When a train goes through a tunnel and it gets dark, you don’t throw away the ticket and jump off. You sit still and trust the engineer.

The image of a train entering a dark tunnel frames hardship as a temporary passage rather than a final destination. The “ticket” suggests a commitment already made—faith, purpose, or a life path—that shouldn’t be discarded in panic when circumstances suddenly feel frightening or opaque. “Trust the engineer” shifts attention from the traveler’s limited perspective to a guiding intelligence beyond their control (often read theologically as trust in God’s providence). The quote’s force lies in its practical counsel: remain steady, don’t make rash exits, and endure uncertainty with patience until clarity returns.
