Why did Frodo Volunteer to take the Ring?

[The Saucepan Man]

Frodo knew it was his duty to take the ring as soon as Gandalf explained the history of the ring and what must happen to it.

Thank you Moonpie for demystifying for me what seems to have become a very complicated debate about Frodo's motives and who, or what, may have influenced him in his decision.

I agree. I have always been very much inclined to the view that, at that moment at the Council of Elrond, Frodo knew, in his heart of hearts, that he was the one to undertake this Quest. It could be no other, and he knew that.

Frodo assumes the task willimgly and knowing that it is his to perform. Had he not done so, then I daresay that he would have succumbed to the power of the Ring much earlier than he did.
