babyys, as promised:
Revelations 20: 11 Then I saw a great white throne and him who was seated on it. Earth and sky fled from his presence, and there was no place for them. 12 And I saw the dead, great and small, standing before the throne, and books were opened. Another book was opened, which is the book of life. The dead were judged according to what they had done as recorded in the books. 13 The sea gave up the dead that were in it, and death and Hades gave up the dead that were in them, and each person was judged according to what he had done. 14 Then death and Hades were thrown into the lake of fire. The lake of fire is the second death. 15 If anyone's name was not found written in the book of life, he was thrown into the lake of fire.
Matthew Henry's commentaries on
Revelations 20:11-15 After the events just foretold, the end will speedily come; and there is no mention of any thing else, before the appearing of Christ to judge the world. This will be the great day: the Judge, the Lord Jesus Christ, will then put on majesty and terror. The persons to be judged are the dead, small and great; young and old, low and high, poor and rich. None are so mean, but they have some talents to account for; and none so great, as to avoid having to account for them. Not only those alive at the coming of Christ, but all the dead. There is a book of remembrance both for good and bad: and the book of the sinner's conscience, though formerly secret, will then be opened. Every man will recollect all his past actions, though he had long forgotten many of them. Another book shall be opened, the book of the Scriptures, the rule of life; it represents the Lord's knowledge of his people, and his declaring their repentance, faith, and good works; showing the blessings of the new covenant. By their works men shall be justified or condemned; he will try their principles by their practices. Those justified and acquitted by the gospel, shall be justified and acquitted by the Judge, and shall enter into eternal life, having nothing more to fear from death, or hell, or wicked men; for these are all destroyed together. This is the second death; it is the final separation of sinners from God. Let it be our great concern to see whether our Bibles justify or condemn us now; for Christ will judge the secrets of all men according to the gospel. Who shall dwell with devouring flames?
CE's layman's explanation: apparently the persons appearing in this scenario does not seem to have salvation, otherwise, they'd be in heaven already. these people seem to have died, or perished, or buried. Yet their bodies are resurrected to face the judge to account for their lifes. I'd say babies and those who have not heard the gospel will fall into this category. Whether in this modern times of high technology that it is possible for people NOT to have heard the gospel is another issue.
I need to state that Bible commentaries are written by scholars, but human nontheless, the issue of whether unsaved ignorant individuals have been discussed substantially in various church and apologetics websites and there is no universal answer.
