The Book is more of a Book of the Called, and not a Book of just the chosen. That's why there is a winnowing or blotting or deleting process, but not an adding process.
Ok. So let's say this is true. It starts out as a book of the called but gets smaller as people are deleted, and we end up with only the chosen. This book would therefore not contain everyone who ever lived because not everyone is called? [eg those of other faiths, or atheists, or those ignorant of Christ].
This would correspond to the verse that says, many are called but few are chosen? So we would start out with many in the book of life and end up with few?
And would those few be described here:
9After this I beheld, and, lo,
a great multitude, which no man could number, of all nations, and kindreds, and people, and tongues, stood before the throne, and before the Lamb,
clothed with white robes, and palms in their hands;
10And cried with a loud voice, saying, Salvation to our God which sitteth upon the throne, and unto the Lamb.
--Rev 7
Revelation 3:5
He that overcometh, the same shall be clothed in
white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels.
So we see a great multitude that no man could number clothed in the white raiment of the overcomer. All these started in the book of life from the foundation of the world and were never blotted out?
Revelation 17:8
The beast that thou sawest was, and is not; and shall ascend out of the bottomless pit, and go into perdition: and they that dwell on the earth shall wonder,
whose names were not written in the book of life from the foundation of the world, when they behold the beast that was, and is not, and yet is.
This says that 1)some were written into the book of life from the foundation of the world and 2) all of these will not be deceived by the beast [wonder at him]. We know from another passage that these that are not deceived are elect because it is not possible to deceive the elect.
Matthew 24:24
For there shall arise false Christs, and false prophets, and shall shew great signs and wonders; insomuch that,
if it were possible, they shall deceive the very elect.
So the beast is good at deceiving but not so good he will deceive the elect. Yet, we also see that the elect are predestined for this position--that would mean they could not be written into a book and then blotted out because predestination would forbid it--
28And we know that all things work together for good to them that love God, to them who are the called according to his purpose.
29For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.
30Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.
--Rom 8
So now we have Rom 8 telling us that these predestinated ones are the called according to his purpose, and he will be faithful to finish a work he started, meaning to glorify them. This group, then, is not getting blotted out of any book forever because Jesus is making sure not to lose a one. They are predestinated therefore they will be glorified. The elect cannot be deceived and they cannot be blotted out of any book. They are in fact among the judges at the great white throne as implied by this verse--
1 Corinthians 6:3
Know ye not that we shall judge angels? how much more things that pertain to this life?Ok, so maybe those written into the book from the foundation of the world are just the elect? And, maybe others will be added as they are introduced to Christ and become saved?
But you say none are ever added. That means you are ignoring those who are born into the kingdom, those posts we listed earlier--
The LORD will write in the register of the peoples: "This one was born in Zion." Selah--Psa 87:6
So God is entering the names of those born in the holy city--the new Jerusalem. It is a census of the citizens of heaven. Is there any reason why this would not be the book of life? If I am a born again citizen of God's holy city, would I, of all people, have a right to the life given by Christ?
3Glorious things are spoken of thee, O city of God. Selah.
5And of Zion it shall be said, This and that man was born in her: and the highest himself shall establish her.
--Psa 87
