Is gambling OK? Don't bet it! There's not an easy or instantly obvious proof text answer to that question.
In my own point of view, gambling is not a sin if you can control yourself when you play and if you are not an addict in gambling because when you only play, you only play on it not making it as a hobby that will come up being addicted on it. That's why it is better to limit yourself when you are playing.
Same here, I don't consider gambling a sin, In my point of view, I see it like an entertainment, I always play gambling, and I feel so good, really, gambling can relax my mood. I don't know why i can call it sin, when it can give me a great feeling, Personaly, I like gambling, it help me a lot in my life, Really, i don't care if i lose some bucks for my happiness.
