They woke up Jesus to do something, right? Maybe not.
Mark 4:41 (NIV84) — 41 They were terrified and asked each other, “Who is this? Even the wind and the waves obey him!”
I don't think they thought he was going to calm the waves. I think it is very possible that they wanted someone to share their own anxiety. They certainly didn't expect, by looking at their answer, that Jesus was going to get the wind and waves to obey him. Consider this; misery loves company. I do it sometimes. I want my wife to feel my stress. There, I admitted it. Maybe you are like the disciples and 99% of people who want others to join you in your depression, anxiety, worry, anger or whatever. We don't do it all the time, but it happens. When we think about it reasonably, it is a shockingly ugly thought. I don't want my wife to feel my stress, I want her to de-stress me if anything. Maybe apologies are necessary when we catch ourselves doing this.
The disciples picked the right guy to share their anxiety and fear with. Mr. Fearless. He won't commiserate with you, but He will have compassion on you and eventually solve your issues if you let Him. The storms..., well, He is more about the inside than the outside. But He calms outside storms too!
