Nebulous "It" and Absolutes

[Hookbill the Goomba]

Saucepan Man, the ring in the hands of a Dwarf may not have necessarily been a good thing. Reason not withstanding, Hobbits had an incredible resistance to the rings power, A Dwarf may have not had the will or strength to even take up the challenge, only one with the simplicity and innocence of a Hobbit could do the deed, but I think Frodo will have known that If he was to accomplish the deed he would have to sacrifice much.

The Message I think Tolkien wants us to read from this is, The Hobbits were not over occupied with war or the memory of war; battle and power was not impotent to them.

"Elves and Dragons! Cabbages and potatoes are better for you."

Gaffer Gamgee

This pretty much sums up the attitude of the Hobbits. Their innocence was what made them resilient to the ring, Eru knew this, and so you can trace the pattern all the way back to when Olorin was created, Perhaps Gandalf's purpose was to send Bilbo on this mission to the Lonely mountain and so find the ring on the way, thus entangling himself in all deeds concerning the ring.

In U-T it tells us of how Gandalf remembered Bilbo as a child;

"Somehow I had been attracted by Bilbo Long before, as a child, and a young Hobit: he had not quite come of age when I had last seen him. He had stayed in my mind ever since, with his eagerness and his bright eyes, and his love of tales, and his questions about the wide world outside the Shire. As soon as I entered the shire I had news of him. He was getting talked about, it seemed. Both his parents had died early for Shire-folk, at about 80; and he had never married. He was already grown a bit queer, they said, and went off for days by himself. He could even be seen talking to strangers, even Dwarves!
Gandalf, Unfinished Tales, the Quest of Erebor

It is my belief that Eru Purposed it that Gendalf should remember Bilbo and so send him on this task, because hobbits had such resilience to the ring, he knew the ring would be dropped by Gollum, so he guided Bilbo's hand to find it. Old Olorin then left Bilbo with the choice to give up the ring of his own free will or to keep it, or be it with a little encouragement.
