Psalms 78:6

That the generation to come might know them
Not only notionally, but spiritually and experimentally; which is the case, when human teachings are attended with the spirit of wisdom and revertion in the knowledge of divine truths; for the truths of the Gospel are unknown to men; the Gospel is hidden wisdom, the wisdom of God in a mystery; the Bible is a sealed book, the doctrines of it are riddles and dark sayings; the ministry of the word is the means of knowledge, which become effectual when attended with the Spirit and power of God:

even the children which should be born, who should arise and declare
them to their children;
and so be transmitted from age to age: it is the will of God, that, besides private instructions, there should be a standing ministry kept up in all ages, to the end of the world; and he will have some that shall receive the Gospel, and profess his name; there has been and will be a succession of regenerate persons; instead of the fathers come up the children, a seed to serve the Lord, accounted to him for a generation; the seed and the seed's seed of the church, from whose mouth the word of God shall never depart; but they shall declare it one to another, by which means it shall be continued to the latest posterity, ( Psalms 22:30 Psalms 22:31 ) ( Isaiah 59:21 ) .
