Your servant ma'am.
There are two books that contain the title “book of life”. The Book of Life where our name is written
at conception, and the Lambs Book of Life where our names are written when
we’re born again. Look at the separate references to them…
Book of Life
Revelation 20:12 And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works.
Revelation 22:19 And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.
Lamb’s Book of Life
Revelation 13:8 And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world.
Revelation 21:27 And there shall in no wise enter into it any thing that defileth, neither whatsoever worketh abomination, or maketh a lie: but they which are written in the Lamb’s book of life.
So, I believe without a shadow of a doubt that there are two books of Life. The first is “the” Book of Life, which I believe contains our name at birth. And then there is the “Lamb’s” Book of Life which contains our names once we are born again. Read these verses more than once, and see if you can see my point.
