“How thankful we ought to be ... how thankful we are, for a prophet to counsel us in words of divine wisdom as we walk our paths in these complex and difficult times. The solid assurance we carry in our hearts, the conviction that God will make his will known to his children through his recognized servant is the real basis of our faith and activity. We either have a prophet or we have nothing: and having a prophet, we have everything” (Teachings of Gordon B. Hinckley, pgs. 499–500).

Family

(1)  "My dear brothers and sisters, may your homes be filled with love and courtesy and with the Spirit of the Lord. Love your families. If there are disagreements or contentions among you, I urge you to settle them now. Said the Savior:
“There shall be no disputations among you. …
“For verily, verily I say unto you, he that hath the spirit of contention is not of me, but is of the devil, who is the father of contention, and he stirreth up the hearts of men to contend with anger, one with another."
“[But] behold, this is not my doctrine … ; but this is my doctrine, that such things should be done away.” 3 Nephi 11:28–30 
(President Thomas S. Monson, As We Close This Conference, General Conference, Apr 2012) 

(2)   "Marriage and family are ordained of God. The family is the most important social unit in time and in eternity. Under God’s great plan of happiness, families can be sealed in temples and be prepared to return to dwell in His holy presence forever. That is eternal life! It fulfills the deepest longings of the human soul—the natural yearning for endless association with beloved members of one’s family." 
(Elder Russell M. Nelson, Thanks Be To God, General Conference, Apr 2012)   

(3)   “The ultimate end of all activity in the Church is to see a husband and his wife and their children happy at home, protected by the principles and laws of the gospel, sealed safely in the covenants of the everlasting priesthood. Husbands and wives should understand that their first calling—from which they will never be released—is to one another and then to their children.” 
(President Boyd K. Packer, Cleansing the Inner Vessel, General Conference, October 2010) 

(4) "In the Church, we stress the significance of marriage, children, and the family because we know the doctrine. And we, as leaders of the Church, know that the adversary incessantly aims attacks at the family. In the past 50 years the birth rate has dropped in nearly every nation of the world. Marriages are being postponed until later in life, and families are getting smaller, even in the Church.
Our task to defend the family is not an easy one. Trends in the world diminish the significance of the family. Sadly, the sacred powers of procreation are desecrated by many people. And the divinely designed nature of marital intimacy is tarnished by the addictive, pernicious, and poisonous plague of pornography.
In reality, we are raising our children in enemy-occupied territory. The homes of our members must become the primary sanctuaries of our faith, where each can be safe from the sins of the world.
Our Master depends upon us to live according to His truth. Please teach our members that marriage is ordained of God. It is doctrinally based and eternally significant. "
(Elder Russell M. Nelson, The Doctrinal Importance of Marriage, Broadcast, Jan 2012) 

(5)  "We hope that when you attend meetings and see seemingly complete and happy families or hear someone speak of family ideals, you will feel glad to be part of a church that does focus on families and teaches of their central role in Heavenly Father’s plan for the happiness of His children; that in the midst of world calamity and moral decay, we have the doctrine, authority, ordinances, and covenants that do hold out the best hope for the world, including for the future happiness of your children and the families they will create." 
(Elder David S. Baxter, Faith, Fortitude, Fulfillment: A Massage to Single Parents, General Conference, Apr 2012)  

(6) "We see so many challenges today from distracting and destructive influences intended to mislead God’s children. We are seeing many young people who lack the deep spiritual roots necessary to remain standing in faith as storms of unbelief and despair swirl around them. Too many of our Father in Heaven’s children are being overcome by worldly desires. The onslaught of wickedness against our children is at once more subtle and more brazen than it has ever been. Teaching the gospel of Jesus Christ in the home adds another layer of insulation to protect our children from worldly influences. 
(Elder L. Tom Perry, Mothers Teaching Children in the Home, General Conference, April 2010) 
 
(7) "The creation of life is a great responsibility for a married couple. It is the challenge of mortality to be a worthy and responsible parent. Neither man nor woman can bear children alone. It was meant that children have two parents—both a father and a mother. No other pattern or process can replace this one." 
(President Boyd K. Packer, Cleansing the Inner Vessel, General Conference, October2010) 

(8)  “Marriage and family are ordained of God. The family is the most important social unit in time and in eternity.

(9) “Family time is sacred time and should be protected and respected. We urge our members to show devotion to their families.” 
(President Boyd K. Packer, Cleansing the Inner Vessel, General Conference, October 2010) 

(10) “Parents must resolve that teaching in the home is a most sacred and important responsibility. While other institutions, such as church and school, can assist parents to “train up a child in the way he [or she] should go” (Proverbs 22:6), ultimately this responsibility rests with parents. According to the great plan of happiness, it is parents who are entrusted with the care and development of our Heavenly Father’s children.” 
(Elder L. Tom Perry, Mothers Teaching Children in the Home, General Conference, April 2010)
