The second key word to happiness is FAITH:
Faith, in all its aspects trust, confidence, and reliance brings happiness. If a home is to be happy parents must conduct themselves in such a way that they can have implicit faith in each other and inspire such faith also in their children.
The basis of such mutual trust, however, is a faith in God and in all the attributes we associate with Him truth, integrity, fairness, compassion, mercy.
If parents by their lives show their loyalty to God and his nature, they instinctively win the confidence of their children, and children likewise hold the confidence of their parents. They believe in one another.
