What is Hughes saying here about “salvation”?

Any discussion of salvation must also consider its opposite: loss or perdition. The undesirable alternative to finding absolution in the love of Christ is the relinquishing of one’s immortal soul to Satan.
In this story, Langston Hughes presents a narrator who reflects on a religious revival that his Aunt Reed is in the habit of attending. The narrator is a child who believes that his aunt has insights into the spiritual truths that should be revealed in this service. This boy, however, does not remotely experience the sort of religious transport to which his aunt is so deeply committed. This supposed failure leaves him with the question of whether the fault lies in himself or in the service itself. Rather than salvation, this boy experiences profound doubt. Attending services, Hughes reminds the reader, is no sort of ticket to salvation.
