Edwards uses "fire and water" to preach about the wrath of God.
Sinners in the Hands of an Angry God by Jonathan Edwards was lectured in 1741 in Enfield, Connecticut, it is a warning to “sinners” to perceive that they will be reckoned by God and that this judgment will be more dreadful and agonizing than they can grasp.
This is usual scare strategies and dread that Edwards uses to make his point, obviously this overstated, hyperbolic spotlight on the fierceness of God totally overlooks His different characteristics, for example, his affection, benevolence and empathy.
