you haven't answered how you can have objective morality apart from Christianity. When your army commander tells you to advance, you advance. When he commands you to fall back, you fall back. Are you being consistent if you consistently obey your commanding officer? Of course. God is perfectly self-consistent, and whatever He does is morally commendable. Whether you emotionally like it or not is logically irrelevant. After all, in your view, your opinions are just chemical reactions in the brain - why should that have any merit at all? Why should baby-killing be fundamentally wrong in your view? You keep arguing as if human beings have intrinsic value, as if they have been made in the image of God and are valued by Him. But that makes no sense if people are chemical accidents like a can of oil
