University of Toronto psychologists reported last year that "believing in God can help block anxiety and
minimize stress," their research showcasing "distinct brain
differences" between believers and nonbelievers."
I guess the key terminologies here are that a "belief" in God helps to "relieve" depression. Therefore they're not saying God is real and they're not suggesting faith as a substitute for medicine. However I'd like to see the fallout from this finding. I think all they're proving is the power of the brain and the body.
My personal experience is opposite. My depression actually helped to kill my belief in God and now I'm actually happier.
