What were the signs in John's Gospel pointing to for the nation of Israel?

Les explains that the sign miracles in John's Gospel were not isolated wonders; they were all indicative of God doing something for the nation of Israel. The eighth sign took place after Christ's resurrection. The disciples were up on the Sea of Galilee, fishing all night and catching nothing. The Lord stood on the shore in the morning, asked if they had any food, and they said no. He told them to cast the net on the right side of the ship. They did, and they could not draw it for the multitude of fishes. Peter drew the net to land, full of 153 great fishes, yet the net was not broken. Les notes that the last time Jesus told them to cast on another side, the net broke; here it did not. That unbroken net with 153 great fishes is the real sign of this miracle.
