You said the soul is eternal and yet followed it up with scripture that says the opposite: “but rather fear Him who is able to destroy both soul and body in hell.”
This is the same scripture I have used in the past to show people that, in fact, the sould can be destroyed.
Regarding the rest of your post, yes, total destruction is a thing to be feared to those who value life.
Also, regarding this part of the scripture you quoted: “...has authority to throw you into hell.” Hell itself is actually destroyed in the end (check out revelation). It is also fascinating to study what “hell” actually is.
But the Gospels are called such for a reason. Thanks to Adam we are all destined to eventually die in all ways. It is the default condition of every man ever born. But Jesus offers a better way. It is what I choose. Rather, He is who I choose. His blood as the attonement for my sin, that is - and eternal life in His presence as opposed to death, to never be reversed.
Once again the attempts by the deceiver. (I’m referring to Satan, not you cuban leaf) Let’s look at that verse you allude to.
Revelation 20:14 Then death and Hades were thrown into the lake of fire. The lake of fire is the second death.
The Greek word for death there is thánatos.
2288 thánatos (derived from 2348 /thnḗskō, "to die") – physical or spiritual death; (figuratively) separation from the life (salvation) of God forever by dying without first experiencing death to self to receive His gift of salvation.
That does NOT mean annihilation or extinction into nothingness.
The word Hades is not the same as “the lake of fire”. Hades is the unseen place where those not saved are until they are cast into “the lake of fire”.
86 hádēs (from 1 /A "not" and idein/eidō, "see") – properly, the "unseen place," referring to the (invisible) realm in which all the dead reside, i.e. the present dwelling place of all the departed (deceased); Hades.
>> It is also fascinating to study what “hell” actually is.<<
Indeed it is. It is also a very sobering study if done thoroughly. There are three words that have been translated “hell”. There is Sheol, Hades, and Ghehenna. Not one of them is “the lake of fire” as seen in Revelation. Sheol is simply the grave. Hades is the holding place for those who have rejected Christ. Ghehenna is an example used for illustrative purposes and was a valley where dead animals and refuse was burned outside of Jerusalem. It continually burned as trash etc was being continually added. The term was used as a visual of what “the lake of fire” would look like.
For those taking solace in the false teaching that those who reject Christ will simply be annihilated into extinction will be bitterly brought to the realization of truth should they choose to reject Christ.
How is annihilation something to be "feared"? Even those who "value life" do so fully knowing that physical life is finite. Atheists, like Christopher Hitchens, just love the idea that there is nothingness after death. He said he couldn't imagine a WORSE way to spend eternity than in worshiping and glorifying God. Somehow, I do not think this was how Jesus meant that we should fear hell. If it is not an eternal, conscious torment of some kind, then it is no deterrent at all. The ungodly delight in that false theology which SHOULD be a clue that it is wrong.
