What do you think of the use of fear as a motivator in "Sinners in the Hands of an Angry God"? What motivation might work better than fear?

Fear is the
ultimate motivator. If you look at history, or even current events, fear gets us to act. Take a
look at how travel has changed within the United States because of terrorism. We fear what could
happen on a plane and therefore, millions of travelers daily go through a routine that adds an
extra 5-60 minutes to their travel plans. These aren't minutes spent for fun, they are spent in
response to fear.

I agree that it is not right to motivate religiously out
of fear, however, according to Christian theology hell is very real. If you read the bible,
God's wrath and grace come across...
