The Hobbit: “Mithrandir, why the halfling?“

“Galadriel: Mithrandir, why the Halfling? Gandalf: Saruman believes it is only great power that can hold evil in check, but that is not what I have found. I have found it is the small everyday deeds of ordinary folk that keep the darkness at bay... simple acts of kindness and love. Why Bilbo Baggins? Perhaps it is because I am afraid, and he gives me courage.“
