Answer + Explanation:
1. A Dam on a Flooded River (Metaphor)
One of the more striking metaphors for God’s wrath, which is so often likened to a raging fire, is that of a powerful river held back by a dam. What’s so effective about this image is that, paradoxically, God is both the raging, powerful waters, and the dam that holds them back from sweeping away and drowning those who are living in sin. And the implication is that, like a river that has been unnaturally obstructed, God’s wrath only increases in tension and power the longer it is held back.
2. Edwards also uses a metaphor to express how even powerful rulers are nothing but feeble worms in comparison with God (“...the greatest earthly potentates in their greatest majesty and strength...are but feeble, despicable worms of the dust, in comparison of the great and almighty Creator and King of heaven…”).
3. Jonathan Edwards uses the emotional appeal of fear to persuade his audience that they should turn to God. A first way he does this is through the image of hell. He does this in a metaphor that suggests he** is a burning pit of fire that God holds his people over and is ready to drop them at any moment:
   O sinner! Consider the fearful danger you are in: it is a great furnace of wrath, a wide and bottomless pit, full of the fire of wrath, that you are held over in the hand of that God, whose wrath is provoked and incensed as much against you, as against many of the da**ed in he**.
You can see this is also a metaphor of heII to mean a furnace... it must be hot.

I hope this helped in you in any or some way. If not, I apologize.
