I also saw some atheist statuses complaining about the uselessness of the prayer statuses. And that really pissed me off.
People have many different ways of coping with stress or heartbreak. Some people drink or go on medication. Some seek out the company of family and friends, some seek time alone to reflect. Maybe you journal more, maybe you write a poem or paint something or garden. And guess what? Some people pray.
So two things:
1. As long as they don't hurt others, I don't care what people do to get through the hard times in their lives. If they've found something that helps them, I'm glad for them. Do I believe God answers prayers? I don't even necessarily believe God exists, and no, I don't see a lot of evidence that people get what they pray for. So what? I also don't think alcohol and poems and paintings will magically make your problem go away, but that's not really the point, is it? They are all different methods of processing emotions, of working through grief. I'm not such an asshole as to tell grieving people "This doesn't work for me, and therefore it's useless for you to try it." Wow.
2. Prayer actually does help people. Maybe not in the "If I pray long enough, I will win the lottery" way, sure. But research has found that prayer can be a psychological balm, much like meditation. I get not believing that prayer can stop bullets, but it's just incorrect to say that there's no "power" in prayer. For those who believe in prayer, it can be quite powerful. And I'm glad those that believe in prayer have one more tool to help them help themselves and each other during really difficult times.
