Mark 4:37-39
37 And there arose a great storm of wind, and the waves beat into the ship, so that it was now full.
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?
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.
Psalms 107:25-30
25 For he commandeth, and raiseth the stormy wind, which lifteth up the waves thereof.
26 They mount up to the heaven, they go down again to the depths: their soul is melted because of trouble.
27 They reel to and fro, and stagger like a drunken man, and are at their wits’ end.
28 Then they cry unto the LORD in their trouble, and he bringeth them out of their distresses.
29 He maketh the storm a calm, so that the waves thereof are still.
30 Then are they glad because they be quiet; so he bringeth them unto their desired haven.
As you can see from the above, the event of the storm was the fulfillment of prophecy.
Luke 24:44 KJV And he said unto them, These are the words which I spake unto you, while I was yet with you, that all things must be fulfilled, which were written in the law of Moses, and in the prophets, and in the psalms, concerning me.
