This is from an article by Marilynne Robinson on what literature owes the Bible:
The great assumption of literary realism is that ordinary lives are invested with a kind of significance that justifies, or requires, its endless iterations of the commonplace, including, of course, crimes and passions and defeats, however minor these might seem in the world's eyes. This assumption is by no means inevitable. Most cultures have written about demigods and kings and heroes. Whatever the deeper reasons for the realist fascination with the ordinary, it is generous even when it is cruel, simply in the fact of looking as directly as it can at people as they are and insisting that insensitivity or banality matters. The Old Testament prophets did this, too.
.....
In its emphatic insistence that the burden of meaning is shared in every life, the Bible may only give expression to a truth most of us know intuitively. But as a literary heritage or memory it has strengthened the deepest impulse of our literature, and our civilization.
I wouldn't have known quite how to put that but I like it, and the whole piece - where this thought is enlarged upon - is well worth your time.
