“The fact is that all law is “religious.” All law is based on some ultimate standard of morality and ethics. Every law-system is founded on the ultimate value of that system, and that ultimate value is the god of that system. The source of law for a society is the god of that society. This means that a theocracy is inescapable. All societies are theocracies. The difference is that a society that is not explicitly Christian is a theocracy of a false god. Thus, when God instructed the Israelites about going into the land of Canaan, He warned them not to adopt the law system of the pagans:

I am the LORD your God. You shall not do what is done in the land of Egypt where you lived, nor are you to do what is done in the land of Canaan where I am bringing you; you shall not walk in their statutes. You are to perform My judgments and keep My statutes, to live in accord with them; I am the LORD your God. So you shall keep My statutes and My judgments, by which a man may live if He does them; I am the LORD (Lev. 18:2-5).

“That is the only choice: pagan law or Christian law. God specifically forbids “pluralism.” God is not the least bit interested in sharing world dominion with Satan. God wants us to honor Him individually, in our families, in our churches, in our businesses, in our cultural pursuits of every kind, and in our statutes and judgments. “Righteousness exalts a nation, but sin is a disgrace to any people” (Prov. 14:34). According to humanists, civilizations just “rise” and “fall,” by some naturalistic, evolutionary mechanism. But the Bible says that the key to the history of civilizations is judgment. God evaluates our response to His commands, and He answers back with curse and blessing. If a nation obeys Him, He blesses and prospers it (Deut. 28:1-14); if a nation disobeys Him, He curses and destroys it (Deut. 28:15-68). The history of Israel stands as a warning to all nations: for if God did it to them, He will surely do the same to the rest of us (Jer. 25:29)” (David Chilton, Paradise Restored).
