Jane Austen,  Mansfield Park:

Here had been grievous mismanagement; but, bad as it was, he gradually grew to feel that it had not been the most direful mistake in his plan of education. Something must have been wanting within, or time would have worn away much of its ill effect. He feared that principle, active principle, had been wanting; that they had never been properly taught to govern their inclinations and tempers by that sense of duty which can alone suffice. They had been instructed theoretically in their religion, but never required to bring it into daily practice. To be distinguished for elegance and accomplishments, the authorised object of their youth, could have had no useful influence that way, no moral effect on the mind. He had meant them to be good, but his cares had been directed to the understanding and manners, not the disposition; and of the necessity of self–denial and humility, he feared they had never heard from any lips that could profit them.

Bitterly did he deplore a deficiency which now he could scarcely comprehend to have been possible. Wretchedly did he feel, that with all the cost and care of an anxious and expensive education, he had brought up his daughters without their understanding their first duties, or his being acquainted with their character and temper.

Marilynne Robinson, Gilead:

That is how life goes–we send our children into the wilderness. Some of them on the day they are born, it seems, for all the help we can give them. Some of them seem to be a kind of wilderness unto themselves. But there must be angels there, too, and springs of water. Even that wilderness, the very habitation of jackals, is the Lord’s.

A parenthetical reflection:

Psalm 139: 16-18
Your eyes saw my unformed substance;
in your book were written, every one of them,
the days that were formed for me, when as yet there was none of them.
How precious to me are your thoughts, O God!
How vast is the sum of them!
If I would count them, they are more than the sand.
I awake, and I am still with you.
