Romans 13 gives instruction regarding authorities.
Many feel that their authorities are either power hungry, incapable of leading, or even ignorant on how to govern people. Though this may be true, these men are in place for a reason, and that reason is ordained by God.
Paul says that God has appointed the governing authorities. There is no authority except from God, and those that exist for us have been instituted by God. Any person who resists or objects to authority has resisted God.
Rulers are not a threat to good conduct, but are against bad conduct. If we do good, we will gain the approval of our authorities. If we do bad, justice is served at their hands, and it is not in vain. These in authority are God's servant for our good, and are an avenger who carries out God's wrath on the wrongdoer.
Therefore, we must be in subjection to authority. Not only to avoid God's wrath, but also for the sake of our own conscience. Paul says these authorities are ministers of God, and this is why we pay them our taxes. Pay all what is owed to them, taxes, revenue, and respect.
Paul said that any person who loves each other has fulfilled the law. All the commandments are summed up in this one simple phrase: "You shall love your neighbor as yourself." Love is the fulfilling of the law.
As Christians, we should ask ourselves: Do we respect our authorities? Do we give them our respect? Are we fulfilling the law with Love?
