I think Finrod Felagund paid dearly - he took the worst for Beren!
His statement seemed to say that he was going to do his best for the future, despite being under the curse. Not many of the accursed could say that.
I believe that due to his sacrifice he's be dealt with in a more merciful nature, certainly.
Does this equate with Christian beliefs? Yep. But I think it's really just a moral thing. Do the right thing! Don't get all sour like the rest of one's family and sit around waiting for the end to come, or run into death on the wrong side of the fence.
I love a hero, especially one that remembers his promises. Finrod earned my "favorite Elves" award right along with Beleg Strongbow, (and we all know he didn't leave Turin in the mud just because Thingol told him he was a high risk dude.)
Unfortunately, though, Tolkien doesn't remark about Finrod's ultimate fate.
It seems to us that Finrod made his sacrifice with the full knowledge that he might not be forgiven, and that makes his death much more meaningful.
Don't cha think?
