Question

read the excerpt from \sinners in the hands of an angry god.\ you will know certainly that you must wear out long ages, millions of millions of ages, in wrestling and conflicting with this almighty merciless vengeance; and then when you have so done, when so many ages have actually been spent by you in this manner, you will know that all is but a point to what remains. so that your punishment will indeed be infinite. oh who can express what the state of a soul in such circumstances is! edwards uses the phrase \oh who can express what the state of a soul in such circumstances is!\ in order to
○ show what might happen if the reader disobeys edwards.
○ describe what endless suffering looks and feels like.
○ illustrate that this type of suffering is unimaginable.
○ prove that very few people have survived limitless suffering.

Explanation:

1. Analyze Option 1: The phrase is not about disobeying Edwards, so this is incorrect.
2. Analyze Option 2: The phrase implies that the suffering is too great to be described, not about describing its look/feel, so this is incorrect.
3. Analyze Option 3: The phrase "Oh who can express..." suggests that the suffering is so extreme that it's beyond imagination, which matches this option.
4. Analyze Option 4: The text doesn't discuss surviving suffering, so this is incorrect.

Answer:

C. illustrate that this type of suffering is unimaginable.
