Question

which quotation from \sinners in the hands of an angry god\ indicates that people have a fragile hold on life?
○ yea, god is a great deal more angry with great numbers that are now on earth; yea, doubtless with many that are now in this congregation . . . than he is with many of those that are now in the flames of hell.
○ 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.
○ unconverted men walk over the pit of hell on a rotten covering, and there are innumerable places in this covering so weak that they wont bear their weight, and these places are not seen.
○ god is dreadfully provoked, his anger is as great towards them as to those that are actually suffering the executions of the fierceness of his wrath in hell.

Explanation:

The question asks for a quote that illustrates people's fragile hold on life. The third quote uses the metaphor of unconverted men walking over hell on a rotten, weak covering with unseen fragile spots—this directly symbolizes how precarious and fragile human life/avoidance of damnation is. The other quotes focus on God's anger or the readiness of hell, not the fragility of human life's hold.

Answer:

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