If God wants something from me, he would tell me. He wouldn't leave someone else to do this, as if an infinite being were short on time. And he would certainly not leave fallible, sinful humans to deliver an endless plethora of confused and contradictory messages. God would deliver the message himself, directly, to each and every one of us, and with such clarity as the most brilliant being in the universe could accomplish. We would all hear him out and shout "Eureka!" So obvious and well-demonstrated would his message be. It would be spoken to each of us in exactly those terms we would understand. And we would all agree on what that message was.
