According to the Gospels, one evening Jesus and his disciples were crossing the Sea of Galilee in a boat. Suddenly a furious storm came up, with the waves breaking over the boat so that it was nearly swamped. Jesus was asleep on a cushion in the stern, and the disciples woke him and asked, "Teacher, don't you care if we drown?" The Gospel of Mark then states that:
He woke up and rebuked the wind, and said to the sea, "Peace! Be still!" Then the wind ceased, and there was a dead calm. He said to them, "Why are you afraid? Have you still no faith?" And they were filled with great awe and said to one another, "Who then is this, that even the wind and the sea obey him?"
It has always been a popular subject for Christian painters and here are a few examples.
