Which line is from Milton's On His Blindness?

• A. They also serve who only stand and wait.
• B. To err is human, to forgive divine.
• C. The fault, dear Brutus, is not in our stars.
• D. All that glitters is not gold.

Answer: (A)

The line in question centers on the idea that service to God isn’t limited to active, visible deeds; it includes patient endurance in the face of hardship. In Milton’s On His Blindness, the speaker has lost sight and cannot perform the usual work he once did, yet he asserts that continuing to trust and wait—holding to faith despite the loss—still constitutes meaningful service. That message—dignity and usefulness found in quiet perseverance—is unique to this sonnet and reflects Milton’s meditation on how disability can be integrated into a life of faith.

The other famous lines come from different authors and contexts: one is a reflection on human fallibility and forgiveness, another questions fate and free will, and another warns against judging by appearances.
