Share for Prayer?

I have come across many of these things on various sites. For the most part I see them on FaceBook but I have noticed many start out at Tumblr or Instagram. I have to wonder when I see these things with almost 60,000 shares from a single instance, who could possibly have ANY sort of FAITH in something like this. I don't make any claim to be the bearer of any great religious knowledge, but from what I do understand about most of them......."you shouldn't SPEAK for your God".  To me this would seem almost like a slap in the face of any real higher power that may be. It doesn't matter which God you  pray to or what religion you cling to, I doubt seriously some guy with a Photoshop program can offer to be your personal publicist to gain your Gods favor for you. I see a lot of people post with such shares things like.."well it's worth a shot" or "Can't hurt" and other little mental reinforcements to themselves to insure they receive their free gift from their particular deity.
