Barrett Browning was heavily influenced by her husband Robert Browning.
Love is mixed with religious imagery.
Starts with a rhetorical question, directly addresses the reader.
Her love is far reaching in 'depth' 'height'.
'Soul' suggests a spiritual love and gaining a sense of 'being' through her love.
She loves him 'freely' suggests she wants nothing in return.
Plosive alliteration 'passion put to use' and 'purely' and 'praise'.
Repetition of 'I love thee' emphasises her love and suggests it has several dimensions.
As a child she had religious faith and she loves him this purely.
The love spans across her life and into her death.
'And if God choose, I shall but love thee better after death.'
Religious overtone to the poem. Is her love for God? or for a male?
Could compare it to: Sonnet 166, In Paris With You, To His Coy Mistress.
