The Surgery Before the Healing

In wound care, surgeons practice a procedure called debridement — the careful removal of dead, damaged, or infected tissue from a wound. It seems counterintuitive. A patient arrives with an open wound, and the surgeon makes it larger. But every wound care specialist understands the principle: necrotic tissue left in a wound does not simply fail to heal — it actively prevents healing. It harbors bacteria, blocks blood flow to healthy cells, and traps the body in a cycle of inflammation that cannot resolve on its own.

Forgiveness works the same way in the human soul.

When someone wounds us deeply, our instinct is to protect the injury — to wall it off and leave it untouched. But unforgiveness is necrotic tissue. It does not sit quietly. Dr. Karen Swartz, a psychiatrist at Johns Hopkins, has documented that holding onto resentment chronically elevates cortisol, raises blood pressure, and weakens the immune system. The wound you refuse to clean becomes the wound that slowly poisons the rest of your body.

God does not ask us to forgive because the offense was small. He asks because He refuses to let dead things occupy the space where new life belongs. "If anyone is in Christ, the new creation has come: the old has gone, the new is here" (2 Corinthians 5:17).

Forgiveness is the debridement of the soul — painful, necessary, and the only path to true healing.
