Charles Spurgeon Commentary Deuteronomy 6:1-2

"Now this is the commandment, the statutes, and the ordinances, which Jehovah your God commanded to teach you, that ye might do them in the land whither ye go over to possess it; that thou mightest fear Jehovah thy God, to keep all his statutes and his commandments, which I command thee, thou, and thy son, and thy son`s son, all the days of thy life; and that thy days may be prolonged." — Deuteronomy 6:1-2 (ASV)

Now these are the commandments, the statutes, and the judgments, which the LORD your God commanded to teach you, that you might do them in the land where you go to possess it: That you might fear the LORD your God, to keep all his statutes and his commandments, which I command you—you, and your son, and your son's son, all the days of your life; and that your days may be prolonged.

Obedience to God should arise from the fear of him, or from a holy awe of God felt in the heart, for all true religion must be heart work. It is not the bare action alone at which God looks, but at the motive—at the spirit which dictates it. Hence it is always stated, That you might fear the Lord your God, to keep all his statutes and his commandments. Neither are we to be content with keeping commands ourselves.

It is the duty of parents to seek the good of their children—to seek that their son and their son's son should walk in the ways of God all their lives. May God grant us never to be partakers of the spirit of those who think that they have no need to look after the religion of their children—who seem as if they left it to a blind fate. May we care for them with this specific care—that our son and our son's son should walk before the Lord all the days of their life.
