Blake's later writings show a renewed interest in Christianity, and although he radically reinterprets Christian morality in a way that embraces sensual pleasure, there is little of the emphasis on sexual libertarianism found in several of his early poems, and there is advocacy of "self-denial", though such abnegation must be inspired by love rather than through authoritarian compulsion. Berger (more so than Swinburne) is especially sensitive to a shift in sensibility between the early Blake and the later Blake. Berger believes the young Blake placed too much emphasis on following impulses, and that the older Blake had a better formed ideal of a true love that sacrifices self. Some celebration of mystical sensuality remains in the late poems (most notably in Blake's denial of the virginity of Jesus's mother). However, the late poems also place a greater emphasis on forgiveness, redemption, and emotional authenticity as a foundation for relationships.
