What about what Lois says to Clark in NeverEnding Battle? Where she talks to about Superman not being able to be everywhere, but just that he exists to do what he can gives people hope... Let's see what the script says:

Quote
LOIS: No. Even Superman can't be everywhere at once.

Her words are eerie echoes of Luthor's, and Clark reacts to them.

CLARK: Then what good is he?

LOIS: What he can't do... it doesn't matter. It's the idea of Superman. Someone to believe in. Someone to build a few hopes around. Whatever he can do: it's enough. (beat) If I could only tell him that. (beat) I hope it's not too late.
Is this the type of thing you're looking for?
