What will happen to the Gentile empires and what kind of kingdom will God the Son set up?
God the Son will return and smite the Gentile empires that have been on human history for 2,600 years. He will destroy them so they disappear from view, then set up an eternal kingdom, a dominion that shall not pass away or be destroyed. Though interrupted briefly when Satan is released, it continues into eternity.
Les explains that this is God the Son coming before God the Father as He is about to return to earth and smite the Gentile empires that have been on human history for 2,600 years. He is going to come and destroy them, and they are going to disappear from view. Then He sets up His kingdom, a dominion which shall not pass away, and it is eternal. Les notes that it will be interrupted again for a little while when Satan is released, but then comes the new heaven and the new earth, and the kingdom just continues on into eternity. Finishing the verse, His kingdom is that which shall not be destroyed; there He has His rule and reign.
