"Do people consider prayer or attending church not necessarily something that manages stress?” asked Lynn Bufka, a psychologist with the APA’s Stress in America team. “We don’t know.”

Her question is confused, prayer is not the same thing as attending church. She might as well have said, prayer or drinking coffee and watching squirrels eat from the bird feeder that I just refilled.
No wonder she then says, 'We don't know'
If you start with the wrong premises, you cannot get anywhere.

I would add another question, can you pray if you don't believe in God? Paul seemed to say no, that those who pray to God must believe he exists.

I see many people watch the news as if the President himself were going to call them at any minute to ask for their expert opinion.

Even the Bible tells us there is stress in going out on the street--lions are there!

I remember George Barna put out a book a while about, "Revolution" about how the institutional model of the church was dying out. He wasn't exactly crying over it, nor calling people to come back to it.
I think a Reformed author, last name DeYoung, may have put out a book or podcast to call people back.

Why has this happened? When Christians turned over the education of their children to the state schools, and the religious education to the church, despite the Bible saying it is their job to do it.
