The poem "The Chimney Sweeper" is set against the dark background of child labour that was prominent in England in the late 18th and 19th centuries.
In the earlier poem, a young chimney sweeper recounts a dream by one of his fellows, in which an angel rescues the boys from coffins and takes them to a sunny meadow; in the later poem, an apparently adult speaker encounters a child chimney sweeper abandoned in the snow while his parents are at church or possibly even suffered death where church is referring to being with God.

[4] In 'The Chimney Sweeper' of Innocence, Blake can be interpreted to criticise the view of the Church that through work and hardship, reward in the next life would be attained; this results in an acceptance of exploitation observed in the closing lines 'if all do their duty they need not fear harm.'
Blake uses this poem to highlight the dangers of an innocent, naive view, demonstrating how this allows the societal abuse of child labor.
