Communion this past Sabbath

This past Sabbath we celebrated Communion. Communion points back to the garden where man had sinless communion with God. When Adam ate from the forbidden tree, Adam and Eve were thrown out of the garden and unable to eat of that wonderful tree that Adam and Eve had been able to eat from before. Now all of mankind is doomed! For when Adam sinned, we all sinned in him since he was our covenant representative. At this point in the story, is there any hope at all?
