Every Christian family ought to be as it were a little church, consecrated to Christ, and wholly influenced and governed by his rules. And family education and order are some of the chief means of grace. If these fail, all other means are likely to prove in effectual. If these are duly maintained, all the means of grace will be likely to prosper and be successful. Let me now therefore, once more, before I finally cease to speak to this congregation, repeat, and earnestly press the counsel which I have often urged on the heads of families, while I was their pastor, to great painfulness in teaching, warning, and directing their children; bringing them up in the training and admonition of the Lord; beginning early, where there is yet opportunity, and maintaining constant diligence in labors of this kind.
Remember that, as you would not have all your instructions and counsels ineffectual, there must be government as well as instructions, which must be maintained with an even hand, and steady resolution, as a guard to the religion and morals of your family, and the support of its good order. Take heed that it not be with any of you as it was with Eli of old, who reproved his children, but restrained them not; and that, by this means, you do not bring the like curse on your families as he did on his.
~ Jonathan Edwards
