Me too. Roman War Criminal and I have discussed this in the past. Jesus say that "few" find salvation. Few by definition is less than 50%, and probably a lot less.
The US is the most Christian on earth by percentages. Compared to Europe, China, India, Africa, etc. However, even in the US, the percentage of truly born again, saved Christians is most likely low.
I would say no more than 10%, but probably in the low single digits. Surveys have put the number at between 6% - 35% of evangelicals in the US, but it is ridiculous to believe the number is above 10%.
Recent projections have Protestants on a massive decline, and that includes the main line churches. However, the percentage of those that are truly saved is almost certainly much lower than any official numbers.
Still, after the Rapture, that percentage will be devastating to the US. Other nations......not so much. Islamic nations will barely notice. Atheistic Europe, same.
That graph tells 3 very interesting stories.
1. Protestant continue to move downwards (IE Evangelical Christianity)
2. Roman Catholicism remains the same, as if no impact
3. Those with no religious affiliation have skyrocketed (apostasy)
The question Jesus posited in Luke 18:8 comes to mind:
“However, when the Son of Man comes, will he find faith on the earth?”
My answer: If He doesn’t hurry up - He won’t!
The Vatican will have to tune into CNN to know the Rapture has happened.
