God gives us prophets so we know what we need to focus on in our time and situation. If we hold to them we are more guided. Our head prophet, besides Jesus Christ, is Russel M. Nelson.So morals change? Why?
Doesn't;t that open the door to any human insisting they have the newest version of morality? Look at suicide bombers exploiting this loophole. Can you say they are wrong? Maybe they are doing God's will and you are living with obsolete morals, possible?
