In proportion as we keep ourselves fully alive to our tendency in this matter of authority may we trust ourselves to administer the law to creatures so tender in body and soul as are the little children. We shall remember that a word may wound, that a look may strike as a blow. It may indeed be necessary to wound in order to heal, but we shall examine ourselves well before we use the knife. There will be no hasty dealing out of reproof and punishment, reward and praise, according to the manner of mood we are in. We shall not only be aware that our own authority is deputed, and to be used with the meekness of wisdom; but we shall be infinitely careful in our choice of the persons in whose charge we place our children. It is not enough that they be good Christian people. We all know good Christian persons of an arbitrary turn who venture to wield that rod of iron which is safe in the hands of One alone. Let them be good Christian persons of culture and self-knowledge, not the morbid self-knowledge that comes of introspection, but that far wider, humbler cognisance of self that comes of a study of the guiding principles and springs of action common to us all as human beings, and which brings with it the certainty that--“I am just such an one as the rest, might even be as the worst, were it not for the grace of God and careful walking.” It is no doubt much easier to lay down our authority and let the children follow their own lead, or be kept in order by another, than to exercise constant watchfulness in the exercise of our calling. But this is not in our option; we must _rule_ with diligence. It is necessary for the children that we should; but we must keep ourselves continually in check, and see that our innate love of power finds lawful outlet in the building up of a child’s character, and not in the rude rebuff, the jibe and sneer, the short answer and hasty slap which none of us older people could conceivably endure ourselves, and yet practise freely on the children “for their good.”
