In today’s world where people are always offended by something silly it’s incredible that this bet is gaining popularity. I’m surprised Christians are not finding this offensive but are seeing the humor in it.
I am a Christian and I find this offensive, even as a responsible gambler I don't like this type of gambles, only jesus christ knows when it's best for him to return, it's not shown to anyone in the world when that time will be.
Although there are clues in the Bible but not precisely, in the end we humans aren't the one to make the decision, it's left for Jesus to come when he feels like it's the right time.
Sorry I won't dare try to make money off this, I will rather move on and gamble normally like I used to, only on sport bets and casinos.
