Amputees often experience some sensation of a phantom limb. Somewhere, locked in their brains, a memory lingers of the nonexistent hand or leg. Invisible toes curl, imaginary hands grasp things, a "leg" feels so sturdy a patient may try to stand on it. For a few, the experience includes pain. Doctors watch helplessly, for the part of the body screaming for attention does not exist.

One such patient was my medical school administrator, Mr. Barwick, who had a serious and painful circulation problem in his leg but refused to allow the recommended amputation. As the pain grew worse, Barwick grew bitter. "I hate it! I hate It!" he would mutter about the leg. At last he relented and told the doctor, "I can't stand it anymore. I'm through with that leg. Take it off." Surgery was scheduled immediately.

Before the operation, however, Barwick asked the doctor, "What do you do with legs after they're removed?"

"We may take a biopsy or explore them a bit, but afterwards we incinerate them," the doctor replied.

Barwick proceeded with a bizarre request: "I would like you to preserve my leg in a pickling jar. I will install it on my mantle shelf. Then, as I sit in my armchair, I will taunt that leg, 'Hah! You can't hurt me anymore!'"

Ultimately, he got his wish. But the despised leg had the last laugh. Barwick suffered phantom limb pain of the worst degree. The wound healed, but he could feel the torturous pressure of the swelling as the muscles cramped, and he had no prospect of relief. He had hated the leg with such intensity that the pain had unaccountably lodged permanently in his brain.

To me, phantom limb pain provides wonderful insight into the phenomenon of false guilt. Christians can be obsessed by the memory of some sin committed years ago. It never leaves them, crippling their ministry, their devotional life, their relationships with others. They live in fear that someone will discover their past. They work overtime trying to prove to God they're truly repentant. They erect barriers against the enveloping, loving grace of God. Unless they experience the truth in (1 John 3:19-20) that "God is greater than our conscience," they become a pitiful as poor Mr. Barwick, shaking a fist in fury at the pickled leg on the mantle.
