Final answer:
John Winthrop promised that the Puritans would become like a shining city on a hill if they lived up to their spiritual and communal obligations.
Step-by-step explanation:
John Winthrop promised that if the Puritans live up to their part of the covenant with God, they would become like a shining city on a hill. This vision was eloquently stated in his sermon “A Model of Christian Charity” where Winthrop expressed his hope that the Puritan community in the Americas would embody the ideal Christian community. The concept of the covenant for the Puritans linked their social and civil bonds to God, desiring to construct a society that would serve as a moral exemplar to the world, aligning with their belief in living with piety and virtue.
