BOOK OF LIFE
Registration of people as living.
One of them (also called simply the book of God), may be a book of those who only have names because they live, and therefore from which names can be blotted out (Ex. 32:32, 33; Ps. 69:28 ; Rev. 3:5; 22:19).
Another of them is the book of the saved, from which no one will be blotted out (Phil. 4:3; Rev. 13:8; 17:8; 20:12, 15; 21:27).
A third (called simply “the book”) contains the names of the remnant of Israel (Dan. 12:1).
