In the quote from Mark Helprin's "A Soldier of the Great War," the importance of belief is emphasized as a vital part of living fully. It encourages readers to believe not just for themselves, but for others who may have lost hope. The idea is that holding onto belief can be a source of strength and resilience, contributing to one's own vitality and sense of purpose.
Helprin urges us to persist through doubt and despair, suggesting that mystery and uncertainty should not lead us to abandon our faith. Instead, we are reminded to embrace belief as a powerful force that can inspire love and keep our hearts vibrant. This message highlights the significance of maintaining hope, even in challenging times.
