I am totally opposed to legalized gambling, but that is not the issue here.
The issue is how to lure people into "investing" in a cause where the evidence of success is very lacking.
If God wanted to promote obedience to his religion, he certainly has been quite ineffective.
He appears as flaming shrubbery and says, "stop worshiping gilded livestock and I will give you real estate", and then causing them to lose it to Assyrians, N=Babylonians, Greeks and Romans.
He says. "Once you screwed up and I knocked down your tower and made you all speak different languages".
And he says, "If you look back at the destruction I have caused, I will turn you into a pillar of salt."
And he says, "I will drown each and ever living creature (well not the fish)" except eight of you.
Then he becomes a human and gets himself crucified and has a very unpleasant weekend. And 2000 year later, despite promises, he has not returned.
And keep in mind that the Biblical character called "God" s omniscient and KNOWS THE FUTURE.
He knew when Mohammad was born that the entire Middle East was going to be lost to Christianity.
You know I am not making stuff up.
