If there is a god who is omniscient and benevolent, then why has humanity suffered the way it has in so many millennia?
If he is omniscient but not benevolent, and cannot stop death and destruction,then he is not a god.
If he is benevolent but not omniscient, and cannot see the chaos, then he is not a god.
If he is neither, and can do nothing to stop what he cannot see, then he is not a god.
"God works in mysterious ways" cannot account for the millions upon millions who die in horrid ways, and the people who continue to suffer a similar fate.
I've heard some say "Our Lord is a jealous god", to which I say that jealousy infringes upon the idea that a god would be perfection in the most holy form.
If there is a god, they are not perfect. They are not all-powerful, or maybe they aren't all-seeing. Maybe they just don't care anymore. I don't know if there is or isn't a divine entity, but if there is, they will hear no prayers from me. Not now.
