III. Let them know that God will set up a church for himself in the world, which shall be abundantly replenished in a little time (v. 7): Before she travailed she brought forth. This is to be applied in the type to the deliverance of the Jews out of their captivity in Babylon, which was brought about very easily and silently, without any pain or struggle, such as was when they were brought out of Egypt; that was done by might and power (Deut. iv. 34), but this by the Spirit of the Lord of hosts, Zech. iv. 6. The man-child of the deliverance is rejoiced in, and yet the mother was never in labour for it; before her pain came she was delivered. This is altogether surprising, uncommon, and without precedent, unless in the story which the Egyptian midwives told of the Hebrew women (Exod. i. 19), that they were lively and were delivered ere the midwives came in unto them. But shall the earth be made to bring forth her fruits in one day? No, it is the work of some weeks in the spring to renew the face of the earth and cover it with its products. Some read this to the same purport with the next clause, Shall a land be brought forth in one day, or shall a nation be born at once? Is it to be imagined that a woman at one birth should bring children sufficient to people a country and that they should in an instant grow up to maturity? No; something like this was done in the creation; but God has since rested from all such works, and leaves second causes to produce their effects gradually. Nihil facit per saltum—He does nothing abruptly. Yet, in this case, as soon as Zion travailed she brought forth. Cyrus's proclamation was no sooner issued out than the captives were formed into a body and were ready to make the best of their way to their own land. And the reason is given (v. 9), because it is the Lord's doing; he undertakes it whose work is perfect. If he bring to the birth in preparing his people for deliverance, he will cause to bring forth in the accomplishment of the deliverance. When every thing is ripe and ready for their release, and the number of their months is accomplished, so that the children are brought to the birth, shall not I then give strength to bring forth, but leave mother and babe to perish together in the most miserable case? How will this agree with the divine pity? Shall I begin a work and not go through with it? How will that agree with the divine power and perfection? Am I he that causes to bring forth (so the following clause may be read) and shall I restrain her? Does God cause mankind, and all the species of living creatures, to propagate, and replenish the earth, and will he restrain Zion? Will he not make her fruitful in a blessed offspring to replenish the church? Or, Am I he that begat, and should I restrain from bringing forth? Did God beget the deliverance in his purpose and promise, and will he not bring it forth in the accomplishment and performance of it? But this was a figure of the setting up of the Christian church in the world, and the replenishing of that family with children which was to be named from Jesus Christ. When the Spirit was poured out, and the gospel went forth from Zion, multitudes were converted in a little time and with little pains compared with the vast product. The apostles, even before they travailed, brought forth, and the children born to Christ were so numerous, and so suddenly and easily produced, that they were rather like the dew from the morning's womb than like the son from the mother's womb, Ps. cx. 3. The success of the gospel was astonishing; that light, like the morning, strangely diffused itself till it took hold even of the ends of the earth. Cities and nations were born at once to Christ. The same day that the Spirit was poured out there were 3000 souls added to the church. And, when this glorious work was once begun, it was carried on wonderfully, beyond what could be imagined, so mightily grew the word of God and prevailed. He that brought to the birth in conviction of sin caused to bring forth in a thorough conversion to God.
