Before responding to your points I must say, I do not know why Ezekiel has a vision of a temple with sacrifice re-instated. I am merely answering her question as if the doctrine of the millennium were correct. I have read commentary saying that Ezekiel's temple was the plan for Ezra and Zerubbabel to build after release from Babylon. But the measurements of Ezekiel's temple are massive and what was built pale in comparison. I've been to Israel and have seen the model for Ezekiel's temple made by the Temple Institute in Jerusalem. It is a skyscraper, not the simple 3 story structure of Solomon. They are serious about building Ezekiel's temple if they get the chance. We could say it is just their zealous desire to restore the temple, but why did God give Ezekiel such detailed and specific instructions?
Now, and forevermore, Human beings are either "in Adam", Just as before the law was given to Moses, and Condemned to Death whether they sin or not, or they are "in Christ" saved even though they are sinners.
Individual Sins are no longer the measuring Stick God uses to determine ones salvation status, in fact, ONLY sinners Get saved.
This is correct. Sin and death are in Adam, and before the Mosaic law all still died even though there was no law and sin was not imputed to them. But that is not the point. The point is awareness of sin. Without the law awareness of sin was mitigated. The conscience and heart had the knowledge of right and wrong, but hardness of heart is the fallen condition. The law was given to increase awareness of sin. This is why I speculate that the temple and sacrifice would be reinstated for those born during that time who remained in Adam to make them aware of their sin. At the end of that thousand years, those who realized their sin and need for salvation, would be like the Old Testament saints in Heb 11.
Heb 11:39 And these all, having obtained a good report through faith, received not the promise:
Heb 11:40 God having provided some better thing for us, that they without us should not be made perfect.
OT saints believed in the promise of the coming Messiah, but died in faith without the new birth. It seems to me then, that they are made perfect without sin as Adam was before the fall, but not glorified as the Church will be with Christ. If my assessment is correct, those who believe in the salvation of Christ would also be saved, but not part of the glory of the Church like the OT saints.
Will they/we look like Moses and Elijah did on the mount at the transfiguration when they appeared in their glorified Bodies??
The disciples saw them in their glory, even recognized exactly who they were, yet that vision in no way prevented them form understanding that they (disciples) were still sinful mortals in need of a savior, so your cause/effect scenario doesn't seem to hold up to the scriptural evidence.
When I shared the story of Adam naming the animals, I did not state all that God was showing me. Adam did not name the animals at all. God did. What Adam did was see into the spirits and restated the names that God used to speak the animals into existence. Likewise, when he saw the woman he saw into her spirit and realized that it was his own.
Moses and Elijah were not glorified like Christ and the Church. They were perfected like Adam before the fall. However, that is not relevant because none of the disciples had ever seen Moses nor Elijah before, even if they appeared as ordinary fallen men. They knew who they were in the spirit, just as Peter, by the Father speaking to his spirit, was able to declare that Jesus was the Messiah.
Mat_16:17 And Jesus answered and said unto him, Blessed art thou, Simon Barjona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.
Where is the evidence that Christ's once for all sacrifice on the cross, at that point, becomes null and void, indeed becomes wholly ineffectual for the redemption of those mortals, and instead the resurrection of an obsolete, vanished, less effective covenant where the blood of Bulls and goats is shed to atone for sins, must be set back up?
The blood of bulls and goats NEVER atoned for anyone sins. They were types and shadows of the sacrifice that Christ would provide to teach them about Christ's sacrifice to come. All OT saints who were saved were saved by their faith in the promise of the coming Redeemer.
Isa_59:20 And the Redeemer shall come to Zion, and unto them that turn from transgression in Jacob, saith the LORD.
Likewise, in the millennium, all those born during that time who understand the teaching of the sacrifice and put their faith in the redemption already done by Christ, will be saved in the end, but will not be part of the glorified Church. They will be saved just like the OT saints who believed God's promise of Messiah.
But, honestly, I am merely speaking academically. I am a point in my walk with Christ that I believe we will all be wrong in our assumptions about the future just as the Jews who believed Jesus would come as a conquering king to overthrow Rome were wrong.
I am skeptical of all doctrines of eschatology. We know that in both Daniel and Revelations both writers are told to not write what they saw (Dan. 12:9 & Rev. 10:4), and Jesus told his disciples,
Mat_24:36 But of that day and hour knoweth no man, no, not the angels of heaven, but my Father only.
In other words, God does not want us to know everything because he wants us to watch and pray as things unfold, and to be ready when things happen unexpectedly. There is nothing wrong in speculating and thinking upon what we do know as recorded in Holy Writ, but our confidence must always remain in Christ, not our understanding.
