The following is a real exchange with a Christian Apologist who's written a book and everything.
Christian: If Christianity were true, would you become a Christian?
Me: I would become Christian, but I would try to persuade God to make some changes.
Christian: Because you're so much wiser than omniscient God.
Me: Hey, he occasionally takes the advice of humans in the Bible, and if I was Christian, I would believe that.
Christian: He takes advice from humans? Give me an example.
Me: Exodus 32 shows he changed his plans based on Moses' advice.
(Commentary) In Exodus 32 9 & 10, God says he is angry at the people misbehaving down below and is about to destroy them. Moses advises God to not destroy the people and God listens. Don't take my word of it, read for yourself. There are other biblical examples of God saying is it about to do something and a human talking him out of it, but Exodus is the first that I know.
Christian: I'd hardly call answering a prayer taking advice.
Me: God literally spoke to Moses telling him what he was about to do. Moses persuaded him not to and God did not. What else specifically would you like to see from this exchange to qualify?
Christian: (No comment, links to a GotQuestions which claims God does not change his mind.)
This exchange reminded me that Christian apologetic arguments occasionally conflict with the bible. Apologists depend on maxims like "God does not change" because they support other claims. For example, change denotes time and God is "outside time" and therefore can not change. The author of Exodus wasn't aware of that maxim and therein lies the problem.
Apologists must then make their maxims work within scripture. In this case, if we accept that God does not change, that means he always knew he would say he would destroy those people, listen to Moses, and then not destroy those people. This reasoning, while convoluted, feels comfortable to the apologist in that it fits both God's omniscience and God's unchanging nature within the context of Exodus. But the implications! This means that God knowingly lied to Moses when he said that he was going to destroy those people. God knew that he was not going to destroy those people when he said he was: a textbook lie. An earlier me might argue that God sinned, but I now know how unfruitful that argument is with an apologist. God doesn't sin, full stop, and I can't argue the rules of a made-up concept like sin. God simply lies, which is actually more damning to the Christian worldview. It throws the Word into question. How can we trust what God says given proof that he lies to us?
At this point, the apologist can only argue that God lies to us for some good reason because God is good...he said so...and we can believe him.
