I can't tell you how many times I've debated a Christian who believes that human morality is subjective and God's can possibly not be. God is asserted to be the one true objective standard that humanity's morality is grounded in.
And what if your God changes his mind?
According to Christians, God can not change his mind because this would be against god's nature. (Whatever that is.) God remains consistent within the framework of his "plan" because god is "unchanging." (Obviously, they've never read their bible and put any independent thought on the matter.) Otherwise, if god could change his mind, he wouldn't be objective and more like us. (In other words, they believe that God is something akin to a computer program.)
Christians don't believe it though, because why do bother praying to God? To change his mind? If its his plan, a line in the code, for your mother to suffer months of chemo only to die of cancer later, you think you can change god's mind? He has "plan" after all, and you think you can alter it? And if God later decides to save your mother's life from cancer where it was specified that she should do so, then how can you say God has a plan?
Christians do anyway, and so much for an objective and unchanging god.
