Well, if we are gonna look at this from a Bible perspective, I must make a few points.
God slaughtered an entire land of men, women, and children, so that it could be handed over to "his people".
God also sez you deserve to be tortured eternally if you have sex outside of marriage and do not ask for forgiveness in the proper way.
Etc.....etc.......etc.......
A lot of things in the Bible are completely ignored by modern Christians.. (Hey Christian ladies.. You DO all wear dresses, right? That what the Bible sez..)
Modern Christians believe what they WANT to believe out of the Bible, and gloss over the rest. So, since our society still has Puritanical concepts of "right" and "wrong" ingrained in it, we still believe gambling is technically "wrong". Those that enjoy gambling immensely will, as a general rule, not be seen as a normal person in society.
Do what you want to doi. The Bible is written so vaguely, that there is guaranteed to be a single quote from scripture that justifies what you want to do.
It's been working for Christians for hundreds of years...
