Jeremiah 30:20

The meaning is, that though the kingdom would through a dreadful ruin become extinct, together with all its dignity, the Jews would yet, through Christ, recover what they had lost through their sins, ingratitude, and perverseness.

He afterwards adds, His seed shall be established before my face, and I will visit all his oppressors Here again God confirms the promise concerning the perpetuity of his Church. He therefore says that the assembly of the people would be established before him, by which words he bids the Jews to look upwards, for in the world nothing was to be found but despair. God then calls the attention of the Jews to himself, when he says that the Church would be established before his face. And as the power of enemies was so great, that the faithful might justly object and say, that every avenue was closed up against God’s favor, he adds, that God on the other hand had sufficient power to destroy and to reduce to nothing all their enemies; and he mentions all, because the Chaldean monarchy was widely extended and consisted of many nations; and there was no part of it which was not most hostile to the Jews. As, then, the miserable exiles saw that not only the Chaldeans were inimical to them, but also other nations, so that they were hated almost by the whole world, God here comes to their aid, and declares that he had power enough to destroy all their enemies.

A useful doctrine may be hence deduced: The Church was in such a manner perpetual, that its condition was yet variable; for it often seemed good to God to break off the course of his favor before the coming of Christ. What then happened we may accommodate to our own time. As, then, the Prophet says here, that the children of the Church would be as at the beginning, we need not wonder when the Church happens at any time to be scattered, as indeed the case was under the Papacy. For the Church was not only dead, but also buried, and was not only as a putrid carcase, but like the dust it had wholly vanished; for what remnants could have been found fifty years ago? We hence see that what happened under the Law has also taken place under the kingdom of Christ; for the Church has sometimes been overwhelmed with troubles, and has been hid without any glory or beauty. But, in the meantime, we embrace this promise, that the children of the godly shall be as formerly; for as the kingdom of Christ in former times flourished, so we ought to feel assured that there is sufficient power in God to restore to the Church its glory, so that Christ’s kingdom may again rise up, and all God’s blessings shine forth in it. But as many enemies surround the Church on every side, and the Devil ever excites everywhere commotions and disturbances, let us know that there is another clause added, even that God will be the defender of his people; so that how much soever the whole world may attempt to tread under foot his favor, he will yet not suffer them to accomplish their fury; for he has the power not only to restrain their assaults, but also wholly to destroy them and to obliterate their memory; for this is what is implied in the word visiting. It then follows —
