Joshua 4:24

That all the people of the earth might know - It is very likely that כל עמי הארץ col ammey haarets means simply, all the people of this land - all the Canaanitish nations, to whom, by the miracles wrought in behalf of his people, he intended to show his eternal power and Godhead, the excellence of his protection, and the unavailableness of human might against his omnipotence; and the miracles he wrought for this people, in the sight of the heathen, were well calculated to make these things known.

1. God intends that his religion should be maintained and propagated in the earth; therefore he has given a revelation of himself to men, that it may be taught in the world; and he particularly requires that parents should be diligent and fervent in teaching their children the knowledge of his name.

2. This is one great use of the ordinances of the Gospel, and the rites of religion. They are all significators of sacred things, and point out matters of infinite importance beyond themselves.

3. A spirit of inquiry is common to every child: the human heart is ever panting after knowledge; and if not rightly directed when young, will, like that of our first mother, go astray after forbidden science.

4. If we wish our children to be happy we should show them where happiness is to be found. If we wish them to be wise, we should lead them unto God by means of his word and ordinances. It is natural for a child to inquire, "What do you mean by this baptism? - by this sacrament? - by praying - by singing psalms and hymns?" etc. And what fine opportunities do such questions give pious and intelligent parents to instruct their children in every article of the Christian faith, and in every fact on which these articles are established! Oh why is this neglected, while the command of God is before our eyes, and the importance of the measure so strikingly obvious?
