Yes, the American Church is certainly dwindling in numbers. And there are serious problems that need to be addressed. But as someone who is Gen Z and has many friends who are also Christians in my age group, I think the North American Church is going to become smaller and more vibrant, while in Africa and Asia it is growing exponentially. While in the 50s and 60s many people attended Church as a traditional thing, I don't know if more people were truly Christian. But I digress!
