What is the Purpose of Government?

My brother missed church last Sunday, and so went online to find a good sermon to watch later that week, and found this one. It is very good and about 15 minutes long, and is about what the Bible teaches us about government in our society. The sermon makes a great point about how public schools teach students that the Bible says nothing about government, but this is incorrect. I agree, and discussions on government and politics in my class sometimes stray dangerously (for my career) close to religion at times.
