God’s covenant with Israel and the Jews is eternal, and cannot be broken, and God is not going to leave them in their fallen condition. The time of Jacob’s trouble is going to be the means by which He restores His chosen people back to a right relationship to Himself.
Yes, Revelation is absolutely written in chronological order of events. The Church Age, the Rapture of the Church, the time of Jacob’s trouble, Armageddon, the Thousand Year Reign of King Jesus, Gog and Magog, judgement, new heaven and new earth, eternity.
God has given Satan every advantage, every angle and allowed him to use every trick in the book so that when the Devil is defeated at the Battle of Armageddon, his fall will be without precedence. It will be the greatest defeat in human history, watched by the entire world, as the Devil and his army get crushed like grapes in a winepress.
