As we approach the time when Jesus will set up His Millennial Kingdom on earth from a renewed Jerusalem. It is helpful to look at why and how God initially set up His nation Israel. God initially set up nations at the Tower of Babel when He confused the languages. Nations are God’s idea and they were made for His purposes. Even before the Israelites entered the Propmise Land, Moses told the people prophetically all that would happen to them including their being cast out of the land and being dispersed all over the world but God would gather them back to the land and eventually their promised Messiah will rule the nations from new Jerusalem.
