The Final Victory of Christ
Jesus destroys His last enemies - a cleared-out Hell and Death - when they are thrown into the Lake of Fire! After that, everyone who was removed from Hell will be judged, their names not found written in the Book of Life, and they will bow the knee to Jesus and then also be thrown into the Lake of Fire. Why would Hitler bow the knee to Jesus when he knows he's about to be destroyed in the Lake of Fire? I surmise that it's because Hell reduced him to the truth.
