God is not even done with His covenant to Noah and the Nations. The 3.5 year tribulation is the judgment on the church, the house of Jacob, and the Nations. The Nations go through all 3 sets of Judgments. The house of Jacob goes through the first 2 sets. The church only goes through the Seals. The church and OT Saints, it does not matter if they are Jew or Gentile, will never be removed from the Lamb's book of life. It is spiritually and physically impossible. The body of Christ is taken out even before the 7th Seal is opened. When the 7th Seal is opened the book will be opened, and names will be removed. Names will never, ever be added. During the Seals and Thunderings will be when humans left will chose to remain in the book or not. The 144K are sealed, and cannot be unsealed. They will be whiteness as only the future can describe. We are not told how or what they do. At some point the harvest of the nations and modern Jews will be reaped. Then God will deal directly with any one left alive on earth. Of course the Vatican will want to have a say. They just missed the first and second harvest. Well yes, the woman of Babylon/Rome is still around.
The Second Coming will happen in April of 2023. Christ will make a deal with Satan that lets him have 3.5 years starting on Wednesday of that week. The last 3.5 days of the week will be postponed until the end of that time. There will only be 2 witnesses. The choice will be the mark, and name removed from the Lamb's book of life, or chopping the head off. Those whose heads are chopped off remain in the Lamb's book of life. Revelation 20:4-6
4 Then I saw thrones, and those seated on them received authority to judge. And I saw the souls of those who had been beheaded for testifying about Yeshua and proclaiming the Word of God, also those who had not worshipped the beast or its image and had not received the mark on their foreheads and on their hands. They came to life and ruled with the Messiah for a thousand years.
5 (The rest of the dead did not come to life until the thousand years were over.) This is the first resurrection.
6 Blessed and holy is anyone who has a part in the first resurrection; over him the second death has no power. On the contrary, they will be cohanim of God and of the Messiah, and they will rule with him for the thousand years.
