What role will Israel have compared to the other nations when Christ is King?
When Christ reigns over the kingdom coming down from heaven, Israel will be the head of the nations. All other nations will also be present, but they will occupy a lesser role than Israel, the covenant people. This fulfills the promise of one nation under one king.
Les explains that when this kingdom comes down from heaven over which Christ is going to be the King, Israel is going to be the head of the nations. All the other nations are going to be there, but in a lesser role than the covenant people. He connects this to the promise that they will be one nation, and one king shall be king to them all; they shall be no more two nations, neither shall they be divided. He also notes that this will happen at the Second Coming, when His feet shall stand upon the Mount of Olives.
