Final answer:
The claim that Jonathan Edwards led an immoral life after believing in God's sovereignty is false. Edwards was a renowned preacher known for his morally rigid stance and evoking religious fear through his sermons. Predestination doctrine holds that salvation is predetermined, which is true.
Step-by-step explanation:
Regarding the student's question on whether it is true that after Edwards believed in God's sovereignty, he led an immoral life, the answer is False. Jonathan Edwards was a prominent preacher and theologian in colonial America and is best known for his fiery sermons and advocacy for a deeply emotional form of Christianity during the First Great Awakening. His most famous sermon, "Sinners in the Hands of an Angry God," aimed to instill a fear of sin and an appreciation for God's power. Rather than leading an immoral life, Edwards promoted moral living and a profound respect for divine authority.
It is also important to address the related concept of predestination. The student asks about the doctrine of predestination which asserts that a person's fate of salvation is predetermined. The statement, "According to the doctrine of predestination, a person was either saved from the time of his birth" is True. This doctrine was central to the beliefs of many Puritans during Edwards' time, who felt that their outcomes were preordained by God's will regardless of their actions on Earth.
