Luke 8:23-25

Those that put to sea in a calm, yea, and at Christ’s word, must yet prepare for a storm, and for the utmost peril in that storm; There came down a storm of wind on the lake (Luke 8:23), as if it were there, and no where else; and presently their ship was so tossed that it was filled with water, and they were in jeopardy of their lives.

Perhaps the devil, who is the prince of the power of the air, and who raiseth winds by the permission of God, had some suspicion, from some words which Christ might let fall, that he was coming over the lake now on purpose to cast that legion of devils out of the poor man on the other side, and therefore poured this storm upon the ship he was in, designing, if possible, to have sunk him and prevented that victory.
