AtD: Lew's experience of grace

[Kai Frederik Lorentzen]

We know the novel ends with the word "grace", thereby giving it, the 
word, a special meaning.
All theological discussions aside for the moment, let me ask how "grace" 
is defined inside the
novel itself. I do so, because very early on, as I now realize during my 
regular re-read, an
important character, Lew Basnight, has his personal experience of 
"grace" which is, if I
didn't miss anything, the first concept of the term the novel has to 
offer us.

"One mild and ordinary work-morning in Chicago, Lew happened to find 
himself on a public
conveyance, head and eyes inclined nowhere in particular ["soft eyes", 
as they call it in The
Wire.kfl], when he entered, all too briefly, a condition he had no 
memory of having sought
[As A.C. has it: "Don't lust after results!".kfl], which he later came 
to think of as grace. (...)
Lew found himself surrounded by a luminosity new to him, not even 
observed in dreams,
nor easily attributed to the smoke-inflected sun beginning to light 
Chicago." (p. 42)

How representative is Lew's experience for AtD's overall concept of "grace"?
