'Book of Life' in the Bible

The person who conquers in this way will wear white clothes, and I will never erase his name from the Book of Life. I will acknowledge his name in the presence of my Father and his angels.

All those who had become settled down and at home, living on the earth, will worship it, everyone whose name had not been written in the Book of Life belonging to the lamb that had been slaughtered since the foundation of the world.

The beast that you saw existed once, but is no longer, and is going to crawl out of the bottomless pit and then proceed to its destruction. Those living on earth, whose names were not written in the Book of Life from the foundation of the world, will be surprised when they see the beast because it was, is no longer, and will come again.

I saw the dead, both unimportant and important, standing in front of the throne, and books were open. Another book was opened the Book of Life. The dead were judged according to their actions, as recorded in the books.

Anyone whose name was not found written in the Book of Life was thrown into the lake of fire.

Nothing unclean, or anyone who does anything detestable, and no one who tells lies will ever enter it. Only those whose names are written in the lamb's Book of Life will enter it.
