Wouldn't this depend on their Church's teachings and what their section of that religion says about gambling. Article doesn't even say if he was gambling with his own money, or with the money of the church. And that makes a huge difference when we talk about morality of it.

But result was definitely good, if Emmanuel Mutumwa didn't happen to lie and use most of it for himself, and either this casino isn't secular and actually believe that god was involved, or they find out that he cheated, and that just got left out because of pr reasons of the church. This has fiction written all over it anyway if they just interviewed that religious leader and not the casino.

What ever the case is, apparently this casino shouldn't be anyone's first choice if they fear bankruptcy after $30k win.
