Does anybody? Assuming the Abrahamic God exists, the last information we have about them is over 2000 years old. What if they've changed their mind on stuff like murder or mixing fabrics?
If anything it is us that have changed our minds, and we continue to do so. How likely is it that our culture will change its mind on what murder is, and what acts it encompasses, and the degree of good or evil... in the next generation, let alone two millenia?
It's interesting you automatically assume it's "truth", not random opinions. And yes, we, collectively as humanity, have evolved since two millennia. E.g. we no longer consider slavery normal. So using opinions from 2000 years ago that were made in a drastically different environment simply doesn't make sense. It's like using laws from the 1920s and applying them to Internet stuff. It just doesn't make sense, the writers couldn't have imagined the world we have today, so why is their opinion relevant?
Well, not automatically. I confess my automatic response is to go with what is easy. It is certainly easier to believe there is no God like the Abrahamic God we must pay attention to, and like you say because things change we just can't trust that some things will never change... but my friend in response to the rest of your comment I've found easier isn't always the best way to think about things.
