How will the millennial kingdom end, and what will the new heaven and earth be like?
The millennial kingdom ends through the providential acts of a sovereign God, and everything must pass through a great turmoil. When the new earth and new heaven appear, they will be characterized by the same set of circumstances that existed during the thousand-year rule and reign.
Les teaches that Revelation places a time element on the kingdom: it lasts a thousand years, which is why it is called the millennium. That thousand years of rule and reign will end by the providential acts of a sovereign God, and everything will have to go through a great turmoil. When the new earth and the new heaven come on the scene, Les explains that it will be the same set of circumstances that were seen in that thousand-year kingdom. This connects with the kingdom God sets up in the days of those kings, the kingdom that shall never be destroyed.
