John Calvin Commentary Psalms 102:28

"The children of thy servants shall continue, And their seed shall be established before thee." — Psalms 102:28 (ASV)

The children of your servants shall dwell. By these words, the prophet suggests that he does not ask for the preservation of the Church because it is a part of the human race, but because God has raised it above the revolutions of the world. Undoubtedly, when He adopted us as His children, His design was to cherish us, as it were, in His own bosom. The inference of the inspired psalmist is not, therefore, far-fetched when, amid innumerable storms, each of which might carry us away, he hopes that the Church will have a permanent existence.

It is true that when, through our own fault, we become estranged from God, we are also, as it were, cut off from the fountain of life; but no sooner are we reconciled to Him than He begins again to pour down His blessings upon us. From this it follows that true believers, as they are regenerated by the incorruptible seed, will continue to live after death, because God continues unchangeably the same. By the word dwell, is meant an enduring and everlasting inheritance.

When it is said that the seed of God’s servants shall be established before His face, the meaning is that the salvation of true believers is secured not in the manner of the world, or according to the way in which the heavens and the earth are established, but because of the holy union that exists between them and God.

By the seed and children of the godly are meant not all their descendants without exception—for many who are descended from them according to the flesh degenerate—but those who do not turn aside from the faith of their parents. Successive generations are clearly indicated, because the covenant extends even to future ages, as we will again find in the subsequent psalm.

If we firmly keep the treasure of life entrusted to us, let us not hesitate, although we may be surrounded by innumerable deaths, to cast the anchor of our faith in heaven, so that the stability of our welfare may rest in God.
