IX. That, even when God makes the greatest desolations by his judgments, he reserves some to be the monuments of his mercy, v. 22, 23. In Jerusalem itself, though marked for utter ruin, yet there shall be left a remnant, who shall not be cut off by any of those sore judgments before mentioned, but shall be carried into captivity, both sons and daughters, who shall be the seed of a new generation. The young ones, who had not grown up to such an obstinacy in sin as their fathers had who were therefore cut off as incurable, these shall be brought forth out of the ruins of Jerusalem by the victorious enemy, and behold they shall come forth to you that are in captivity, they shall make a virtue of a necessity, and shall come the more willingly to Babylon because so many of their friends have gone thither before them and are there ready to receive them; and, when they come, you shall see their ways and their doing; you shall hear them make a free and ingenuous confession of the sins they had formerly been guilty of, and a humble profession of repentance for them, with promises of reformation; and you shall see instances of their reformation, shall see what good their affliction has done them, and how prudently and patiently they conduct themselves under it. Their narrow escape shall have a good effect upon them; it shall change their temper and conversation, and make them new men. And this will redound, 1. To the satisfaction of their brethren: They shall comfort you when you see their ways. Note, It is a very comfortable sight to see people, when they are under the rod, repenting and humbling themselves, justifying God and accepting the punishment of their iniquity. When we sorrow (as we ought to do) for the afflictions of others, it is a great comfort to us in our sorrow to see them improving their afflictions and making a good use of them. When those captives told their friends how bad they had been, and how righteous God was in bringing these judgments upon them, it made them very easy, and helped to reconcile them to the calamities of Jerusalem, to the justice of God in punishing his own people so, and to the goodness of God, which now appeared to have had kind intentions in all; and thus "You shall be comforted concerning all the evil that I have brought upon Jerusalem, and, when you better understand the thing, shall not have such direful apprehensions concerning it as you have had." Note, It is a debt we owe to our brethren, if we have got good by our afflictions, to comfort them by letting them know it. 2. It will redound to the honour of God: "You shall know that I have not done without cause, not without a just provocation, and yet not without a gracious design, all that I have done in it." Note, When afflictions have done their work, and have accomplished that for which they were sent, then will appear the wisdom and goodness of God in sending them, and God will be not only justified, but glorified in them.
