Irony: the disciples who after seeing Jesus’ supremacy over the storm, ask, “What kind of man is this?” receive their answer from demons once they come ashore. Jesus is the Son of God, the Sovereign Judge before whom demons fall, beg, and tremble, the One who in the weakness of His exhausted human flesh beats up a legion of demons with a single word. Learn from the demons not only who Jesus is, but that intellectual assent is not enough (James 2:19).
Insanity: the locals learn to tolerate the kingdom of darkness, but when Jesus demonstrates His power over the realm of evil they beg Him to leave. They prefer pigs to persons and swine to the Savior.
