2nd child of Pa. couple dies after only praying:
A couple serving probation for the 2009 death of their toddler after they turned to prayer instead of a doctor could face new charges now that another son has died. 

To be fair, in my background we were never taught to use prayer as a substitute for professional medical care.
Still, given what the Christian faith teachers about the power of prayer, you can certainly see the logic of these parents.
The fact that this kind of prayer does not work kind of makes you question the whole thing, no?
