Final answer:
Jonathan Edwards did not mistake religious feelings and actions for God's grace but rather used reason to convey his sermons, which nonetheless evoked strong emotional reactions in his listeners.
Step-by-step explanation:
It is false that Jonathan Edwards mistook religious feelings and actions for God's grace in his life. Unlike his contemporary George Whitefield, whose preaching style was more emotive, Edwards's approach was more restrained. He reached his listeners primarily through reason, though his sermons 'Sinners in the Hands of an Angry God' often had a profoundly emotional effect, causing reactions such as weeping and fainting, bearing witness to the impact they had on the audience. In the context of the Great Awakening, Edwards emphasized the individual's relationship with God and took part in the spread of new evangelical Protestant denominations due to the religious revival. As a result, church attendance and conversions surged in New England.
