Hi, Humbled I would never say that people should not pray or automatically cry out whether within or audibly in times of crisis or need.
E.G I find myself inwardly hoping/wishing that my son who works in the oil industry will return safe and well to his family.
I am almost making a plea to all the circumstances which will allow that to happen ie favorable weather, his own safety awareness, a well maintained chopper etc.
But my plea, hope , wish even prayer if you like is not based on the supernatural. My hope that all will be well, will be absolutely down to natural and humanistic causes.
The soldier in the trench may pray , cry out to be safe that is part of being human, but what will guarantee his safety?
It will be the fact that all bullits missiles miss him and that he avoids capture. God will have nothing to do with it.
Remember theists must believe that god looks after his enemy also .
