Answer: The last two lines from Sonnet 130 tell us that the speaker accepts his mistress despite her supposed flaws.
Step-by-step explanation:
Shakespeare's Sonnet 130 is a humorous response to Petrarchan conventions of love poetry.
The speaker makes a number of comparisons between his loved one and different things, but tells us that she has nothing in common with them. Her eyes are ''nothing like the sun'', music is much more pleasing than the sound of her voice, unlike a goddess, his mistress walks on the ground, etc. However, the tone changes in the last two lines:
And yet by heaven, I think my love as rare,
As any she belied with false compare.
At the end of the poem, he admits that his love for her is as strong as love of other poets who flatter their mistresses with false comparisons. Although he does not over-exaggerate in describing her beauty, it does not mean that his love is not strong enough.
