The following is an excerpt from the work of Dr. C. Truman Davis, MD.
As Jesus slowly sagged down with more weight on the nails in the wrist, excruciating, fiery pain shot along the fingers and up the arms to explode in the brain. The nails in the wrists were putting pressure on the median nerve, large nerve trunks which traverse the mid-wrist and hand. As He pushed himself upward to avoid this stretching torment, He placed His full weight on the nail through His feet. Again there was searing agony as the nail tore through the nerves between the metatarsal bones of his feet.
At this point, another phenomenon occurred. As the arms fatigued, great waves of cramps swept over the muscles, knotting them in deep relentless, throbbing pain. With these cramps came the inability to push Himself upward. Hanging by the arm, the pectoral muscles, the large muscles of the chest, were paralyzed and the intercostal muscles, the small muscles between the ribs, were unable to act. Air could be drawn into the lungs, but could not be exhaled. Jesus fought to raise Himself in order to get even one short breath. Finally, the carbon dioxide level increased in the lungs and in the blood stream, and the cramps partially subsided.
The Last Words
Spasmodically, He was able to push Himself upward to exhale and bring in life-giving oxygen. It was undoubtedly during these periods that He uttered the seven short sentences that are recorded.
The first – looking down at the Roman soldiers throwing dice for His seamless garment: “Father, forgive them for they do not know what they do.”
The second – to the penitent thief: “Today, thou shalt be with me in Paradise.”
The third – looking down at Mary His mother, He said: “Woman, behold your son.” Then turning to the terrified, grief-stricken adolescent John, the beloved apostle, He said: “Behold your mother.”
The fourth cry is from the beginning of Psalm 22: “My God, My God, why have You forsaken Me?”
He suffered hours of limitless pain, cycles of twisting, joint-rending cramps, intermittent partial asphyxiation, and searing pain as tissue was torn from His lacerated back from His movement up and down against the rough timbers of the cross. Then another agony began: a deep crushing pain in the chest as the pericardium, the sac surrounding the heart, slowly filled with serum and began to compress the heart.
The prophecy in Psalm 22:14 was being fulfilled: “I am poured out like water, and all my bones are out of joint, my heart is like wax; it is melted in the midst of my bowels.”
The end was rapidly approaching. The loss of tissue fluids had reached a critical level; the compressed heart was struggling to pump heavy, thick, sluggish blood to the tissues, and the tortured lungs were making a frantic effort to inhale small gulps of air. The markedly dehydrated tissues sent their flood of stimuli to the brain. Jesus gasped His fifth cry: “I thirst.” Again we read in the prophetic psalm: “My strength is dried up like a potsherd; my tongue cleaveth to my jaws; and thou has brought me into the dust of death” (Psalm 22:15 KJV).
A sponge soaked in posca, the cheap, sour wine that was the staple drink of the Roman legionnaires, was lifted to Jesus’ lips. His body was now in extremis, and He could feel the chill of death creeping through His tissues. This realization brought forth His sixth word, possibly little more than a tortured whisper: “It is finished.” His mission of atonement had completed. Finally, He could allow His body to die. With one last surge of strength, He once again pressed His torn feet against the nail, straightened His legs, took a deeper breath, and uttered His seventh and last cry: “Father, into Your hands I commit My spirit.”
