How does Jonathan Edwards depict the powerlessness of people and the precariousness of their situation in "Sinners in the Hands of an Angry God"? He describes people as being in danger of facing a flood like the one God sent during Noah's time.

He describes people as being likely to be turned into a pillar of salt, as Lot's wife was, for their wicked and sinful ways.

He describes people as being pushed by God to the edge of a steep and dangerous cliff, below which are jagged rocks.

He describes people as being held over a lake of fire and brimstone by God, who may choose to drop them.

The answer is "He describes people as being held over a lake of fire and brimstone by God, who may choose to drop them."
