And His sacrifice was a suffering sacrifice. Notice He says, “This is my body which was broken for you.” A medical doctor, Truman Davis, contemplated the cross to determine what it was that caused Christ to die. Here’s what he wrote about the suffering of Christ:
The preliminary scourging was done with the victim naked, his arms tied to a post above his head. The heavy whip is brought down with full force again and again across Jesus’ shoulders, back, and legs. At first the thongs cut through the skin only. Then, as the blows continue they cut deeper until the half-fainting victim is untied and allowed to slump to the pavement, wet in his own blood.
At the site of execution, the crossbeam is thrown down, and the victim is pushed to the ground, his arms stretching over the wood. The legionnaire feels for the depression at the front of the wrist. He drives a heavy, square, wrought-iron nail through the wrist and into the wood. Quickly, he moves to the other side. Jesus is hauled up and lifted onto the upright post.
The left foot is now pressed backward against the right foot, and with both feet extended, toes down, a nail is driven through the arch of each, leaving the knees moderately flexed. The victim is now crucified. As he slowly sags down with more weight on the nails in the wrists excruciating pain shoots along the fingers and up the arms to explode in the brain—the nails in the wrists are putting pressure on the median nerves. As he pushes himself upward to avoid this stretching torment, he places his full weight on the nail through his feet. Again there is the searing agony of the nail tearing through the nerves between the metatarsal bones of the feet.
At this point, as the arms fatigue, great waves of cramps sweep over the muscles, knotting them in deep, relentless, throbbing pain. With these cramps comes the inability to push himself upward. In this position, air can be drawn into the lungs, but cannot be exhaled. The victim fights to raise himself up in order to get even one short breath. Finally carbon dioxide builds up in the lungs and in the blood stream and the cramps partially subside. Spasmodically, he is able to push himself upward to exhale and bring in the life-giving oxygen. It was undoubtedly during these periods that Jesus uttered the seven short sentences recorded.
The common method of ending a crucifixion was by the breaking of the bones of the legs. This prevented the victim from pushing himself upward; thus the tension could not be relieved from the muscles of the chest and rapid suffocation occurred. This was unnecessary for Christ, who died after six hours of crucifixion.
Apparently to make doubly sure of death, the legionnaire drove his lance through the fifth interspace between the ribs, upward through the pericardium and into the heart. There was an escape of water fluid from the sac surrounding the heart, giving postmortem evidence that our Lord died not the usual crucifixion death by suffocation, but of heart failure due to shock and constriction of the heart by fluid in the pericardium. He spiritually and physically died of a broken heart!
That was the suffering of his sacrifice. And what was its significance? Its found in those last two words of that phrase in v 24. “This is my body which was broken (look) for you!” You are the reason He gave His life!
