Why did Frodo Volunteer to take the Ring?

[HerenIstarion]

And so does another thread fall into the black hole of Fate vs Free Will

And so does H-I poke with a shovel and pull out the grubby remnants of it back to the light, as is his wont for threads about Fate and Free Will

But the matters which I would have brought to attention here (as Fate and Free Will are much discussed already in manifold threads all around the place) is trust

I intended to start a separate thread for it, but Frodo looked as a good example, so I simply brought current one back

I had no time back than to develop the theme, (neither do I have much of it now), but I would you focus on the passage in Finrod/Andreth discussion running as follows:

What is hope?' she said. 'An expectation of good, which though ncertain has some foundation in what is known? Then we have none.'

'That is one thing that Men call "hope",' said Finrod. 'Amdir we call it, "looking up". But there is another which is founded deeper. Estel we call it, that is "trust". It is not defeated by the ways of the world, for it does not come from experience, but from our nature and first being. If we are indeed the Eruhin, the Children of the One, then He will not suffer Himself to be
deprived of His own, not by any Enemy, not even by ourselves.
This is the last foundation of Estel, which we keep even when
we contemplate the End: of all His designs the issue must be for
His Children's joy.

To the best of my knowledge, that is backbone of Tolkien. (So the trust of those holding on to Estel is usually justified)

Now, I will refrain from coming up with said paragons. I expect the future contributors to the thread to come up with some It would be good check for me to find if what I see there is seen by many (and I do hope there are many)

It would be good also to take a look at this and this, though said threads do not directly deal with what I try to bring to attention here
