30:19-26 God's people will soon arrive at the Zion above, and then they will weep no more for ever. Even now they would have more comfort, as well as holiness, if they were more constant in prayer. A famine of bread is not so great a judgment as a famine of the word of God. There are right-hand and left-hand errors; the tempter is busy courting us into by-paths. It is happy if, by the counsels of a faithful minister or friend, or the checks of conscience, and the strivings of God the Spirit, we are set right when doubting, and prevented from going wrong. They shall be cured of their idolatry. To all true penitents sin becomes very hateful. This is shown daily in the conversion of souls, by the power of Divine grace, to the fear and love of God. Abundant means of grace, with the influences of the Holy Spirit, would be extended to places destitute of them. The effect of this should be comfort and joy to the people of God. Light, that is, knowledge, shall increase. This is the light which the gospel brought into the world, and which proclaims healing to the broken-hearted.
