The Catheter and the Courage to Go First

In 1929, a young German surgeon named Werner Forssmann was convinced that a thin tube could be guided through a vein and into the living human heart — a claim his superiors called suicidal. Every senior physician refused to support the experiment. So Forssmann did what no one expected. He anesthetized his own left arm, made an incision, and threaded a catheter sixty-five centimeters through his antecubital vein, then walked down a flight of stairs to the radiology department to confirm with an X-ray that the tip had reached his right atrium. He risked his own life because he believed the truth he carried could save others.

His colleagues called him reckless. The hospital dismissed him. It would take nearly three decades before the Nobel Committee vindicated his work in 1956, recognizing cardiac catheterization as one of the most important advances in modern medicine.

Courage rarely looks sensible in the moment. When Joshua stood at the edge of the Jordan, God did not part the waters first. The priests had to step in while the river was still rushing. Faith moves before the proof arrives.

Some of you are standing at an incision point right now — a hard conversation, a calling that makes no sense on paper, a step of obedience that nobody around you supports. Take heart. The God who holds your every heartbeat is already in the room you have not yet entered. Step forward. He is faithful.
