The wagering of value on chance for personal gain. Not addressed by name in Scripture, but failing biblical principles in several directions: (1) stewardship — God's resources entrusted to His people are not to be risked on chance; (2) work — the biblical pattern is honest labor that has surplus to give (Eph 4:28), not winning others' money; (3) contentment — gambling appeals to the desire-for-more that 1 Tim 6:6-10 names as covetousness-and-the-love-of-money; (4) love of neighbor — the gambler's gain requires another's loss; the systems of casinos and lotteries extract most heavily from those who can least afford it. The Reformed and Puritan traditions have generally treated gambling as incompatible with Christian discipleship, though some Christians distinguish between social low-stakes recreation and serious wagering as a way of life. The MOOP Dictionary holds the stricter position: the disposition that gambling cultivates is uniformly unhelpful to Christian formation.
