>>63010057With God as the judge of objective morality, we have an outside source of morality, not based on every individuals subjective ideas. With an outside source, we are able to judge one another and discern right from wrong, both by God's declarations, but also by our own conscience (which is admittedly flawed), but this is where the idea that basically all people groups think murder, stealing, etc. are wrong comes from, and why we are able to band together and makes laws and justice systems saying that they are wrong, because it's not based on our subjective individual morals, but our (mostly) shared God-given conscience.
