Final answer:
The lines from George Herbert's "The Pulley" suggest that Grace is God's mercy given undeservedly to mankind, a concept also found in the works of Phillis Wheatley and explored by Vincent Lloyd.
Step-by-step explanation:
George Herbert's poem "The Pulley" reflects the theological concept of Grace as God's mercy given to human beings, even though they do not deserve it. The poem illustrates that God's graciousness is evident in the way He deals with humanity, bestowing gifts and blessings, but withholding 'rest' so that humanity would ultimately depend on God, thereby recognizing the need for divine Grace. This concept is further exemplified in the works of Phillis Wheatley, who, in her poem "On Being Brought from Africa to America," acknowledges the mercy of being brought from a 'Pagan land' to learn about God and salvation, and how those who are scorned for their race can also be recipients of this redemptive grace. Similarly, Vincent Lloyd in 'The Problem with Grace' discusses the complexities surrounding the idea of Grace in a theological and philosophical context.
