Eliyahu's conditions of survival in the widow's home are not a solution, in the context of the broader story, but rather an obstacle to the flow and progression of the narrative. A crisis will have to occur to interrupt Eliyahu's continued peaceful stay. The death of the widow’s son will lead to Eliyahu's banishment from her house.
