God has already told you what He wants to tell you, and I'm sure you know where to find it (HINT: HOLY Bible).
Is that the same book where He lays out His rules for beating slaves, or killing women who aren't virgins, or forbidding eating at the oyster bar? Yeah, He sounds like a real winner.
How do you know He didn't communicate through the Islamic Quran? Or the Hindu Vedas? Or the Buddhist Tripitaka? Or the Book of Mormon? Or the Sikh Adi Granth? Or the Mayan Popol Vuh? Or the Druid Mabinogion? Or the Egyptian Amduat? Or the Bajoran Kosst Amojan? Or the Norse Havamal? Or Dianetics by L. Ron Hubbard?
Is God AWARE that world is LITTERED in books that claim divine authorship? And He's going to TORTURE people FOREVER just for picking the wrong one? This God of yours sounds like some piece of work!
What's so difficult about bringing His super-all-important message to people PERSONALLY? He can do ANYTHING, right? But instead, He puts it into the hands of fallible, lying humans, for them to hand out to OTHER fallible, lying humans, with nothing but eternal pain lined up for those that aren't convinced by the stories of talking animals and magic fruit trees and dragons and unicorns.
I think that if I were God, and the most important thing to me was saving souls from eternal damnation, then I would put aside my hobbies of giving clubbed feet, cleft palates, and conjoined twins to newborn babies, and I would hold off on ordering African gangs to murder witches who aren't witches, and instead I would make some actual personal appearances. I would put an END to all the people FIGHTING over who has the right interpretation once and for all.
You're not likely to convince me that any morality comes from a book which proclaims that humans should not kill one another, but then FIVE MINUTES LATER provides an exhaustive list of all the reasons you can kill people, like getting tattoos, cutting their hair, or wearing polyester. It's nothing but barbarian justice and ancient myth. If God wants to convince me, He needs to come do it HIMSELF. If He knows EVERYTHING, then He already knew that YOU weren't going to be able to do it.
