9:11-15 Christ died to gather together the children of God that were scattered abroad, here said to be those who were called by his name. The Lord saith this, who doeth this, who can do it, who has determined to do it, the power of whose grace is engaged for doing it. Verses 13-15 may refer to the early times of Christianity, but will receive a more glorious fulfilment in the events which all the prophets more or less foretold, and may be understood of the happy state when the fulness both of the Jews and the Gentiles come into the church. Let us continue earnest in prayer for the fulfilment of these prophecies, in the peace, purity, and the beauty of the church. God marvellously preserves his elect amidst the most fearful confusions and miseries. When all seems desperate, he wonderfully revives his church, and blesses her with all spiritual blessings in Christ Jesus. And great shall be the glory of that period, in which not one good thing promised shall remain unfulfilled.

Such shall be the abundance that the harvest and vintage can hardly be gathered before the time for preparing for the next crop shall come. Instead of the greater part of the year being spent in war, the whole shall be spent in sowing and reaping the fruits of earth. Compare Isa 65:21-23, as to the same period.

mountains … drop sweet wine—an appropriate image, as the vines in Palestine were trained on terraces at the sides of the hills.
