I'm Catholic and definitely believe in the power of God.
My grandparents are mid-80s, still go and volunteer and church. They're as healthy as ever (with little exercise).
Others I know in their 60's who don't go to Church struggle walking up stairs and with weight problems.
I don't necessarily believe God keeps those healthy who pray...but, I believe having a trust and faith in God (especially during hard times) helps you both spiritually and physically.
Thanks for all your posts and spreading the word :)
