The Bible talks about record book(s) in heaven. There is a book which records the deeds which everyone who has ever been born have committed and there is a book called the BOOK OF LIFE OF THE LAMB in which only those born of God have their names written in for eternity.
“And I saw a great white throne, and him that sat upon it, from whose face the earth and the heaven fled away; and there was found no place for them. And I saw the dead, the great and the small, standing before the throne; and books (plural) were opened: and another book was opened, which is THE BOOK OF LIFE: and the dead were judged out of the things which were written in the books according to their works. And the sea gave up the dead that were in it; and death and Hades gave up the dead that were in them: and they were judged every man according to their works. And death and Hades were cast into the lake of fire. This is the second death, even the lake of fire. And if any was not found written in the book of life, he was cast into the lake of fire.” Revelation 20:11-15
Those who do not receive salvation will be blotted out of the book of life after the judgment but the book of life of the lamb where the over comers names are written will not be blotted out. Why? Because they OVERCOME BY THE BLOOD OF THE LAMB AND THE WORD OF THEIR TESTIMONY.
The Bible tells us in many scriptures(refer to my other blogs on the topic) that those who has been saved and born of God are kept by the power of the Holy Spirit until the end.
“Who art thou that judgest another man’s servant? to his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand.” Romans 14:4
“Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy,” Jude 1:24
“But thou hast a few names in Sardis that did not defile their garments: and they shall walk with me in white; for they are worthy. He that overcometh shall thus be arrayed in white garments; and I will in no wise blot his name out of the book of life, and I will confess his name before my Father, and before his angels.” Revelation 3:4,5
Who is it that overcomes? “For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.” 1 John 5:5
During the tribulation all those whose names are not written in the Lamb’s Book of Life will worship the Antichrist: “And all that dwell on the earth shall worship him, every one whose name hath not been written from the foundation of the world in the book of life of the Lamb that hath been slain.” Revelation 13:8
“The 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.”Revelation 17:8
Add iniquity unto their iniquity; And let them not come into thy righteousness, Let them be blotted out of the book of life, And not be written with the righteous.” Psalm 69:28
“And all who dwell on the earth will worship [the beast], everyone whose name has not been written from the foundation of the world in the book of life of the Lamb who has been slain.” Revelation 13:8.
This verse tells us that those whose names are written in the Lamb’s book of life “from the foundation of the world” will not worship the beast.
“The beast that you saw was and is not, and is about to come up out of the abyss and to go to destruction. And those who dwell on the earth, whose names have not been written in the book of life from the foundation of the world, will marvel, when they see the beast, that he was and is not and will come.” Revelation 17:8,
In conclusion, whether there is one book or many books,is unclear BUT what is very clear is that your name must be in the lamb’s book of life to be saved. Those blotted out are those who never receive salvation because scriptures confirm that those born of God will overcome because God is able to keep them from falling !
“Ye have not chosen me, but I have chosen you, and ordained you, that ye should go and bring forth fruit, and that your fruit should REMAIN: that whatsoever ye shall ask of the Father in my name, he may give it you.” John 15:16
