Where It Really Hurts

In emergency medicine, doctors learn early about a phenomenon called referred pain. A patient rushes in clutching their left arm or rubbing their jaw, certain something is wrong there. But the real crisis is in their chest — a heart attack sending distress signals along shared nerve pathways to distant parts of the body. The pain is genuine, but its source is somewhere else entirely.

The neurologist Sir Henry Head mapped this phenomenon over a century ago, charting how internal organs project pain onto the skin's surface. Treat the arm, and you've done nothing. Find the heart, and everything changes.

Unforgiveness works the same way. We feel the ache in our relationships — the tension at family gatherings, the coldness toward a former friend, the flash of anger when a name is mentioned. We assume the problem is out there, with the person who wronged us. If only they would apologize. If only they would change. If only they hadn't done what they did.

But the damage is happening inside us. The bitterness, the replayed conversations, the rehearsed grievances — these are the real injury, and no amount of treating the symptoms will reach it.

Forgiveness is the moment we stop rubbing the arm and let the Great Physician reach the heart. As Paul wrote, "Get rid of all bitterness, rage and anger" — not because the offender deserves it, but because your heart cannot heal while it is still under siege.
