It's quite popular today to believe that morality is not something that stands above all of humanity but that moral laws are themselves created by humans. Consistent Christians should deny this view; the Bible teaches that moral duties come from God and are therefore objective and not relative to an individual or to a culture. Yet, most people don't have a good understanding of what we even mean by morality or what is necessary for certain values and duties to be considered moral at all.
In this video clip, Lenny reviews three specific components that must be accounted for in any moral framework: how do moral obligations obtain, does the person have real moral freedom, and is there a genuine responsibility that attaches the obligation to the person in question. Any theory of morality that is missing one of these components cannot explain morality in any meaningful way.
