Hoops, why do these people bother praying for God's help at all?
That is a good question isn't it? What is prayer for? I can tell you this: God is not held to the whim (or the cries of despair) of us. Prayer doesn't change Him, it changes us.
Do they believe that he can help them?
I don't know what they believe. I only know what I believe. And "yes"
I would posit that these people did either believe it, or at least hope it.
It would seem so.
I don't know what you're trying to get out of us here.
I have been quite direct. at the point that one is staring down a tornado and one prays for God to save one from it, what would you have God do?
Are you trying to demonstrate that the idea that God should have done something to save these people is unfair, or unjustifiable
No more or less fair or unjustified than I should be saved.
or all a huge misunderstanding of what God is about?
Yes.
In the Bible, God stopped the rotation of the Earth to give the Israelites more time in the day to finish the slaughter of their enemies. God caused the waters of the Red Sea to part so that the Israelites could cross over it on dry land. God caused the walls of the city of Jericho to collapse catastrophically after the Israelites shouted and blew their shofar in unison.
Those are an entirely different subject.
Are you saying God could do all this s***, but couldn't divert the path of a tornado by, say, 100 meters so that it missed this particular mobile home and thus spared this faithful family,
He certainly could. Are you prepared for God to act upon creation in such a profound way at the behest of our prayers? I doubt it.
and that we're all being unreasonable to expect that he do it?
Yes.
