Train (nuture, instruct, guide) A Child In The Way That He Should Go... It's not the schools, church, mosque, friends, etc responsibility. But yours and yours alone! They are God's heritage and you are only a steward.
Once a child is born, he becomes a member of the family he is born into. The parents has a responsibility to ensure that the child is well catered for in all aspects! As he grow up, he learns to fall and stand again. All of his life really is about this - learning to understand who he is. And parents have been saddled with thw duty to nuture, instruct and guide everyday!
