"'The good shepherd lays down his life for the sheep' (John 10:11). While Jesus was saying these words, the Apostles did not realize that he was referring to himself. Not even his beloved Apostle John knew it. He understood on Calvary, at the foot of the Cross, when he saw Jesus silently giving up his life for 'his sheep.' When the time came for John and the other Apostles to assume this same mission, they then remembered his words. They realized that they would be able to fulfill their mission only because he had assured them that he himself would be working among them."
