A Prayer is as harmless, as the very words that come out of your own mouth.
Has any Prayer ever been arrested for rape, murder, abortion, terrorism, and so on?
I'll answer that question for you, unless you have legitimate REAL WORLD evidence, that could be provided said, that states, since Jesus himself walked the earth, that YES, prayer has been arrested for harming humanity itself?
Because the REAL WORLD answer is NO, no Prayer has ever been arrested for the above crimes, since Jesus himself walked the earth.
"Prayer is an action."
"To say that the actions of parents are to blame for the death of a child and that those actions (prayer) are harmless is not a coherent view."
