@baddog1,
This is a great question mate...
Here is my view as a believer...
The Bible never claims that gambling is a sin...
But most would probably think that it is by being prudent like the Bible says...
But in any event going by scripture alone...It basically comments about certain things are just a waste...Or wasteful...meaning it is not really a sin...But it does not really help you in any sort of way...
So it really isn't any different that going to eat at a fancy resteraunt...Or spending excess money on a lofty pair of shoes or something...
But it is just kinda a waste to do it...Because it does not really help you in any sort of way...
And could be a problem...
I guess so long as you do not let it consume you, it is not really a problem...
But if it does, then it would be a sin...If you will...Hope this helped...
