In his column, "Casino gamble? A bad bet after all," Joseph Farah states that gambling is not a sin.
Gambling is a sin, since it is larceny in our hearts: The gambler is driven by envy to covet the wealth that others have. It is a violation of the 10th Commandment (covetousness), and may be a violation of the Eighth Commandment (theft).
The Bible states that we should not "reap where we do not sow" (John 4:38), an argument against usury that also covers gambling as well as modern ideas of "wealth redistribution." It is wrong to want something for nothing.
