Answer Details

The extra detail that Mark gave in his account of the stilling of the storm, not contained in either Matthew or Luke, is that Jesus was in the stern, asleep on a cushion. This detail highlights the humanity of Jesus, who was exhausted from his ministry and able to rest even in the midst of a raging storm. It also emphasizes the power of Jesus, who was able to calm the storm with just a word, despite being asleep when the disciples woke him up. This detail adds to the dramatic effect of the story and underscores the faith of the disciples in Jesus as they marveled at His power.
