The Surgeon Who Believed in What He Couldn't See

In 1865, nearly half of all amputation patients at Glasgow Royal Infirmary died from infection. Surgeons operated with unwashed hands, wearing blood-crusted coats they considered badges of experience. Then Dr. Joseph Lister did something his colleagues called absurd — he began sterilizing wounds and instruments with carbolic acid, insisting that invisible organisms were killing his patients.

The other surgeons laughed. You couldn't see germs. You couldn't measure them with the instruments of the day. Lister was asking the medical establishment to stake lives on something unseen.

But his patients lived. Ward after ward, infection rates plummeted. The evidence of the invisible was written in the survival of the people who trusted him.

Hebrews 11:1 tells us that faith is "the substance of things hoped for, the evidence of things not seen." Like Lister's colleagues, we sometimes struggle to trust what we cannot see or touch. We want proof before we step forward. But faith has never required the absence of evidence — it requires a different kind of seeing.

Lister's patients didn't need to understand microbiology. They needed to trust the surgeon who did. And we don't need to comprehend every mystery of God's plan. We need to trust the One who holds it.

Sometimes the most life-saving thing you can do is believe in what you cannot yet see.
