There's a difference between, say, someone who's religion forbids seeking medical attention when something goes wrong, and someone who uses their faith in God as a source of strength and peace while they're doing everything humanly possible to prevent or address the problem.
To me, it doesn't sound like the OP is proposing we do away with medicine, or charity, or common sense. Sounds like she's just suggesting that faith in God can be used as an anecdote for anger and self-pity.
Anger and self-pity are killers just as sure as disease, or starvation, or car crashes. . .
With the added anti-bonus that while all of the above are events, anger and/or self-pity can be life-long debilitating conditions.
