The Boy Who Walked Out of the Ward

In January 1922, fourteen-year-old Leonard Thompson lay dying in Toronto General Hospital. Type 1 diabetes had wasted his body to sixty-five pounds. Before that winter, the diagnosis meant one thing: a slow, irreversible decline. There was no treatment, no hope — only the careful rationing of days.

Then Frederick Banting and Charles Best injected Leonard with a purified extract from a bovine pancreas — insulin. Within days, his blood sugar normalized. His strength returned. He gained weight. He walked out of that hospital ward a boy given back his life.

What strikes me about Leonard's story is not just the cure but the captivity that preceded it. His own body had become his prison. The very organ designed to regulate his life had failed, and no amount of willpower or discipline could compensate. He needed something from outside himself.

Paul understood this kind of captivity. "What a wretched man I am!" he wrote. "Who will rescue me from this body that is subject to death?" (Romans 7:24). Like Leonard's failing pancreas, our spiritual machinery is broken. Sin is not merely a series of bad choices — it is a systemic failure we cannot correct on our own.

But then Paul answers his own cry: "Thanks be to God, who delivers me through Jesus Christ our Lord!" (Romans 7:25).

The gospel is our insulin. It does not ask us to heal ourselves. It enters the bloodstream of our lives and does what we never could. That is freedom — not the absence of disease, but the presence of a remedy we did not earn and cannot exhaust.
