Christians commonly say god speaks to them.
What if he asked you to kill your firstborn? What if asked you to go to North Korea and hand out bibles?
My experience with such phenomena is that what you think you would do if asked ahead of time is not necessarily an accurate guide to what you would
actually do in the situation. I find both of those ideas morally abhorrent, as described and with my current inclinations, but then God hasn't made any attempt to induce me to do them. It seems to me that if an omnipotent being exists, it probably does not struggle to talk people into things, else what good is omnipotence?
Then you reject the bible. God talks to people, or they think he does. God tells Mother Teresa to help the absolute lowest people in India and she is a saint.
God tells someone to kill prostitutes to purge veil from the world and he or she is a murderer.
Both cases have biblical antecedents.
I sat next to a Jew on a jet. He put a small block with symbols on his forehead and covered his head with a cloth. He told me he was commung with god.
I was invited to a private evangelical meeting of about 2o people. People having visions and the like. To Christians god is real and tangible. If you do not believe that then you are not Christian, at least by the bible.
In the RCC one believes on morality the pope speaks for god. Instead of a Bat Phone he has a God Phone. Excuse me cardinal Jones, the red light is flashing on t3e god phone.
The question posed in the OP is not trivial. The Law And Order show touched on the issue of civil law and religious freedom. God told me to do it, I was on a mission from god dealing with immorality and evil as a defense.
Christians transform scripture into 'god tells me to do this'.
