Will the kingdom be interrupted after it is set up?
Yes. After the kingdom is established as an eternal dominion that shall not pass away, it will be interrupted again for a little while when Satan is released. After that, the new heaven and new earth come, and the kingdom continues on into eternity without being destroyed.
Les explains that the kingdom is eternal, a dominion that shall not pass away and shall not be destroyed. However, he notes it will be interrupted again when Satan is released for a little while. Following that interruption, the new heaven and new earth appear, and the kingdom just continues on into eternity.
