Well, this is getting away from the OP, but if you consider God as the creator and source of reality, then He also created things that are objectively true. Arithmetic might be objectively true, but 2 + 2 = 4 is objectively true because God created it that way.

But suppose I came to you and declared that 2=2=4 was objectively true. And you disagreed with me. Then I took two rocks and two more rocks, and you counted them and came to the conclusion that there were four rocks. This is how I convince you that 2+2=4. And the more we think about it, the more it seems to us impossible that there could be any other answer.
But now suppose I come to you and declare that “Thou shalt remember the Sabbath day and keep it Holy” was objectively true. And let’s say that I had a divine revelation that demonstrated that objective truth to me…a burning bush spoke to me. Note that it doesn’t matter what objectively true moral statement I put in there, only that we stipulate that some sort of objective morality exists, and that I have been convinced of the truth of that objective morality, and that I’m trying to convince you, in the same way I convinced you that 2+2=4.
How do I go about doing that? Unless you also recieve a direct revelation from God, how do I demonstrate that my objective morality is objectively moral? It seems to me that every attempt I make to convince you that my postulated moral code should be adopted must be made by appealing to your subjective sense of right and wrong, of good and evil. Your personal preferences, in other words. Unless I can demonstrate the truth of my objective moral code as simply as I can demonstrate that 2+2=4, or as subtly as I can demonstrate that the Earth is spherical and revolves around the Sun, what exactly is the difference between my supposed objective moral code and all the myriad other subjective moral codes?
In other words, suppose someone stumbled upon an objective and perfect moral code, how could that person know that this putative objective moral code was the correct one? I don’t see, absent divine intervention, how this can be done.
Of course, then you give the standard rejoinder, if all moral codes are subjective, then why would I prefer a moral code that says it’s wrong to send the Jews to the ovens over one that says it’s right to send the Jews to the ovens? It would be like saying that blue is better than red.
And the answer is, if I genuinely prefer blue to red, then I really do prefer blue over red. I really do prefer a holocaust=bad morality than a holocaust=good morality. But WHY, I hear you you ask again.
Because that’s the sort of person I am. I was created with certain likes and dislikes, through the process of evolution over millions of years, and here I am, willy-nilly. I dislike pain, I dislike hunger and thirst, I like sex with women, I like hanging out with other members of my species, I like taking care of children, and on and on and on, and I didn’t consciously choose any of it, nor can I consciously choose to hate children and hate sex and enjoy hunger.
Evolution doesn’t make loving my children MORAL, it simply made me the kind of creature that loves my children. And hence, I prefer the kinds of social organizations that tend to make a good world for my children to live in, and dislike the opposite. My preference for my children to live isn’t moral by any objective standard, but it’s my standard. Food isn’t objectively better than poison, living isn’t objectively better than dying, but SO WHAT?
Evolution doesn’t provide me with my morality, evolution merely created me as a particular kind of organism that prefers certain kinds of things. Having more offspring isn’t more moral than having none, that’s not the argument. The argument is that there is such a thing as a human being, and given the human being’s evolutionary history that human being is going to have a certain nature, and a given human being isn’t going to like things that are contrary to its nature.
The fact that I can recognize the source of human nature as evolution rather than God doesn’t mean that I deny human nature, or that I am a nihilist or a sociopath, any more than believing that God created human nature would render me a nihilist or a sociopath, or would make me hate my nature. Why would it?
So even if we stipulate that your postulated God-given objective morality exists, how can we access it? How can we know that it is? In practical terms, how is the universe different if we imagine an objective moral standard that we fallible flawed mortal human beings cannot know directly, or if we imagine fallible flawed mortal human beings expressing their subjective moral preferences?
