Understanding the presentation of love in Browning's 'Sonnet 43'

‘Sonnet 43’ is one of Barrett Browning’s 44 sonnets that she wrote for her (then) future husband - Robert Browning. The poem follows the conventions of a Petrarchan sonnet. The poem explores the transcendental and bountiful love the poet and her future husband share. Barrett Browning eloped with Robert Browning, and was disinherited by her father. Barrett Browning struggled with chronic illness, which may explain why the poem has spiritual/religious undertones.
