"Our twelfth article of faith
states our belief in being subject to civil authority and “in obeying,
honoring, and sustaining the law.” But man’s laws cannot make moral what
God has declared immoral. Commitment to our highest priority—to love
and serve God—requires that we look to His law for our standard of
behavior. For example, we remain under divine command not to commit
adultery or fornication even when those acts are no longer crimes under
the laws of the states or countries where we reside. Similarly, laws
legalizing so-called “same-sex marriage” do not change God’s law of
marriage or His commandments and our standards concerning it. We remain
under covenant to love God and keep His commandments and to refrain from
serving other gods and priorities—even those becoming popular in our
particular time and place." - Elder Dallin H. Oaks, Sunday Morning Session, October 2013 General Conference.
This is my favorite quote from all of conference. As we look around us and see that laws of men changing due to social pressure from various forces, this quote reinforces that God is the same yesterday, today and tomorrow. It reaffirms that the Gospel of Jesus Christ follows Heavenly Father's plan and not mortal man's. No matter what man with his agency decides to do, it will NOT change the Gospel of Jesus Christ.
"Surely the Lord God will do nothing, abut he brevealeth his csecret unto his servants the dprophets." - Amos 3:7
This scripture from the bible lets us know that the Plan of Heavenly Father is revealed through his chosen prophet and not through just any man, woman, or child in the world. Today that means revelation for the Plan comes to Thomas S. Monson. He is the one chosen by the Lord to lead this church and receive revelation. So has it been since Adam, so it will be after President Monson passes.
We have the agency to ask for ourselves if the words of the prophets are true. Anyone who feels that the words spoken in conference are in error have every right to get confirmation from the Holy Ghost. That is how I go about it. Normally however the Holy Ghost tells me in the very moment I hear the words that they are true and not contrary to the Plan.
