Reconciliation of the children to the parents.
The duty of a parent is not to fulfill his or her own desires - it is to raise and admonish the next generation in the fear of the Lord. We have only to look at the state of America today to see that a selfish drive to fulfill one's self has left the last three generations without moral guidance and upbringing.
"Fathers, do not exasperate your children". The trust and respect of our children must be earned - it is not an automatic "right" of the parent. Our hypocrisies and failings are nearly invisible to us, but blindingly obvious to our children. If we say one thing and do another, we teach them to do the same.
Material things do not in any way make up for the loss of attention and love that sacrifice shows.
