Gambling is not necessarily a sin

I've argued before that gambling is not necessarily a sin. If (1) we are not addicted, (2) we are doing useful work, (3) the money is not needed for our other duties to family, church, government or self, (4) we have the time to gamble and (5) we are not coveting riches or (6) making an idol of the Lottery, it is quite possible to gamble without sin. I'm glad to see that Revd Prof John Frame agrees with me! [Despite the potential dangers of gambling etc.] "This is not to say, however, that it is always wrong for an individual to gamble.” Entering the office football pool “can be a harmless bit of fun, strengthening personal relationships.” (The Doctrine of the Christian Life, P&R, p807)
