Perhaps, but also consider how much that higher power fails to accomplish in the lives of so many people. 9 million children a year around the world die before reaching the age of 5, for instance, and their parents, most of them, would have been beseeching that higher power to spare their children, and those prayers were either not answered, or the answer was no. As Sam Harris and many others, all the way back to Epicurus, have pointed out, either the higher power is powerless to prevent such suffering and grieving, or chooses not to, so it's either impotent or evil. Or the simplest explanation, it doesn't exist.
