God is not needed to set this record straight. It was straight to begin with, and there are many, many people today who can straighten out the proposals of those people in the last few hundred years who were convinced they knew better than their own elders. They have already been debunked--God has no need to do what has already been done.
Okay, here's the thing, you Christians have been murdering each other for a thousand years over interpretations of what the Bible "Really" means. That is when you haven't been murdering indigenous people for their beliefs, or Muslims or Jews for not believing that shit at all.
"You don't believe in Transubstantiation?"
"Um, nope, doesn't taste like flesh and blood to me, just stale bread and cheap wine!"
"DIE, HERETIC!!!!"
Human life and life on earth has ickiness. We would question if those icky bits were not included. Do you have something specific in mind?
Um, yeah, reject the whole thing as a lot of pagan superstition and have a belief system based on science and reason.
The problem is, you guys leave out the ickiness because you want to deny your Sky Pixie endorsed it. Slavery. Not God's fault, even though he endorses the practice throughout the bible. Never once in the bible do they say Slavery is wrong. (Moses didn't want to end Slavery, he just wanted the Hebrews to return to Canaan).
Witch Burning? Today we know that there aren't women who gain power through selling their souls to Satan. But man, 300 years ago, people thought that shit was totally real and burned women for that. The bible said so.
We are seeing a similar thing with homosexuality today. In 50 years, all the churches will denounce homophobia and perform gay marriages... and try to pretend that wasn't REALLY what God meant.
God doesn't change his mind, but we change ours.
