And I saw the dead, the great and the small, standing before the throne, and books were opened; and another book was opened, which is the book of life; and the dead were judged out of the things written in the books, according to their works.

And if any one was not found written in the book of life, he was cast into the lake of fire.

And there shall not enter into it anything unclean, or that worketh abomination and falsehood; but only they that are written in the Lambs book of life.
