Scripture never says we should gamble at games of chance to gain wealth. There are many scriptures about money and ways to gain and use money. The book of Proverbs is full of wisdom about how to properly steward our money and possessions. For example, an employer gains from your work, and you gain from the wages.
Yes, there will be the occasional big winner, but it only happens at the expense of many losses from others. The people in charge of gambling in casinos, at sporting events, lotteries, etc., have calculated the odds and they are highly in their favor and against the gambler. A lot of wisdom and knowledge are applied in these types of risk. These types of risks are usually thought through and the risk/benefit probabilities well-calculated. Businesses risk investments in expansion, farmers risk planting seeds for a crop, and individuals risk money in savings investments to grow an income. This is not to be confused with the risks that are inherent in life.
By gambling, we are referring to games of chance at places like casinos and sporting events. The Bible doesn’t specifically say anything about gambling, but it does have a lot to say about using godly wisdom when it comes to managing our money and possessions.
