Well, actually, it doesn't quite say that, at least not the way I read it. Prayer has an influence, yes (I work at a research institute that has conducted such studies), but we do not know for sure (at least by the parameters of this study) that it is coming from God. It may be the energies from the person doing the praying that is somehow influencing the situation directly - the idea that the mind/positive thoughtwaves, etc. have an influence over us biochemically. That the powere is within each of us to do this. Now, it may very well BE God, but this study does not conclude that.
