I'm just going to comment about the things i agree with you on ClaudiaT.
ClaudiaT you posted verses that aline with what the second death is.
The confusion for too many comes in with what they have been taught or not about , figures of speech .
Like everlasting destruction.
Instead of following the scriptures , and read it as a destruction, that there is no return from.
Instead people see it as what they have been taught for a very long time, that means eternal suffering.
There are more scriptures that are more descriptive and appear that there is eternal suffering, but thats only if we were to ignore some of the scriptures ClaudiaT posted.
When we take in all the Bible has to teach about this, you'll see the lake of fire causes the death of the soul, the second death
( Revelation 20:14 )
You have other scripture that you can reference, that use the term "blotting out " .
Luke 10:20
King James Version (KJV)
20 Notwithstanding in this rejoice not, that the spirits are subject unto you; but rather rejoice, because your names are written in heaven. (note Ephesians 1:3-6 )
Revelation 13:8
King James Version (KJV)
8 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 17:8
King James Version (KJV)
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.
Deuteronomy 32:31-33
King James Version (KJV)
31 For their rock is not as our Rock, even our enemies themselves being judges.
32 For their vine is of the vine of Sodom, and of the fields of Gomorrah: their grapes are grapes of gall, their clusters are bitter:
33 Their wine is the poison of dragons, and the cruel venom of asps.
Psalm 69:26-28
King James Version (KJV)
26 For they persecute him whom thou hast smitten; and they talk to the grief of those whom thou hast wounded.
27 Add iniquity unto their iniquity: and let them not come into thy righteousness.
28 Let them be blotted out of the book of the living, and not be written with the righteous.
Exodus 32:32
King James Version (KJV)
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.
Revelation 3:5
King James Version (KJV)
5 He 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.
Paul even mentioned the soul, when he brought in that subject in 1 Cor 15. At the end, how the soul can also be mortal, or immortal through victory in Christ.
The mortal state of the soul he mentions near the end of the chapter around verse 45 - , " mortal " in greek means liable to die "
Die where , when ? At the very end, at the great white throne judgment, at the end of the Lord's Day. Rev 20 .
