According to Pentecostals, when were names added to the Book of Life? According to Pentecostals, are names added to the Book of Life anywhere in the Bible (after Creation)?

I see only examples of names remaining in or being wiped out. I don’t see names being added.


  “The one who conquers will be clothed thus in white garments, and I will never blot his name out of the book of life. I will confess his name before my Father and before his angels.”
  ‭‭Revelation‬ ‭3:5‬ ‭ESV‬‬


In order to never be blotted out it’s implied you were already written in. When was it written in?

What is the Pentecostal Charismatic view?
I suppose I am qualified to answer this question as a “Pentecostal”.

From my perspective (as the question asks), since all mention of the Book of Life refers to names that are already written in it, then every name has been written in it from a time-independent source/power/etc, and therefore names can only be removed from it from a time-dependent human point of view. 

My reading usually begins in KJV. Revelation 13:8 looks appealing but one cannot be sure that “the foundation of the world” describes the Book of Life or the Lamb or both. 


  “And 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.” Revelation 13:8 KJV


AMPLIFIED seems to support my initial perspective that “the foundation of the world” does pertain to the Book of Life. 


  “All the inhabitants of the earth will fall down and worship him, everyone whose name has not been written since the foundation of the world in the Book of Life of the Lamb who has been slain [as a willing sacrifice].” REVELATION‬ ‭13:8‬ ‭AMP‬‬


ESV is similar. 


  “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.” Revelation‬ ‭13:8‬ ‭ESV‬‬


GW and NIV seem to point toward “the foundation of the world” pertaining only to the Lamb.


  “Everyone living on earth will worship it, everyone whose name is not written in the Book of Life. That book belongs to the lamb who was slaughtered before the creation of the world.” Revelation‬ ‭13:8‬ ‭GW‬‬
  
  “All inhabitants of the earth will worship the beast—all whose names have not been written in the Lamb’s book of life, the Lamb who was slain from the creation of the world.” Revelation‬ ‭13:8‬ NIV‭


To add to my perspective, I’d say the question of when the names were written is an unfathomable concept since I stated that a power “outside of time” was/is the author.
