One who derides, ridicules, or makes sport of holy things. The biblical category is sharp and recurrent. Proverbs 20:1: Wine is a mocker, strong drink is raging: and whosoever is deceived thereby is not wise. Isaiah 28:22: Now therefore be ye not mockers, lest your bands be made strong. Jude 18 prophesies: How that they told you there should be mockers in the last time, who should walk after their own ungodly lusts. The mocker is the man who has cultivated a posture toward the holy that responds with sneer rather than wonder, with derision rather than awe, with comedy at the expense of God rather than worship in His presence. Lot's sons-in-law thought he was mocking when he warned of the coming destruction of Sodom (Gen 19:14) — a poignant inversion where the warning is treated as mockery by men whose entire life had become mockery of God. The Christian recovers the disposition of reverence and refuses to be one of the last-days mockers Jude warned about.
