A prominent question in political theory has been to ask, “Who should rule in society”? Who should make the rules that govern us all? Who should legislate? For Plato, it was the philosopher; for Erasmus, the virtuous; for Machiavelli, the powerful; for Lenin, the proletarians with power secured for them by a vanguard party.
But before we can ask "who should rule in a society"?, we must establish why anyone has a right to rule at all. Unless you believe that “might makes right” there must be some ground for human authority. In a word, God.
Founding father, James Otis, "Parliaments are in all cases to declare what is for the good of the whole; but it is not the declaration of Parliament that makes it so: There must be in every instance a higher authority, viz. God." God is the Ground of Legislative Authority As Creator, God is the ground for all rules that bind men. He has made known His will through a moral law that is a reflection of His character. A part of the task of government is to make laws based on God’s moral laws. God’s moral laws come to us in the form of divine commands that bind us. Furthermore, God has given us an intuitive grasp of these commands as a part of the “law written in our hearts…” We often refer to this "law written in our hearts" as "conscience." This “law written in our hearts” is that set of divine commands that we find revealed in the Bible, commands that prohibit such acts as killing and stealing.
Governments are under these divine commands because God has both the power and the right to make rules that bind all men. He has the right in the sense that he is the Creator of all things. As an act of His sovereign right and power, God has delegated to government the authority to impose penalties on the violations of these divine commands. In western democratic nations, we have mostly delegated that function of lawmaking to the legislature.
What's Binding; What's Not Many today, including many Christians, are confused about what aspects of the Bible are binding upon a society and what aspects are not. First, let’s deal with what is binding. God’s moral law is binding; this is not optional. Men are to pass laws that reflect God’s rules given in the form of commandments.
