SInce the book of Revelation is written with so many inferences to the Old Testament Scriptures (for example, the two witnesses in Rev. 11as two olive trees in Zech 4), I suggest we look back to what this “book of life” (or book of the living as it is sometimes referred) as it pertains the the OT. The first instance of ‘blotting out’ occurrs in the mouth of Moses after returning from the Mount when it was discovered that the people made and worshiped a golden calf in Exodus 32. God was apparently wroth of the incident that it seemed fit to destroy the people (and presumably to start over with Moses to remake the nation):
*"And the LORD said unto Moses, I have seen this people, and, behold, it is a stiffnecked people:
Now therefore let me alone, that my wrath may wax hot against them, and that I may consume them: and I will make of thee a great nation." - Exodus 32:9-10 *
But the exasperated Moses intervenes telling God that Egypt will mock God for delivering them only to destroy them and reminding God of the Abrahamic Promise, in which case God repents of His intent:
*"And Moses besought the LORD his God, and said, LORD, why doth thy wrath wax hot against thy people, which thou hast brought forth out of the land of Egypt with great power, and with a mighty hand?
Wherefore should the Egyptians speak, and say, For mischief did he bring them out, to slay them in the mountains, and to consume them from the face of the earth? Turn from thy fierce wrath, and repent of this evil against thy people.
Remember Abraham, Isaac, and Israel, thy servants, to whom thou swarest by thine own self, and saidst unto them, I will multiply your seed as the stars of heaven, and all this land that I have spoken of will I give unto your seed, and they shall inherit it for ever.
And the LORD repented of the evil which he thought to do unto his people."*
Well, Moses was pretty whiffed when he witnessed himself of the evil in the camp that he threw down the Ten Commandments and shattered the tablets. After siding people up and having the people kill off three thousand, Moses makes another plea to God up on the Mount:
*"And Moses returned unto the LORD, and said, Oh, this people have sinned a great sin, and have made them gods of gold.
Yet now, if thou wilt forgive their sin–; and if not, blot me, I pray thee, out of thy book which thou hast written.
And the LORD said unto Moses, **Whosoever hath sinned against me, him will I blot out of my book. **
Therefore now go, lead the people unto the place of which I have spoken unto thee: behold, mine Angel shall go before thee: nevertheless in the day when I visit I will visit their sin upon them.
And the LORD plagued the people, because they made the calf, which Aaron made."*
A couple things to note here. Moses intercesses to spare the people and forgive them or else blot his (Moses’) name out of “thy book which thou hast written”. We can presume that God does have such a book in which names are already written, which currently includes the name of Moses. Second, God makes the pronouncement that “whosoever sinned against me, him will I blot out of my book”. But it’s obvious that the whole camp of Israel sinned against God, including Aaron, yet God spared the majority of the people, howbeit not without plagues.
Now Aaron37’s contention is that God only blots out names from the book of life, never adds to it. But we all deserve to have our names blotted out as all have sinned.
In Psalm 69, which contains Messianic Prophecies of Christ in the Cross (ex. see verse 21, cf. Matt 27:34), the Psalmist here pleads with God to “Let them be blotted out of the book of the living, and not be written with the righteous.” vs 28. Yet what did Jesus on the Cross say? “Father, forgive them; for they know not what they do.” Not the kind of attitude that is willing to blot out names, now, is it?
But finally, we come to book of Malachi 3. Notice here that it speaks of a refiner’s fire, not to destroy, but *to purify * (vs 3). And later in the same chapter we have this interesting passage speaking to the sons of Jacob which are not consumed (vs 6):
*"And now we call the proud happy; yea, they that work wickedness are set up; yea, they that tempt God are even delivered.
Then they that feared the LORD spake often one to another: and the LORD hearkened, and heard it, and a book of remembrance was written before him for them that feared the LORD, and that thought upon his name."*
Here this book of rememberance is being written as people fear the Lord and think upon His name (Now what name might that be, I wonder?). The wicked are delivered from being consumed as they learn that fear, all at the day of His coming! Names can be added!
