King James Bible
Book of Life — What is it? In other words, the Book of Life is the names of the redeemed—those who will live with God forever in heaven. In this verse, we learn that overcomers will be clothed in white a symbol of purity as our name is acknowledged to God. The lake of fire is the destination created for Satan and it looms eternally before those who reject and rebel against God. The inhabitants of the earth whose names have not been written in the book of life from creation of the world will be astonished when they see the beast, because he once was, now is not, and yet will come. Earth and sky fled from his presence, and there was no place for them.
What does the Bible say about? And all who dwell on earth will worship it, everyone whose name has not been written before the foundation of the world in the book of life of the Lamb who was slain. The one who conquers will be clothed thus in white garments, and I will never blot his name out of the book of life. I will confess his name before my Father and before his angels. But nothing unclean will ever enter it, nor anyone who does what is detestable or false, but only those who are written in the Lamb's book of life. And I saw the dead, great and small, standing before the throne, and books were opened.
