What the smoke of their torment?

The easiest way to understand this is with a timeline, starting with the return of Jesus:

Where all of those who rejected harmony and made it through the plagues and have demonstrated their darkness are consumed by His light.

The bodies of those who died at the brightness of Jesus' Second Coming will be scattered on the ground.

A gruesome detail is that the birds will feast on the dead bodies of the wicked.

It is a bit poetic that when Christ (the Bridegroom) reunites with His church (the Bride) the marriage supper, the guests are birds and the dinner is the flesh of fallen kings.

Only lucifer and the fallen angels remain on earth alive.

The bottomless pit refers to earth:

This was prophesied by the prophet Jeremiah:

So the birds who feasted on the fallen wicked bodies are no more, the cities of the earth are flattened and the earth is in a state similar to what it was before the beauty of creation.

The angel with the key and chain of earth imprisons lucifer and the fallen angels:

The earth is desolate for 1000 years with only lucifer and his angels left on the earth, forced to keep a 1000 year millennial sabbath.

For 1000 years, Satan will behold the results of his rebellion against the law of God. His sufferings are intense. He is now left to contemplate the part he has acted since he rebelled and to look forward with terror to the dreadful future when he must be punished. ” From Here to Forever (HF 399.2)

He has a thousand years to reflect on the effects which sin has wrought, to behold the results of his rebellion, and to look forward with dread to the time when he will be punished for the evil he has done and the sins he has caused others to commit. At the end of the thousand years (commonly known as the “millennium”) he will be “loosed” for a short time.

The saved are with Jesus in Heaven for a thousand years where the records of all are reviewed and the judgements are verified.

At the end of the millenium the New Jerusalem will descend to the earth with the saints inside and the city will replace what was previously but down destroyed earthy Jerusalem.

Once the final court case is over and all agree on the verdict of the dead who choose self over God, the New Jerusalem descends to earth then comes the Second Resurrection.

After the 1000 years, the wicked are raised but are not given glorified bodies. This means they are raised in the same condition as their death.

All the wicked who have ever lived are now resurrected in “the resurrection of damnation,” and satan is “loosed out of his prison.” After his long incarceration, he now has all his subjects, the vast multitude of the lost, to tempt, deceive and torment.

“Then Jesus and the holy angels, accompanied by all the saints, again go to the city, and the bitter lamentations and wailings of the doomed wicked fill the air. Then I saw that satan again commenced his work. He passed around among his subjects, and made the weak and feeble strong, and told them that he and his angels were powerful. He pointed to the countless millions who had been raised. There were mighty warriors and kings who were well skilled in battle and who had conquered kingdoms. And there were mighty giants and valiant men who had never lost a battle. There was the proud, ambitious Napoleon, whose approach had caused kingdoms to tremble. There stood men of lofty stature and dignified bearing, who had fallen in battle while thirsting to conquer. As they come forth from their graves, they resume the current of their thoughts where it ceased in death. They possess the same desire to conquer which ruled when they fell. satan consults with his angels, and then with those kings and conquerors and mighty men. Then he looks over the vast army, and tells them that the company in the city is small and feeble, and that they can go up and take it, and cast out its inhabitants, and possess its riches and glory themselves. satan succeeds in deceiving them, and all immediately begin to prepare themselves for battle. There are many skillful men in that vast army, and they construct all kinds of implements of war. Then with satan at their head, the multitude move on. Kings and warriors follow close after satan, and the multitude follow after in companies. Each company has its leader, and order is observed as they march over the broken surface of the earth to the Holy City. Jesus closes the gates of the city, and this vast army surround it, and place themselves in battle array, expecting a fierce conflict. Jesus and all the angelic host and all the saints, with the glittering crowns upon their heads, ascend to the top of the wall of the city.” Early Writings (EW 293.1)

“Satan succeeds in deceiving them, and all immediately begin to prepare themselves for battle. There are many skillful men in that vast army, and they construct all kinds of implements of war. Then with Satan at their head, the multitude move on. Kings and warriors follow close after Satan, and the multitude follow after in companies. Each company has its leader, and order is observed as they march over the broken surface of the earth to the Holy City. Jesus closes the gates of the city, and this vast army surround it, and place themselves in battle array, expecting a fierce conflict. Jesus and all the angelic host and all the saints, with the glittering crowns upon their heads, ascend to the top of the wall of the city. Jesus speaks with majesty, saying, “Behold, ye sinners, the reward of the just! And behold, My redeemed, the reward of the wicked!” The vast multitude behold the glorious company on the walls of the city. And as they witness the splendor of their glittering crowns and see their faces radiant with glory, reflecting the image of Jesus, and then behold the unsurpassed glory and majesty of the King of kings and Lord of lords, their courage fails. A sense of the treasure and glory which they have lost rushes upon them, and they realize that the wages of sin is death. They see the holy, happy company whom they have despised, clothed with glory, honor, immortality, and eternal life, while they are outside the city with every mean and abominable thing.” Early Writings (EW 293.2)

Then the sentence is executed. “Fire” comes “down from God out of heaven” to devour the wicked, turning the earth’s surface into a vast “lake of fire.” It burns up “the devil,” “the beast,” “the false prophet” and “whosoever was not found written in the book of life,” vs. 15. Sin and the effects of sin are destroyed, including “death” and “hell” (the grave), vs. 14. In the cleansing flames the wicked are annihilated; this is the second death. “Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power,” vs. 6. The fire that consumed the wicked purifies the earth. Every trace of the curse of sin is swept away. The universe is once again free from sin and rebellion.

One could imagine that the love of God comes down as an embrace, a consuming fire, which hugs each of the fallen creation until they stop struggling and accept His love and then they are at peace and cease to exist.

A sense of the treasure and glory which they have lost rushes upon them, and they realize that the wages of sin is death. They see the holy, happy company whom they have despised, clothed with glory, honor, immortality, and eternal life, while they are outside the city with every mean and abominable thing.” satan rushes into the midst of his followers and tries to stir up the multitude to action. But fire from God out of heaven is rained upon them, and the great men, and mighty men, the noble, the poor and miserable, are all consumed together. I saw that some were quickly destroyed, while others suffered longer. They were punished according to the deeds done in the body. Some were many days consuming, and just as long as there was a portion of them unconsumed, all the sense of suffering remained. Said the angel, “The worm of life shall not die; their fire shall not be quenched as long as there is the least particle for it to prey upon.” satan and his angels suffered long. satan bore not only the weight and punishment of his own sins, but also of the sins of the redeemed host, which had been placed upon him; and he must also suffer for the ruin of souls which he had caused. Then I saw that satan and all the wicked host were consumed, and the justice of God was satisfied; and all the angelic host, and all the redeemed saints, with a loud voice said, “Amen!” Said the angel, “satan is the root, his children are the branches. They are now consumed root and branch. They have died an everlasting death. ” Early Writings (EW 294.1)

It is a "strange act" that God deletes the wicked.

We need only to stop choosing self and accept His gift of Righteousness and live! God wishes that all choose harmony and live!

But so many of God's creation are fighting against Him, embracing self and fighting against harmony. They have no rest day nor night, but God has called us all into His rest!
