I'm afraid that I think it is awful to promote the belief that the Christian God, or Jesus, or the other one, or maybe Mary or maybe saints, or maybe would-be saints, are all somewhere waiting for requests to come in, and then deciding which ones to grant. In my view it encourages irrational behaviour. I don't like one religion pushing itself like this.
It's a pity that proper research isn't done to check the results of prayer, from all faiths and none. We might get some interesting results. Perhaps insurance company data would be useful in comparing life expectancies of people from different religions (who would be likely to pray or be prayed for).
I know that faith and prayers are probably comforting to many, but why not check it out scientifically? It would be marvellous if it turned out that there is something solid behind it all. Then there would be far more people joining religions; of course, some religions might turn out to be better than others.
