You’re right that believers are called saints.
You’re right that believers are called holy ones.
You’re right that hagios includes Christians. I’m not disputing that.
What I’m saying — and what the New Testament itself forces me to say — is that the group that accompanies Christ at His visible return is not determined by the dictionary meaning of hagios, but by the inspired context of each passage.
And in every passage describing the moment of His descent in glory, the “holy ones” are angels, not resurrected believers.
Sorry, but the Bible says that he returns will ALL of them. Maybe you should read more of Isaiah for the details:
The Bible describes the Millennial Kingdom in the book of Isaiah through multiple chapters, most notably Isaiah 2, Isaiah 9, Isaiah 11, Isaiah 32, and Isaiah 65. These passages outline the characteristics of Christ’s future 1,000-year reign on earth following His Second Coming.
Key characteristics of the Millennial Kingdom include:
- Global Peace and Disarmament: Nations will no longer wage war; they will beat their swords into plowshares and spears into pruning hooks (Isaiah 2:4).
- Righteous Rule: Jesus Christ will rule from Jerusalem on the throne of David with justice and righteousness (Isaiah 9:6-7). Princes will also rule in justice (Isaiah 32:1).
- Natural Harmony: The animal kingdom will be restored to peace; predators like wolves and lions will dwell with lambs and calves (Isaiah 11:6-9 and Isaiah 65:25).
- Extended Longevity: Lifespans will be dramatically increased, with death considered premature only for those who do not live to the age of one hundred (Isaiah 65:20).
- Prosperity and Security: People will enjoy the fruit of their own labor without fear or confiscation (Isaiah 65:21-23). Disease and deformity will cease, and the blind will see and the lame will leap (Isaiah 35:5-6).
- Spiritual Knowledge: The earth will be filled with the knowledge of the Lord (Isaiah 11:9).
When the 1,000 years of peace on earth is finished (Revelation 20), Satan will be thrown into the Lake of Fire, all will be judged at the Great White Throne Judgement in order to enter the New Jerusalem/Heaven that comes down from Heaven like Revelation chapter 21 tells us. There will be no need for judges, repopulating, or death in the New Jerusalem/Heaven. That's how we know all of this will take place on earth.
