At least three books are maintained before God. Revelation 20:12 says “books” which is plural (i.e., at least two) plus the Book of Life. What are the books?
(Revelation 20:12 KJV) 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.
(Daniel 7:10 KJV) A fiery stream issued and came forth from before him: thousand thousands ministered unto him, and ten thousand times ten thousand stood before him: the judgment was set, and the books were opened.
(Malachi 3:16 NKJV) Then those who feared the LORD spoke to one another, And the LORD listened and heard them; So a book of remembrance was written before Him For those who fear the LORD And who meditate on His name.
