Joel 3:1

We have often heard of the year of the redeemed, and the year of recompences for the controversy of Zion; now here we have a description of the transactions of that year, and a prophecy of what shall be done when it comes, whenever it comes, for it comes often, and at the end of time it will come once for all. I. It shall be the year of the redeemed, for God will bring again the captivity of Judah and Jerusalem, Joe 3:1. Though the bondage of God's people may be grievous and very long, yet it shall not be everlasting. That in Egypt ended at length in their deliverance into the glorious liberty of the children of God. Let my son go, the he may serve me. That in Babylon shall likewise end well. And the Lord Jesus will provide for the effectual redemption of poor enslaved souls from under the dominion of sin and Satan, and will proclaim that acceptable year, the year of jubilee, the release of debts and servants, and the opening of the prison to those that were bound. There is a day, there is a time, fixed for the bringing again of the captivity of God's children, for the redeeming of them from the power of the grave; and it shall be the last day and the end of all time. II. It shall be the year of recompences for the controversy of Zion.
