In John 6, Jesus told the disciples to go out ahead of him across the lake into the storm (tribulation). Then He came to them after they had gone 25 or 30 furlongs (6:19), which was the middle of the lake. When Jesus got into the boat, the entire boat was transported to Capernaum (6:21, 24). Capernaum means "the Covering of the Comforter." It speaks of the fullness of the Spirit.
