The commands God gives come from who He is, not from what He deems right or wrong. So, God's objective morality comes from who He is, this encompasses far more than we can understand, God says " your ways are not my ways and my thoughts are not your thought." In other words, God knows way more than we can begin to understand and His judgement will always be righteous, who is a liar and who is not will be determined by God according to who He is.
God loves those who believe and those who do not and the same goes for me, you have no choice in this matter. That puts the matter of total free will to rest.
