Trying my best NOT to stereotype, but I find many people of this view of (whatever) faith. These people generally adhere to texts and rituals without trying to utilize such rituals to strengthen their inner selves.

I have told one of them in my community that it is them who cause others ( stereotypically younger generation ) to drift AWAY from faith ( regardless of which faith it is ).

Back to survival.
Faith AFAIK does not strip us from our responsibilities or capabilities. It just says that our decisions and deeds should follow some guidelines.

An interesting point here seems to do with some religious restrictions. For example, some faiths impose food/diet restrictions on thier followers. It is inetresting to think of such restrictions as positive or negative for survival.
