Perhaps the Book of Life is opened as the PROOF that they were not saved? The Book of life/Lambs Book of Life sounds like all lives are written in it but only those who remain - are not blotted out - will be with God. Moses pleaded with God to blot his name out of the book rather than see Him not forgive the sins of the children of Israel (see Exodus 32:32). Then in Revelation 3:5 we learn, "Like them, the one who is victorious will be dressed in white. And I will never blot out his name from the book of life, but I will confess his name before My Father and His angels."
The "other book(s)" were opened to show the works of each one to be judged so they are the record of their life and all the works they had done whether good or evil. I believe there will be some kind of degree of hell - some have it worse than others based upon their whole life. I see the GWT Judgment being the ultimate judgment of the lost - everyone that remains unsaved at the end of the millennial reign of Christ. This would be all the lost who died prior to the Millennium as well as those who are born during the 1000 years who reject Christ. It's hard to imagine people will STILL reject Christ when He is present reigning in pure righteousness and justice, but there will be many. How many chances will humanity get???!!!
I tend to think every lost, unsaved person, that has ever lived, including many church members, will be standing tall, in front of God.
It is definitely, hard to imagine, that people born during the millennial kingdom, will refuse to be born anew from above. Utterly unbelievable. They will see him physically, hear him physically speak, know exactly who he is, the spotless Son of God, ruling the earth, with a rod of iron, and they STILL reject Him. Unbelievable, but they do.
Other issues, I wanted to ask your opinion on. I had heard that, obviously, there will be mortal people, who will physically survive the tribulation period, both true believers and also unbelievers. I had heard, and its quite probably wrong, that all the unbelievers, would be killed off, and only true, mortal believers, will be allowed to enter the millennial kingdom. They will do, what people do best, start making babies again. 😁
We all know what PTSD is. After having survived the worst period in history, can you imagine the PTSD the tribulation survivors will experience? I cant help but feel, that only God can, and will have to treat the survivors, for PTSD. Make sense? 🤗😆
See my answer above.
I hope that
2 Corinthians 1:13
For we do not write you anything you cannot read or understand.
... is true.
