Answer 2

Edwards listeners mistakenly believe that their behaviour description keeps them from falling into Hell.  

Explanation:

Edwards describes the miserable and terrifying description of hell and says that people would be going around seeing who did not attended the church, and if they were not in church, they would not hesitate to put their name in a book and this would come back to them.

He is trying his audience to get them afraid enough of miserable Hell that they will eventually change their ways of living.

Edward states that death has always been at hand and those people must depend on God and repent always.
