2. What then? When God has gathered them out of their enemies' hands, and brought them home again, (1.) Then God will have the praise of it: I will be sanctified in them in the sight of many nations, v. 27. As God was reproached in the reproach they were under during their captivity, so he will be sanctified in their reformation and the making of them a holy people again, and will be glorified in their restoration and the making of them a happy glorious people again. (2.) Then they shall have the benefit of it (v. 28): They shall know that I am the Lord their God. Note, The providences of God concerning his people, that are designed for their good, have the grace of God going along with them to teach them to eye God as the Lord, and their God, in all; and then they do them good. They shall eye him as the Lord and their God, [1.] In their calamities, that it was he who caused them to be led into captivity; and therefore they must not only submit to his will, but endeavour to answer his end in it. [2.] In their comfort, that it is he who has gathered them to their own land, and left none of them among the heathen. Note, By the variety of events that befal us, if we look up to God in all, we may come to acquaint ourselves better with his various attributes and designs. (3.) Then God and they will never part, v. 29. [1.] God will pour out his Spirit upon them, to prevent their departures from him and returns to folly again, and to keep them close to their duty. And then, [2.] He will never hide his face any more from them, will never suspend his favour as he had done; he will never turn from doing them good, and, in order to that, he will effectually provide that they shall never turn from doing him service. Note, The indwelling of the Spirit is an infallible pledge of the continuance of God's favour. He will hide his face no more from those on whom he has poured out his Spirit. When therefore we pray that God would never cast us away from his presence we must as earnestly pray that, in order to that, he would never take his Holy Spirit away from us, Ps. li. 11.
