Why were God and the Sears Roebuck catalogue linked in Jeanne's mind in Farewell To Manzanar?

It doesn't really seem like God and the Sears catalog
ought to be linked in someone's mind, but they were for Jenne during her time at
Manzanar.

The reason why they were linked is that both of
them represented things that could not be gotten there at the camp.  Both God and the
Sears catalog represented good stuff, stuff that they were not able to easily get while
in the camp.

Jeanne even starts sort of confusing the two. 
She prays for dried apricots, but she fantasizes that they will come in a package from
Sears.
