Paul warns believers not to remain immature children, 'tossed by waves and blown about by every wind of teaching, by human trickery, by craftiness in deceitful scheming' (Ephesians 4:14). The word originally meant dice-playing, then extended to the cheating and manipulation associated with gambling. False teachers operate like dishonest gamblers, using sleight of hand and deceptive tactics. The metaphor suggests both randomness (dice) and calculated deception (loaded dice). Spiritual maturity recognizes such manipulation.
