Final answer:
The statement regarding Jonathan Edwards' convictions and affections wearing off is false. Edwards was a central figure in the Great Awakening with his powerful and reasoned sermons continuing to inspire and emotionally affect many, leading to increased conversions and sustained religious enthusiasm.
Step-by-step explanation:
Based on the historical context provided, the statement 'After a while, Edwards' religious convictions and affections wore off' appears to be false. Jonathan Edwards was a key figure in the Great Awakening in the Colonies, notably in New England. His preaching, primarily through logical and reasoned sermons, had a powerful and emotional impact on his audiences, as evidenced by the reactions to his famous sermon Sinners in the Hands of an Angry God. There is no indication that Edwards' religious convictions and the fervor that ensued during these revivals diminished over time. In fact, the increased conversions and church attendance suggest a sustained, if not growing, religious fervor influenced by Edwards' teachings and sermons.
