Identify the three famous figures of speech that Edwards develops in the the fourth through seventh paragraphs. What things is he comparing?

Three famous
images from this section of "" are as follows:

Slippery ground: Edwards alludes to the Bible when he says
people walk on slippery ground. The material world we depend on can fail us at any timewe are
only kept from slipping and falling down by the will of God, and God has no reason, beyond his
own desire, to keep us from falling. If we do slip and fall, we will slide in the pit of
hell:

he that stands on such slippery declining ground, on
the edge of a pit, he cannot stand alone, when he is let go he immediately falls and is
lost.

Fires of hell: Perhaps
the most famousin the sermon is that describing hell. The hellfires are ready to burn us and
consume us if we fall:

the pit is prepared, the fire is
made ready, the furnace is now hot, ready to receive them; the flames do now rage and
glow.

The rotten bridge:
Life is like walking over a rotten bridge. At any moment, we might fall through it into the
flames of helland we can't even see where we are going. As Edwards puts it,

men walk over the pit of hell on a rotten covering, and there are
innumerable places in this covering so weak that they will not bear their weight, and these
places are not seen.

These vivid visual and spatial
images emphasize how close hell is to ordinary people and how terrifying it is. Edwards used
these images to encourage people to seek a proper relationship with God
immediately.
