Jesus Christ was in the garden beginning His prayer that he knew was going to lead Him into the events that was going to kill him.

As for us fathers, there will also come a time in our life when we will DIE!  If we are fortunate enough to have the time to 'look back' at our life, we will be able to see how we did as a father to our children.  Will we be disappointed or will be know that we did all that we could?  Will we be 'glorified' as a parent from our children?  Will God get the final glory from the raising of our children to serve him?...  or serve themselves?...  or to serve the world?

By the time we die, most of us fathers will have watched our children grow up and so we will have a pretty good idea of how we did as a parent.  Naturally, if we compare our own children to the world, we will probably figure our children are doing well if they didn't go queer, didn't turn out to be a criminal, they have a job and family & are still with their first wife and come and visit us once in a while in the nursing home.

But when we compare our children's growth and present life to Biblical standards, we can see better how their relationship (if they have one) is with Jesus Christ.  We then will have a true awareness as to how we did as a parent.  After all, our children did belong to God at one time (Romans 4:8; 5:13)!  Did we make sure they maintained that family 'membership' when the time came (Romans 7:9)?  Did we train them to listen to their FATHER as they grew up so when eventually took those famous first steps out into the world, they were still listening to GOD the FATHER?

Will God say to us fathers and grandfathers ...Well done, good and faithful servant; thou hast been faithful over a few things, I will make thee ruler over many things: enter thou into the joy of thy lord. Matthew 25:23

In that process, parents are accountable for the actions of that child until the child is considered understanding enough to be held accountable on their own.   In the lips of him that hath understanding wisdom is found: but a rod is for the back of him that is void of understanding  Proverbs 10:13.  Naturally, that is a gradual process and is in effect, applicable at various times of the child's growth.

Beyond the physical & mental growth stages of a child, the spiritual stages of a child are in the hands of the parents as well.  The goal, as verse 3 states, is that they might know thee the only true God, and Jesus Christ, whom thou hast sent.  It would be a shame, amen, to raise our kids to be a 'great kid', a star in school, to get a good job and career and yet, by our actions and testimony, to teach them to ignore the Book - or to 'dump the stuff' as soon as they left home, etc.

What a waste of a life - to have lived all those years making money, working hard, sacrificing all that parents sacrifice, only to find out it was all a waste.
What a waste of life - to have lived all those years and find an empty Judgment Seat - very little, if any, rewards, crowns, etc. Nothing!
What a waste of life - to have done so much good for others, to have given money to so many people, to have helped out so many people in their times of need, to have been a comfort to so many hurting people, to have been a teacher to hundreds of people in your lifetime, to have heard about God and Jesus Christ and the Word of God - only to find out that you did not know Jesus Christ as your Saviour.
