James Jordan says:
The gospel is the announcement that Jesus is now king of the entire world, and that all nations are to be discipled. Israel was the model discipled nation, and now all nations are to be discipled. Israel’s history relates typologically to all the world now, as we are put into the olive tree. Everything God told Israel, including the Law, is typologically normative for all the world, for all nations. I call this “Biblical theocracy.”
The gospel is not theology or ideas. It is not experiences. It it not even the church considered merely as some kind of annabaptist worshiping community in the midst of a world that will never be changed. The gospel is a new creation, a new world. It is Christendom. It is theocracy. This is not “theonomy” as Bahnsen defined it, but it is close enough that it looks like it to many people. And the practical implications of Biblical Theocracy are often quit similar to “theonomy” as regards the discipleship of nations, because typological application is still application. And just as the early church directly challenged Caesar’s purported lordship, there is a need today for the prophetic people of God to directly challenge modern ideas of law and democracy and insist on the crown rights of King Jesus.
