I believe you are confused about this matter. Since the Tree of Life in Eden implied that eternal life was for all humanity, and God desires the salvation of every human being, the Book of Life has the names of all people. However as they are confronted with the Gospel or the living God, they must choose to obey or disobey. And those who disobey the Gospel, and reject Christ and His salvation, are BLOTTED OUT of the Book of Life. The Bible says that God has no pleasure in the death of the wicked (which implies eternal death).
Agree, All men naturally born, are Entered by Name, into "Gods Book of Life"...
We can learn the history of men, (our OT examples) who lived and physically died;
Some, believing IN God...
Some, rejecting belief IN God...
The believing Names remain in Gods Book of Life...
The rejecting Names become blotted out of Gods Book of Life....
(Those believing...who CONTINUED in BELIEVE, ie enduring to their end of physical life...Received their Salvation when their physical life ended)
Moving into the NT, a NEW Covenant, a NEW Promise. (Receiving their Salvation "DURING" their Physical Life,)
* BY Spiritually giving their LIFE unto death, crucified with Christ...
Receiving Salvation of their soul.
Receiving Quickening of their spirit.
Living their Spiritual LIFE, IN the Risen Lords Body.
THESE ^ are Never Subject to being Blotted our the Gods Book of Life.
THESE ^ are ADDITIONALLY Names entered INTO, the Lambs Book of Life, which their NAME can NEVER Be BLOTTED OUT.
WHY those TWO BOOKS?
Because there were TWO Teachings.
* The First...to BABES...(ancient men, with less knowledge given, without history, without experience..
(Same concept, as we teach our children, little by little bits of information, until they grow, mature, can comprehend more knowledge)
* the First...Hebrews, Tribes, ONLY KNEW of God.
* Enter the Last...Gods CHRIST the Lord...
to children with 4,000 years of examples, experiences, history...
* and A NEW TESTAMENT, NEW COVENANT, NEW OFFERING...SALVATION NOW...before physical death...
This Offering of SALVATION NOW...
IS predicated ON a mans Heartful Confession of BELIEF...IN BOTH...
"God and His Christ."
A mans NAME ENTERED into The LAMBS BOOK OF LIFE...
Receives ONCE and Forever...
Forgiveness, The Lords acceptance of that mans body dead, crucified with Christ, gifts that man with Salvation of his soul, gifts that mans with a Quickening of his spirit...
AND...Just as in Noah's DAY...the Lord God, Shall KEEP that man FROM WRATH TO COME...by the same manner the Lord God KEPT Saved Noah from Wrath upon the Earth...
Noah was lifted UP, "above" the Face of the Earth...TO the "Face of the waters".
The Face of the Earth was destroyed.
Those IN Lambs Book of Life;
Shall be Lifted UP, "above" the Face of the Earth...TO the "Face of the water...Clouds".
(This is BEFORE Tribulation)
Those ON Earth...shall suffer, THE LAMBS WRATH...as men Accept belief in the Lamb...
Their Wrath ceases, they become SAVED, and their body physically dead. THEIR saved souls, WAIT on earth, for other souls to be saved, Their names, entered into the Lambs BOOK.
(This is DURING first part of Tribulation)
Second part of Tribulation...
The DEVILS WRATH appears. Living body's are KILLED... Some are accepting the Lords Salvation...(names entered into the Lambs Book) ...Some are not. (Names Blotted out of Gods Book)
Third part of Tribulation...
Those with and IN the Lord God...Separated.
Names IN Gods Book, IN Lambs Book, souls and spirits with the Lord God.
Gods Wrath, upon remaining men on earth "whose names are blotted out"...
THREE WRATHS TO COME...
The BOOKS, of God, of the Lamb...
Are the Testimonies of WHO is or is NOT Subject to Which "of" the Three wraths, or Subject to ALL of the Three wraths to come.
* Rev 6:16....(first)
...Lambs' Wrath
* Rev 12:12...(second)
...Devils Wrath
* Rev 16:1 (third)
...Gods Wrath
Book(s) are opened at Judgement.
The Book of Life.
The Lambs Book of Life.
(And other books of evidence, ie a mans works that glorified God)
Glory to God,
Taken
