Here it is important to understand why the House of Israel is so privileged. QUOTING FROM THE BOOK: THE LORD'S CHOSEN PEOPLE
“ …Whether they love the truth here or not, the Lord still recognizes their chosen linage, as was the case with most of ancient Israel in Moses time and thereafter.”
“In spite of unworthiness or wickedness of God's chosen people at any given time in history, the Lord has still taken special note of His chosen people throughout the ages. This is because they have inherited sacred birthrights which they received by covenant in their premortal world, and those birthrights are set in stone. It is also because of their disposition and natural inclination to repent, and eventually qualify for the birthright blessings that flow from their birthrights, and thereby win salvation for themselves, and also because of their disposition and special capacities developed in the premortal world to help the Lord carry out His marvelous plan to bring salvation to the rest of His children.” “ The Savior's love for the House of Israel is beyond comprehension of mortal man. Even before the creation, the House of Israel were given to the Savior as His foreordained birthright and inheritance.” Deut 32:8-12, Isaiah45:4, 1Peter 1:2
Elder Dallin H. Oaks
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 though 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 of 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 to our particular time and place.
Joseph Smith
God never has-he never will-institute an ordinance or give a commandment to His people that is not calculated in its nature to promote that happiness which He has designed, and which will not end in the greatest amount of good and glory to those who become the recipients of His law and ordinances.
Joseph Smith
"Man does not have the right to adjust the application of God's laws. But God has every right to do so..."
