I think there is a level... for those who die quickly, they will be as if they never were.
Obadiah 1:16 Just as you drank on my holy hill, so all the nations will drink continually; they will drink and drink and be as if they had never been.
For others, they will suffer a little while,
Psalms 37:10, 11, "For yet a little while and the wicked shall be no more; Indeed, you will look diligently for his place, but it shall be no more."
Isaiah 1:28
And the destruction of the transgressors and of the sinners shall be together, and they that forsake the Lordshall be
consumed.
Just as stubble flash burns, so will a lot of those who do end up in the eternal fires.
Malachi 4:1,3. "For behold the day is coming burning like and oven, and all the proud, yes allude wickedly shall be as stubble. And the day that is coming shall burn them up, says the Lord of hosts,that shall leave them neither root nor branch. . . You shall trample the wicked for they shall be ashes under the soles of your feet."
I believe that Satan will suffer the longest and will be the last to finally burn up, for he is able to walk in the midst of the fire, and yet be untouched, but in the end something starts burning him up from the inside and he is consumed from within and then He will be no more. I believe that something is the insane rage from within as he watches all his kingdoms and all his men wiped out.
Ezekiel 28:18
Thou hast defiled thy sanctuaries by the multitude of thine iniquities, by the iniquity of thy traffick; therefore will
I bring forth a fire from the midst of thee, it shall devour thee, and I will bring thee to ashes upon the earth in the sight of all them that behold thee.
Jude 7 makes this subject very plain. "As Sodom and Gomorrah and the cities around them in a similar manner, having given themselves over to sexually immorality and gone after strange flesh, are set forth as an example, suffering the vengeance of eternal fire." Sodom and Gomorrah are not burning today, yet the Bible says they suffered the vengeance of eternal fire. How can this be explained? It means that these cities were completely burned, until there was nothing left.
