I think praying has a number of potential benefits. It can be a form of meditation, it can help to focus one's mind on finding a solution to a problem, & either it helps us to program our own subconscious or to communicate with whatever super consciousness there may or may not be. If God or reality has some sort of consciousness that we can communicate with, then God works through people. Though, even if we are just talking to ourselves, "God works through people" is really true either way. It is the people who best understand reality (those objectively closest to God) who are best a shaping reality anyway.
I don't think it is incorrect to refer to the laws of the universe as all powerful. They created everything, they are perfectly strict & unforgiving, & they are impossible to cheat or defy. The only way for any living being to avoid destruction is via acceptance & submission to said laws.
