Proverbs 27:11 (ESV)

11 Be wise, my son, and make my heart glad, that I may answer him who reproaches me.

Here is another word for both parents and children. Christian parents should be glad above all not that their children grow to become rich, famous, and successful, but rather that they grow to be wise, knowing and loving the Lord, and making his grace their own. In countless ways we should communicate this to our children. Likewise, children of believers should know that the aim and prayer of their parents is that their children grow in godliness. Adopting and pursuing this aim will lead to gladness and freedom from reproach for the children and their parents.
