8 Joshua son of Nun, the servant of the LORD, died at the age of a hundred and ten. And they buried him in the land of his inheritance, at Timnath Heres in the hill country of Ephraim, north of Mount Gaash. After that whole generation had been gathered to their fathers, another generation grew up, who knew neither the LORD nor what he had done for Israel. From all outward signs, they only may have told their children about the Lord, but the children obviously didn't come to believe. Today we see the same thing happening.
Parents wonder why their children act the way they do.
The children obviously hear what the parents say, but more importantly they see what their parents do, and the two are most often something different. The problem is that these parents never gave their children the insight to follow their true leader, the Lord their God. They were never given the opportunity to come to know the Lord along with their parents. If parents don't go to church, the children don't think it's necessary either, and thus they drift further away from the Lord, and their heart is set only upon following the ways of the world. All too soon they completely lose sight of the true standard they are to be following.
