His mother had been careful to make him aware of that

From Across Five Aprils by Irene Hunt (chapter 4):

Suffering at the mercy of the elements was accepted by Jethro as being quite as natural as the hunger for green vegetables and fresh fruit that was always with him during the winter. When one found comfort, he was grateful, but he was never such a fool as to expect a great deal of it. The hardships one endured had a purpose. His mother had been careful to make him aware of that.

as full of reason as it is of wonder

From The Princess and Curdie by George MacDonald (chapter 4):

I suspect there is nothing a man can be so grateful for as that to which he has the most right.

…But the story of the evening was too solemn for Curdie to come out with all at once. He must wait until they had had their porridge, and the affairs of this world were over for the day.

…They were the happiest couple in that country, because they always understood each other, and that was because they always meant the same thing, and that was because they always loved what was fair and true and right better, not than anything else, but than everything else put together.

…It is not for me to say whether you were dreaming or not if you are doubtful of it yourself; but it doesn’t make me think I am dreaming when in the summer I hold in my hand the bunch of sweet peas that make my heart glad with their colour and scent, and remember the dry, withered-looking little thing I dibbled into the hole in the same spot in the spring. I only think how wonderful and lovely it all is. It seems just as full of reason as it is of wonder. How it is done I can’t tell, only there it is! And there is this in it, too, Curdie—of which you would not be so ready to think—that when you come home to your father and mother, and they find you behaving more like a dear, good son than you have behaved for a long time, they at least are not likely to think you were only dreaming.
