'Written in the Book' in the Bible

The beast you saw was, and is not, but is about to come up from the abyss and then go to destruction. The inhabitants of the earth -- all those whose names have not been written in the book of life since the foundation of the world -- will be astounded when they see that the beast was, and is not, but is to come.

And I saw the dead, the great and the small, standing before the throne. Then books were opened, and another book was opened -- the book of life. So the dead were judged by what was written in the books, according to their deeds.

If anyone's name was not found written in the book of life, that person was thrown into the lake of fire.
