The love of money is the root of all evil. But Gambling is an activity isn't it, and there is no rule against gambling in the bible. It's unwise to gamble too much, obviously. Sometimes it can be a harmless form of amusement if you don't abuse it.

Seriously what is wrong with you, that you have to nitpick everything. I wouldn't even mind if you were right even half of the time, but, you just, love to be wrong.
