Joy is so natural to Christian healing that the disciples of Christ Jesus could "rejoice with joy unspeakable and full of glory," I Pet. 1:8. even when Jesus was no longer personally with them.
Yet there was a time when they did not feel that joy. They were discouraged. Their great Teacher had been crucified. A few of them had gone back to their old occupation of fishing, only to find there was no joy there. They labored all night but caught nothing.
Then something happened that would change their standpoint, that would restore their courage and establish their joy on a more lasting basis. Jesus appeared on the shore. There he stood, the victor over injustice, hatred, and every aggressive evil that claimed to have conquered him and destroyed his work. They soon recognized the risen Saviour, and realized that he had not only defeated death, but had put an exclamation point of certainty after everything he had taught and shown them. He had proved that however dire the claims of evil, material conditions do not have dominion over man. Jesus told his followers how to fight and win the battle themselves, and what he said was so simple: "Cast the net on the right side of the ship, and ye shall find." John 21:6.
