The title of the movie is taken from George Elliot. In Middlemarch she writes:
"The growing good of the world is partly dependent on
unhistoric acts; and that things are not so ill with you and me as they might
have been, is half owing to the number who lived faithfully a hidden life, and rest in unvisited
tombs."
Though Evans (Elliot) was an infidel, the quote as it stands
is true and worthy of reflection. We might modify it a bit and rather than
think in terms of the 'growing good of the world', instead we can ponder the
testimony that will be revealed in heaven itself. Hebrews 11 tells us that the
'winners' in terms of the Kingdom are those who wandered about destitute,
living in caves and other lonely places, suffering torture and even death. In
the world's eyes they were losers but as Christians we don't see these things
or reckon them as the world does.
