Self-accusation before God is something that is very necessary for us; and humility of heart is extremely advantageous in our lives, above all at the time of prayer. For prayer requires great attention and needs a proper awareness, otherwise it will turn out to be unacceptable and rejected, and `it will be turned back empty' to our bosom.
Many teach their children about worldly politics, others teach them to speak foreign languages: French, German, Italian, and in this spend no trifling sums. Others endeavor to teach them commerce and other arts. But hardly anyone teaches them to live in a Christian manner. However, without this, all learning is nothing and all wisdom is madness. For what does it profit a Christian to speak Italian, French and German, if he lives in an ungodly manner? What use is it to be skilled in commerce and the arts if one lacks the fear of God? God will not ask you whether you taught your children French, German or Italian or the politics of social life--but you will not escape divine reprobation for not having instilled goodness into them. I speak plainly but I tell the truth: if your children are bad, your grandchildren will be worse, and the evil will thus increase...and the root of all this is our thoroughly bad education.
Parents and teachers! Beware and be most careful not to let your children be capricious; otherwise they will soon forget to value your love: their hearts will be corrupted with wickedness; they will soon lose holy, true, glowing love from their hearts, and, on reaching maturity, they will complain bitterly that in their youth you spoilt them too much and encouraged them in their caprices. Capriciousness is the germ of the corruption of the heart, the rust of the heart, the moth of love, the seed of evil, and an abomination to the Lord.
As for uprooting your passions, begin with self-reproach and with awareness of your own weaknesses; and consider yourself to be deserving of afflictions.
The first duty of a Christian, of a disciple and follower of Jesus Christ, is to deny oneself. To deny oneself means to give up one's bad habits, to root out of the heart all that ties us to the world; not to cherish bad desires and thoughts; to quench and suppress bad thoughts; to avoid occasions of sin; not to do or desire anything from self-love but to do everything out of love for God. To deny oneself means, according to the Apostle Paul, to be dead to sin and the world, but alive to God.
Have great care of your children. We live at a time when much freedom is given to the expression of thought, but little care is taken that thoughts should be founded on truth. Teach them to love truth.
Among the virtues which must be instilled in a child's heart with special persistence, an important and fundamental place belongs to truthfulness, that is to say, a feeling of love for truth and an aversion towards falsehood. After obedience, this virtue should be given second place. If falsehood is the root of all sin, truth is the beginning and foundation for nearly all virtues, and for this reason parents must direct their attention primarily at nurturing truthfulness in children.
