I read a sermon by Charles Spurgeon and this quote jumped off the page:
I trust you will never give up that excellent puritanical habit of catechising your children at home. Any father or mother who entirely gives up a child to the teaching of another has made a mistake. There is no teacher who wishes to absolve a parent from what he ought to do himself. He is an assistant, but he was never intended to be a substitute. Teach your children; bring up your old catechisms again, for they are after all blessed means of instruction, and the next generation shall outstrip those that have gone before it; for the reason why many of you are weak in the faith is this, you did not receive instruction in your youth in the great things of the gospel of Christ. If you had, you would have been so grounded, and settled, and firm in the faith, that nothing could by any means have moved you. I beseech you, then, understand truth, and then you will be more likely to hold fast by it. -Charles Spurgeon
(catechise: to instruct by asking questions, receiving answers, and offering explanations and corrections)
