Christian, Muslim or Jewish... men who are fathers have the responsibility for learning their own faith and teaching it to their children, from the earliest age. Women cannot be trusted to do this, especially nowadays as they are too "busy" and self absorbed. Once women started caring only about their "self actualization" and "liberation" and "progressiveness," they stopped caring about God or their children.
One sure sign of being a man is one who is secure and knowledgeable in his faith, and who takes responsibility for teaching it to his children.
Proverbs 2: 11
My son, if you receive my words and treasure my commands, turning your ear to wisdom, inclining your heart to understanding; yes, if you call to intelligence, and to understanding raise your voice; if you seek her like silver, and like hidden treasures search her out; then will you understand the fear of the Lord; the knowledge of God you will find; for the Lord gives wisdom, from his mouth comes knowledge and understanding; he has counsel in store for the upright, he is the shield of those who walk honestly, guarding the paths of justice, protecting the way of his pious ones.
Then you will understand rectitude and justice, honesty, every good path; for wisdom will enter your heart, knowledge will please your soul, discretion will watch over you, understanding will guard you.
Proverbs 22: 6
Train a boy in the way he should go;
even when he is old, he will not swerve from it.
Proverbs 23: 15-18
My son, if your heart be wise, my own heart will also rejoice; and my inmost being will exult, when your lips speak what is right.
Let not your heart emulate sinners, but be zealous for the fear of the Lord always; for you will surely have a future, and your hope will not be cut off.
