The things you do for fun are always going to be done more enthusiastically than what you do for duty, and one really should not read scripture, pray or go to church for entertainment.
You seem to be suggesting that anything one enjoys is "entertainment." I enjoyed tax accounting when I was employed, but it wasn't entertainment. I enjoy cleaning the floors, if I can get all the kids out of the way for an hour, but it's not entertainment.
If you mean that Scripture, prayer, and worship aren't enjoyable, then that's pretty sad.
I knew something bothered me about thar post. Your rebuttal said it beautifully.
