The priests and rulers were amazed to find that Christ was dead. Death by the cross was a lingering process; it was difficult to determine when life had ceased. It was an unheard-of thing for one to die within six hours of crucifixion. The priests wished to make sure of the death of Jesus, and at their suggestion a soldier thrust a spear into the Saviour’s side. From the wound thus made, there flowed two copious and distinct streams, one of blood, the other of water. This was noted by all the beholders, and John states the occurrence very definitely. He says, “One of the soldiers with a spear pierced His side, and forthwith came there out blood and water. And he that saw it bare record, and his record is true: and he knoweth that he saith true, that ye might believe. For these things were done, that the scripture should be fulfilled, A bone of Him shall not be broken. And again another scripture saith, They shall look on Him whom they pierced.” John 19:34-37.
After the resurrection the priests and rulers circulated the report that Christ did not die upon the cross, that He merely fainted, and was afterward revived. Another report affirmed that it was not a real body of flesh and bone, but the likeness of a body, that was laid in the tomb. The action of the Roman soldiers disproves these falsehoods. They broke not His legs, because He was already dead. To satisfy the priests, they pierced His side. Had not life been already extinct, this wound would have caused instant death.
But it was not the spear thrust, it was not the pain of the cross, that caused the death of Jesus. That cry, uttered “with a loud voice” (Matt. 27:50; Luke 23:46), at the moment of death, the stream of blood and water that flowed from His side, declared that He died of a broken heart. His heart was broken by mental anguish. He was slain by the sin of the world.
