'Book of Life' in the Bible

Yes, and I ask you also, true yoke-fellow, to help these women who have struggled at my side in the cause of the gospel, together with Clement also and the rest of my fellow workers, whose names are in the book of life.

He who overcomes shall be clothed in white garments, and I will not blot out his name from the Book of Life; but I will confess his name before my Father and before his angels.

and all who dwell on earth will worship it, every one whose name has not been written from the foundation of the world in the book of life of the Lamb that was slain.

The beast that you saw was, and is not, and is about to come up out of the abyss and go to destruction. And those who dwell on the earth, whose names have not been written in the book of life from the foundation of the world, will wonder when they see the beast, because he was and is not and will come.

And I saw the dead, great and small, standing before the throne, and books were opened. Also another book was opened, which is the book of life. And the dead were judged by what was written in the books, according to what they had done.

And if anyone's name was not found written in the book of life, he was thrown into the lake of fire.

Nothing unclean shall enter it, nor any one who practices abomination or falsehood, but only those whose names are written in the Lamb's book of life.
