There is no foundation for the book being spoken of as the book of the living. There is no scripture that ever introduces a book of the living. You have to assume that into the passage.
abut there’s no scripture saying the book of the living is the book of life ! We spin in so many circles in this place
I’m sure this doesn’t have a thing to do with it either because it doesn’t say book of life
“And at that time shall Michael stand up, the great prince which standeth for the children of thy people: and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book.”
Daniel 12:1 KJV
Probably not related to the great tribulation or resurrection or book of life …
