Fathers: must provide Quality AND Quantity time

Effective family leadership, brethren, requires both quantity and quality time. The teaching and governance of the family must not be left to your wife alone, to society, to school, or even the Church.

You adult brethren, may I suggest an "I will" for us which has been repeatedly emphasized by modern prophets? It is of critical importance in today’s world, where the influence of the adversary is intensifying and the foundation of our society, the family, is disintegrating. It is I will resolve that the leadership of my family will be my most important and sacred responsibility; and I will not leave the teaching and governance of my family to society, to the school, or to the Church. We are reminded in the Doctrine and Covenants that fathers and mothers are held accountable by the Lord to teach their children about faith, repentance, baptism, the Holy Ghost, and the need to pray and walk uprightly before the Lord (see D&C 68:25, 28)
Perhaps you have heard some say, "I am so busy with living and providing that I have little time to devote to my family, but I make an effort to see that my limited time is quality time." Brethren, this type of rationalization is severely flawed. Effective family leadership requires both quantity and quality time.

Benson on public schools

"We should not assume that public schools always reinforce teachings given in the home concerning ethical and moral conduct. We have seen introduced into many school systems false ideas about the theory of man's development from lower forms of life, teachings that there are no absolute moral values, repudiation of all beliefs regarded as supernatural, permissiveness about sexual freedom that gives sanction to immoral behavior and "alternative life-styles" such as lesbianism, homosexuality, and other perverse practices. "Such teachings not only tend to undermine the faith and morals of our young people, but they deny the existence of God, who gave absolute laws, and the divinity of Jesus Christ. Surely we can see the moral contradiction of some who argue for the preservation of endangered species, but sanction the abortion of unborn humans.

There is a solution, and it is that the Lord expects great things from the fathers of Israel. Fathers must take time to find out what their children are being taught and then take steps to correct false information and teaching.

I know fathers who inquire of their children each evening to determine firsthand what their children are being taught in school and what needs to be corrected. Then, if necessary, they instruct them in what the Lord has revealed. This is application of the principle that `light and truth forsake that evil one.'" (D&C 93:37)
