When storm arose on Sea of Galilee, it often came without warning. In Mark 4:35-41 and Matthew 8:23-27 there are Biblical Words of Comfort and Promises.
A little history on The Book "Gospel of Mark": The Gospel was written under sanction of Peter. He scarely refers to Old Testament and word law does not once occur. In some reference books it is stated that this Gospel was meant for for use amongst Gentiles. It was written about 30 years after death of Jesus Christ. It is history of war of Jesus against sin and evil in world during time that he dwelt as a Man among men.
Jesus Disciples went with HIM in taking a ship ride to other side of Sea of Galilee. Jesus goes below deck and goes to sleep. A Storm comes up right away and HIS Disciples were threatened. HIS Disciples let a panic attack take them over and called out to Jesus, "Teacher do you not care that we are perishing?" Jesus arises from sleep and speaks to wind and sea, "Peace, Be Still!"
