“Honour your father and your mother, that your days may be long upon the land which the Lord your God is giving you. “
An adult son or daughter, though independent, must honour his parents. Such behaviour gives long life and longer days to achieve much more.
Honour is to care, respect, and take pride in them and bring joy even through your own achievements. This keeps them healthy with a contented mindset.
The obedient attitude helps them also to adjust well in society and live a blessed life!
