“But yet, since He knew that it would be good, He created both angels and men free to do that which is righteous, and He appointed periods of time during which He knew it would be good for them to have the exercise of free-will; and because He likewise knew it would be good, He made general and particular judgments; each one’s freedom of will, however, being guarded.”
Dialogue with Trypho, chapter CII. In ANF1, that is, Roberts A, Donaldson J and Coxe AC (1885) Ante-Nicene Fathers, Vol 1. [Cf chapter LXXXVIII.]

The Life and Adventures of Santa Claus (1902)
Context: And, afterward, when a child was naughty or disobedient, its mother would say:
"You must pray to the good Santa Claus for forgiveness. He does not like naughty children, and, unless you repent, he will bring you no more pretty toys."But Santa Claus himself would not have approved this speech. He brought toys to the children because they were little and helpless, and because he loved them. He knew that the best of children were sometimes naughty, and that the naughty ones were often good. It is the way with children, the world over, and he would not have changed their natures had he possessed the power to do so.
