The biggest problem with all-powerful beings is that they tend to be immortal, too.

So, yes, your Uncle Stan may be trapped under a collapsed outhouse, but the odds of Hrathnor The Mighty answering your prayers promptly are almost exactly zero.

However, if he needs to take a dump, and the only outhouse is collapsed on your Uncle Stan, yeah, he’ll do something.
Just hope he rescues your uncle before magically repairing the outhouse and using it.
