by which the readers were saved requires faith in the resurrection of Jesus, how can a believer question the reality of resurrection?
