Question: Does the Book of Life support Calvinism?

Question: Why does Revelation:17:8The beast that thou sawest was, and is not; and shall ascend out of the bottomless pit, and go into perdition: and they that dwell on the earth shall wonder, whose names were not written in the book of life from the foundation of the world, when they behold the beast that was, and is not, and yet is.
See All... (and maybe Revelation:13:8And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world.
See All..., depending on the translation used) refer to those “whose names were not written in the book of life from the foundation of the world...”? Could that, coupled with Psalm:69:28Let them be blotted out of the book of the living, and not be written with the righteous.
See All..., Revelation:3:5He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels.
See All..., and Revelation:22:19And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.
See All... mean that the names of all mankind are in the Book of Life, then later blotted out one by one as each Christ-rejecter crosses the line of final renunciation? I always thought that only after we believed the gospel were our names written in the Book of Life. If this were not the case, wouldn’t Calvinists say, “See! He has already chosen those whom He will save; their names are already written down before the foundation of the earth!”?

Answer: Several verses speak of God blotting or not blotting names out of the book of life: “I will not blot out his name out of the book of life…” (Revelation:3:5He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels.
See All...); “God shall take away his part out of the book of life…” (Revelation:22:19And if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city, and from the things which are written in this book.
See All...); “...if thou wilt forgive their sin—; and if not, blot me, I pray thee, out of thy book which thou hast written.... And the LORD said unto Moses, Whosoever hath sinned against me, him will I blot out of my book” (Exodus:32:32-33 [32] Yet now, if thou wilt forgive their sin--; and if not, blot me, I pray thee, out of thy book which thou hast written. [33] And the LORD said unto Moses, Whosoever hath sinned against me, him will I blot out of my book.
See All...).

These references to blotting out of the book of life allow only two possibilities: 1) everyone’s name is written in the book of life from eternity past, indicating God’s desire for all to be saved, until they have irrevocably rejected Christ, when their name is blotted out; or 2) when a person gets saved, his name is placed in the book of life for the first time, and when He later turns against Christ, his name is blotted out. Neither of these fits Calvinism. The first denies that God only intends to save a select elect, and the second denies the eternal security of the redeemed.

References to those “whose names are in the book of life” (Philippians:4:3And I intreat thee also, true yokefellow, help those women which laboured with me in the gospel, with Clement also, and with other my fellowlabourers, whose names are in the book of life.
See All...; Revelation:21:27And there shall in no wise enter into it any thing that defileth, neither whatsoever worketh abomination, or maketh a lie: but they which are written in the Lamb's book of life.
See All...) and those “whose names are not written in the book of life of the Lamb slain from the foundation of the world” (Revelation:13:8And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world.
See All...; 17:8; 20:15) offer no clue as to how or why names are written or are not written there. They only tell us that at the end of history, some names will be found, and some names will not be found written therein. But the fact that names can be and in fact are blotted out of the book of life is clear.

Of the two alternatives above, since the second one, which allows for some of the redeemed to lose their salvation, contradicts Christ’s clear promise (“...shall not come into condemnation, but is passed from death unto life”—John:5:24Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.
See All...), we must opt for the first. Comparing all of the verses, we can only conclude that, in keeping with God’s desire that all be saved, from eternity past every person’s name is written in the book of life of the Lamb, slain from before the foundation of the world. Whose names are blotted out? The names of those who refuse to yield to the wooing of the Holy Spirit. For this sin, there is no forgiveness (Mark:3:28Verily I say unto you, All sins shall be forgiven unto the sons of men, and blasphemies wherewith soever they shall blaspheme:
See All...; Luke:12:10And whosoever shall speak a word against the Son of man, it shall be forgiven him: but unto him that blasphemeth against the Holy Ghost it shall not be forgiven.
See All...).

Thus there is nothing in what Scripture says about the “book of life” to give any comfort to Calvinists, but only discomfort.
