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.
It is pretty much all kind of people on the internet, give it enough time, you will see someone on YouTube taking about this, some pastor and his church talking how offensive this is and how it is a major sin to even put money on something which has anything to do with guessing the second coming of Christ. In the meantime, it is good to see there is people who just take it easy and see this with a little bit of humor.
I am living in weird times, when there is war and conflict all around us, so It would not be surprising at all if some people in the west believed the end of the world is upon us and the savior is coming to guide his people to the messianic age of peace, the world being governed from Jerusalem.
Anyways, any christian with a minimum of control over their character will simple shrug this off and continue with their routine without being too bothered by it.
