Have ye then no hope?

[HerenIstarion]

Eru remains dominant & in theory must win out in the end

It seems there is a bit of more sadness for the elves (as Tolkien is picturing the World before Christ). Their Estel is more groundless - they may be sure (in fact, they are sure) that Eru will win in the end, but they are not sure what will happen to themselves. They simply do not know what is beyond the world, in which they are destined to live as long it lasts, but beyond that? The Estel of the elves resides in hope (without evidence), that when Eru wins, he does not eliminate them - i.e. that they are not created to merely die out in the end. But they have no knowedge

I believe, to give their Estel a little bit of ground, not to confirm them as being beyond salvation (as they are picutred as good pagans) the whole of Athrabeth Finrod Ah Andreth was written.

As opposed to, say, men of the 7th age, which have Gospels - literally translated as "Good Tidings".
