The "word of God" is an important and often-used concept with apologists. They have texts they claim contain the words of their god and they justify their ideas by insisting that they ultimately come from the words of their god. For some reason, though, we don't encounter any gods actually doing any writing or talking. It's always humans doing the writing and talking. Are they ventriloquists dummies? Is it just coincidence that their god wants and believes what they want and believe?
I doubt I could find another human being who believed all the same things I do. Perhaps there are a couple out of the billions on the planet, but it doesn't seem likely. The same is true for the rest of humanity — whatever they believe, they'd have trouble finding someone else who agreed with them on everything. Humans, though, are more like each other than they would be like any god. Granted, I'm pretty great, but even I'd be hard-pressed to describe myself as "god like."
So just how likely is it that someone will share all the same beliefs, attitudes, and prejudices as a god? Any god? I think I'd find a person claiming to present the words of a god to be a bit more credible if they admitted that their god wanted things which they themselves didn't want, but were reluctantly going along with on the assumption that this god knows better. There are obviously problems with such a position, but at least they wouldn't be giving the impression that they are simply using "god" as an absent authority figure to justify their beliefs without having to actually argue for them.
Wherever we look, people claiming to have the "Word of God" keep presenting words that reflect their own cultural, political, and social prejudices. A different "Word of God" for every cultural, political, and social context. What are the chances that this isn't just lots of different people who have beliefs that they can't or won't be able to support, but hope to give exaggerated authority to by attributing it all to a deity who isn't around to confirm or deny the allegations?
If a god did exist, it surely would have hired a better PR firm by this point.
