That the generation to come might know them. That they might set their hope in God (Psalm 78:6-7).
That the generation to come might know them.
In this verse, the Psalmist confirms what he had said concerning the continued transmission of divine truth. It greatly concerns us to know, that the law was given not for one age only; but that the fathers should transmit it to their children, as if it were their rightful inheritance, in order that it might never be lost, but be preserved to the end of the world. This is the reason why Paul, in 1 Timothy 3:15, asserts that the church is the pillar and ground of the truth; by which he does not mean that the truth of itself is weak, and stands in need of foreign supports, but that God extends and diffuses it by the instrumentality of his ministers, who when they faithfully execute the office of teaching with which they are invested, sustain the truth, as it were, upon their shoulders. Now, the prophet teaches us, that it is our bounden duty to use our endeavors that there may be a continual succession of persons to communicate instruction in divine truth. It is said of Abraham before the law was written, Genesis 18:19, I know him, that he will command his children and his household after him, and they shall keep the way of the Lord to do justice and judgment, and after his death, this was enjoined upon the patriarchs as a necessary part of their duty. No sooner was the law delivered, than God appointed priests in His Church to be public masters and teachers. He has also testified by the prophet Isaiah, that the same is to be observed under the New Testament dispensation, saying, My Spirit that is upon thee, and my words which I have put in thy mouth, shall not depart out of thy mouth, nor out of the mouth of thy seed, nor out of the mouth of thy seeds seed, from henceforth and for ever (Isaiah 59:21).
In the passage before us, however, a particular injunction is given to the fathers on this point - each of them is enjoined diligently to instruct his own children, and all without distinction are taught, that their exertions in transmitting the name of God to their posterity will be most acceptable to Him, and receive His highest approbation.
By the words, that the children to be born should arise, is not denoted a small number of individuals; but it is intimated, that the preachers of divine truth, by whose efforts pure religion may flourish and prevail for ever, will be as numerous as those who are born into the world.
That they might set their hope in God.
Here the Psalmist points out the use to which the doctrine which he had stated should be applied. In the first place, the fathers, when they find that on the one hand they are instrumental in maintaining the pure worship of God. and that on the other, they are the means of providing for the salvation of their children, should, by such a precious result of their labors, be the more powerfully stirred up to instruct their children. In the second place, the children on their part being inflamed with greater zeal, should eagerly press forward in the acquisition of divine knowledge, and not suffer their minds to wander in vain speculations, but should aim at, or keep their eyes directed to, the right mark. It is unhappy and wretched toil to be ever learning, and never able to come to the knowledge of the truth (2 Timothy 3:7.).
When, therefore, we hear for what purpose the law was given, we may easily learn what is the true and most successful method of deriving benefit from it. The inspired writer places truth first, assigning it the highest rank. He then requires the observance of the holy commandments of God; and he puts in the middle the remembrance of the works of God, which serves to confirm and strengthen faith. In short, what he means is, that the sum of heavenly wisdom consists in this, that men, having their hearts fixed on God by a true and unfeigned faith, call upon Him, and that, for the purpose of maintaining and cherishing their confidence in Him, they exercise themselves in meditating in good earnest upon his benefits; and that then they yield to Him an unfeigned and devoted obedience. We may learn from this, that the true service of God begins with faith. If we transfer our trust and confidence to any other object, we defraud him of the chief part of his honor.
