'And so, as Tiny Tim observed, God bless us, everyone!'
The final line of the novella. Dickens emphasises 'everyone' to show that everyone poor or rich deserves luck and happiness. Even Scrooge when he wasn't a changed man. The message of Dicken's book is that even Scrooge deserves God's blessings, and if he gets them, it might just do him, and everyone else a whole world of good.
