Now that he has established why so many are damned and what horrors await them... it is time for redemption. A fitting portion to any sermon, a chance to be saved and if you pass today. "remarkable vengeance to others..." This leaves a powerful psychological impression on the crowd to walk out on. It fills the individuals with thoughts and second guesses, "I thought I was devout and saved... but is this my day of vengeance?". I would be very curious to see what the crowd looked like on exiting, how many were tearful with shame vs holding their head high with the belief the sermon was about all those other sinners...
