That verse is a great push for Christians to be more...giving, charitable, which many faithful are. I don't know what this has to do with politics, but we can't save the world's problems, though we can try to help where we can...we got many groups that go to other countries and help build foundations, others work hard and can only give financially. A true Christian will do what he/she can, but there are laws even us Christians must follow to continue great works. Bible verses like these, are there for us to lead better lives, but these works will not save us simply give us peace.
Romans 13:1-5
Let every person be subject to the governing authorities. For there is no authority except from God, and those that exist have been instituted by God. Therefore whoever resists the authorities resists what God has appointed, and those who resist will incur judgment. For rulers are not a terror to good conduct, but to bad. Would you have no fear of the one who is in authority? Then do what is good, and you will receive his approval, 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. Therefore one must be in subjection, not only to avoid God's wrath but also for the sake of conscience.
