According to Edwards, in "Sinners in the Hands of An Angry God", there are many constant threats to mankind.
Basically, as shown in the verse preceding the sermon (Deut. 32:35) mankind was simply facing the fact that "In due time their foot would slip."
That being said, there were multiple things that Edwards was stating existed as constant threats to humanity.
Death is always at hand.
While Edwards states that God can at any time withdraw his hand and allow man to fall into the pit of hell, the fact remains that to fall into the pit of hell one must die first.
That being said, it is not necessarily only the fact that God can, at any time, choose to send a man/woman to hell, it is the ever-present fear of death.
