I don’t think the best strategy for a Christian is to look toward science fiction writers for their theology. If we all did that, we might have to become Scientologists!
It has been rumored, but is probably not true, that Scientology was created on a bet between Hubbard and Heinlein. It seems out of character for Heinlein, if not Hubbard.
But wisdom can come from many sources. Have you studied any of the Native American Coyote stories?
