Mark 4:38 And he was in the hinder part of the ship, asleep on a pillow: and they awake him, and say unto him, Master, carest thou not that we perish?
Mark 4:39 And he arose, and rebuked the wind, and said unto the sea, Peace, be still. And the wind ceased, and there was a great calm. 40 And he said unto them, why are you so fearful? how is it that you have no faith? …. Jesus, being tired and hungry from the events of the day, had fallen into a deep slumber, but as far as He was concerned, they were safe in His Father’s arms who would take care of everyone on board.
Therefore, the most important fact about the disciples’ experience was that Jesus was on board. Whether it was storm or calm, or anything else in between, the mere fact that Jesus was on board would make all of the difference. An important commentary on this particular event is written by the servant of The Lord, in which she describes the peace that enshrouded Christ, and the issue which caused the disciples to go into panic mode.
[The Desire of Ages pp 334] Absorbed in their efforts to save themselves, they had forgotten that Jesus was on board. Suddenly, a flash of lightning pierces the darkness, and they see Jesus lying asleep, undisturbed by the tumult. In amazement, and despair they exclaim, “Master, carest Thou not that we perish?” How can He rest so peacefully, while they are in danger and battling with death?
Mark 4:41 And they feared exceedingly, and said one to another, what manner of man is this, that even the wind and the sea obey him?
May God add His blessing to the study of His word. “Good night” and God bless!
