They may say it but they dont, most of them use it in place of "dang that sucks bro" How do you know they don't? I dont in the slightest. In my own personal experience only the hardliners say it and they say it to every other person they talk to. Perhaps they do have quick prayers every minute or two, that or keep a mental or physical note. Or they say it for the sake of conversation, and to express their views. I haven't a clue but I lean towards the latter out of my personal biases. Speaking out of personal experience, I know many people who make a point of praying for specific others regularly when they've told them they will. Of course, you can argue about whether prayer actually does anything, but I don't think you can argue that it's a nice thought at very least if the person praying for you thinks it's doing good.
