3. They must put them in the way of making a good use of these works of wonder, the knowledge whereof was thus carefully transmitted to them, v. 24. (1.) The power of God was hereby magnified. All the world was or might be convinced that the hand of the Lord is mighty, that nothing is too hard for God to do; nor can any power, no, not that of nature itself, obstruct what God will effect. The deliverances of God's people are instructions to all people, and fair warnings not to contend with Omnipotence. (2.) The people of God were engaged and encouraged to persevere in his service "That you might fear the Lord your God, and consequently do your duty to him, and this for ever," or all days (margin), "every day, all the days of your lives, and your seed throughout your generations." The remembrance of this wonderful work should effectually restrain them from the worship of other gods, and constrain them to abide and abound in the service of their own God. Note, In all the instructions and informations parents give their children, they should have this chiefly in their eye, to teach and engage them to fear God for ever. Serious godliness is the best learning.
