Prayerful hands become motived hands.
Sometimes they might, but my observation is that most of the time they aren't. The person praying feels like their prayer goes to their father figure in the sky who will then go to work fixing the issue. It should be clear though, and you must admit, that prayer by itself does absolutely nothing. Why? Because god is imaginary. All there is is the natural world. You could get all
the people in the world praying for the survival & cure of a 3 year old child with cancer, (and all praying to the right god - you know Yahweh), but when the child succumbs to the cancer, all you god believers just stare at the floor and say: "Well, I guess it was just god's will
". An exercise in denial, excuses and intellectual dishonesty if there ever was one.
