Mark 4:35-41

35 Late that day he said to them, "Let's go across to the other side."
36 They took him in the boat as he was. Other boats came along.
37 A huge storm came up. Waves poured into the boat, threatening to sink it.
38 And Jesus was in the stern, head on a pillow, sleeping! They roused him, saying, "Teacher, is it nothing to you that we're going down?"
39 Awake now, he told the wind to pipe down and said to the sea, "Quiet! Settle down!" The wind ran out of breath; the sea became smooth as glass.
40 Jesus reprimanded the disciples: "Why are you such cowards? Don't you have any faith at all?"
41 They were in absolute awe, staggered. "Who is this, anyway?" they asked. "Wind and sea at his beck and call!"
