Fay,

Yes, I agree with you, about nations and Israel.

So, in addition to the judgment of our sins upon the cross;

And in addition to the judgment seat of Christ for the believers;

As well as the great white throne judgment for the lost;

There must needs be a judgment of the nations, as nations, for justice and righteousness sake;

Particularly how those nations have treated the nation of Israel.

Matthew 25:31 When the Son of man shall come in his glory, and all the holy angels with him, then shall he sit upon the throne of his glory:

  32 And before him shall be gathered all nations: and he shall separate them one from another, as a shepherd divideth his sheep from the goats:

The judgment of the sheep nations and the goat nations, by how they treated the LORD's chosen people.

It can't be simply the judgment of individuals, as that would have the lost judged twice for the same things (here & the white throne).

Also, if this is simply a judgment of individuals, then people get saved by how they treat the LORD's people, bypassing the cross.

No, there must be a judgment of nations, for justice, like there had to be the Nuremberg trials after the second world war.
