Walking on water is one of the miracles that the Gospels attribute to Jesus. An account of the miracle appears in the Gospels of John (John 6:16-21), of Matthew an of Mark . According to the Biblical narrative, Jesus sent the disciples in a boat, ahead of him, to Bethsaida, but when they were half way across the lake, Jesus walked over the lake and met them. The narrative states that the disciples were scared at first, thinking it was a ghost, but when Jesus revealed himself and got into the boat, they calmed down. According to Matthew (but not Mark, Luke or John) Peter was also able to walk on water, following Jesus's example.
