hi Heavenly Pilgrim,
Trying to catch up but won't get very far tonight.
Tried to quote, but it didn't when I logged in.
So, off the cuff.
Consider this: Psalm 69, a psalm of David and Messianic in nature:
26For they persecute him whom thou hast smitten; and they talk to the grief of those whom thou hast wounded.
27Add iniquity unto their iniquity: and let them not come into thy righteousness.
28Let them be blotted out of the book of the living, and not be written with the righteous.
I would recommend a review of this, as you seek to understand the book of life.
You say there are two books in Revelation 20-
12And I saw the dead, small and great, stand before God; and the books (plural)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.
Though it is not said what books are referenced, I would offer two suggestions:
1-The written word of God, by which it is reasonable that they will be judged from. At this point, they are judged, whereas Christians have already been judged, and there remains no condemnation for them.
As there will be for these.
2-Among these books we may find the book of remembrance, if this isn't the book of life itself:
Malachi 3:16 (King James Version)
16Then 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.
Just a few thoughts to ponder.
God bless.
