[stripes1776]

Frodo takes the Ring (the sins of the world) onto himself and suffers and sacrifices all that he loves for the world.

Frodo does suffer a great deal to return the ring into the fire from which it came. But when that moment comes, he desires to keep the ring for himself. His friend Sam steps forth to throw the ring into the fire. Sam was there to serve and protect Frodo. But he didn't carry the weight or the temptation of the ring. Frodo did that for him. And at last Sam overcomes his fear and must throw the ring in the fire for Frodo who has succumbed to temptation after all his efforts to resist it.

And at last Sam overcomes his fear and must throw the ring in the fire for Frodo who has succumbed to temptation after all his efforts to resist it.

No, that isn't correct. My memory failed me. It is Gollum who falls into the fire after biting off Frodo's finger with the ring still on it.
