If God the Father, Son, and Holy Spirit have different functions within the Godhead head then each member should have their own book in which they keep track for themselves, and in the end they should all agree together with each other. This is an interesting scripture here.....
1Jn 5:7 FOR THERE ARE THREE THAT BEAR RECORD in heaven, the Father, the Word, and the Holy Ghost: and these three are one. (KJV)
Some scholars do not believe that the verses, “ in heaven, the Father, the Word, and the Holy Ghost....” as some of the oldest original texts have them omitted. It makes no difference because the word “testify” which most translations use means “to bear record, or bear witness”. This means each member of the Godhead would have its own book, in which “RECORDS” are kept.
I will give you my understanding on this subject.
The “BOOK OF LIFE” is what God the Father uses to keep track of all who have been born on planet Earth. If a person dies without ever accepting Jesus Christ as their savior, that person's name is “blotted” out from the Book of Life. We know this to be true because of this scripture.....
20:15 And IF ANYONE'S NAME WAS NOT FOUND WRITTEN IN THE BOOK OF LIFE, HE WAS THROWN INTO THE LAKE OF FIRE.
A person's name must appear in the Book of Life, or they are cast into the lake of fire!!! Names are being added to, and taken away every day from this Book.
Then we have the “LAMBS BOOK OF LIFE”. I wonder to whom this book belongs? This is Jesus's own book, and all the names written in it were written before the foundation of the world. No one's name can ever be blotted out of the Lamb's Book of Life!! There are no scriptures anywhere in the Bible that says any name can be blotted out of this Book. The reason why is that God already knows every single person who will accept Jesus as their Savior, and he knew this before the foundation of the world.
Just because someone's name is written in the Lamb's Book of Life, that does not mean they have no choice in choosing Jesus as their savior. All the names in this book have been given a free will choice to choose to whom they will serve, it's just God already knew what their choice was going to be, so he wrote them into this Book!!
Rev 21:27 But nothing unclean will ever enter it (The Holy City of God) , nor anyone who does what is detestable or false, but ONLY THOSE WHO ARE WRITTEN IN THE LAMB'S BOOK OF LIFE.
Rev 13:8 and all who dwell on earth will worship it, everyone WHOSE NAME HAS NOT BEEN WRITTEN BEFORE THE FOUNDATION OF THE WORLD IN THE BOOK OF LIFE OF THE LAMB who was slain.
During the “tribulations” period every person whose name was NOT written in the Book of Life of the Lamb from the foundation of the world will worship the beast.
Then we have a book called, “THE BOOK OF REMEMBRANCE”. I believe this book belongs to the Holy Spirit because Jesus once said that when the Holy Spirit comes, he will bring to our remembrance everything he has spoken to us. Every time a person thinks about the Lord his God, and talks about him, everything is recorded in this book......
Mal 3:16 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.
I do not think the Lord forgets anything, except for our sins that we have confessed before him, nor does he need remembering what we have said, or thought. I think it is for our benefit that he keeps these records.(books) In the end, the only names that will be found in the Book of Life, and the Lamb's Book of Life will be his Church. The Holy Spirit will bear witness to these truths by bringing forth all that we have said and thought throughout our life here on earth.
There are three that bear RECORD the Father, Son, and the Holy Spirit, and they all three agree in one.
Rev 20:12 And I saw the dead, great and small, standing before the throne, and books were opened. Then another book was opened, which is the book of life. And the dead were judged by what was written in the books, according to what they had done.
