As an English teacher, I can confidently say that smoke rising forever doesn’t imply eternal torment. The bodies are being burned after their second death and there are a lot of bodies, too. This is less about reading comprehension and more about Bible illlteracy.
Revelation 20:14,15
14Then Death and Hades were thrown into the lake of fire. This is the second death—the lake of fire.
15And if anyone was found whose name was not written in the Book of Life, he was thrown into the lake of fire.
Anyone not found in the book of life is cast into the lake of fire to undergo a second death. We’re talking about possibly billions of bodies being burned. Effectually, the smoke will rise forever.
Revelation 2:11 introduces the fact that the second death will have pain involved, but it isn’t permanent. The pain is a separate experience to the second death. Death is a permanent end to life.
Revelation 2:11
11He who has an ear, let him hear what the Spirit says to the churches. The one who overcomes will not be harmed by the second death.
Also, you should note, “smoke rising forever” is poetic language called apocalyptic language and it isn’t literal in Isaiah 34.
Isaiah 34:9,10
9Edom’s streams will be turned to tar,
and her soil to sulfur;
her land will become a blazing pitch.
10It will not be quenched—day or night.
Its smoke will ascend forever.
From generation to generation it will lie desolate;
no one will ever again pass through it.
so important questions. Is Edom still burning? Is there smoke rising forever there? Has no one passed through it again? The answers to all of those questions are no.
Now reconsider what you just said about it being impossible to have smoke that rises forever unless there is eternal torment. Those two things are not mutually exclusive according to the Bible, English grammar, or logic.
