In Matthew 5:22 Jesus says that anyone who calls another a fool will be in danger of Hell fire
Matthew 5:22 KJV
But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire.
and in the Revelation Chapter 20:14 it tells us that Death and Hell will be thrown into the lake of fire:
Revelation 20:14 KJV
And death and hell were cast into the lake of fire. This is the second death.
Also in the story about Lazarus and the rich man:
Luk 16:22 through 24 KJV
22 And it came to pass, that the beggar died, and was carried by the angels into Abraham's bosom: the rich man also died, and was buried;
23 And in hell he lift up his eyes, being in torments, and seeth Abraham afar off, and Lazarus in his bosom.
24 And he cried and said, Father Abraham, have mercy on me, and send Lazarus, that he may dip the tip of his finger in water, and cool my tongue; for I am tormented in this flame.
Apparently some go to Hell when they die and are tortured by the heat (fire) and at the Great White Throne judgment are then thrown into the lake of fire.
Revelation 20:15 KJV
And whosoever was not found written in the book of life was cast into the lake of fire.
Revelation chapter says nothing about either Satan, His minions being judged only thrown into the lake of fire.
It does say that the dead are judged but only for their works:
Rev 20:12 and 13 KJV
12 And I saw the dead, small and great, stand before God; and the books were opened: and another book was opened, which is the book of life: and the dead were judged out of those things which were written in the books, according to their works.
13 And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works.
Does it seem possible that unbelief is judged along with Satan and his minions at the Cross, and the Great White Throne judgment is for what wrongs they have done on Earth?
