Psalm 87, predicts the conversion of all nations to Christ under the beautiful picture of their birth in Zion. The writer celebrates the glory of the church, as the means of spiritual blessing to the nations, exclusively from Jerusalem. Zion is a type or picture of the gospel-church. This psalm reminds us that Zion—the city of God, the people of God—will be made up of every tribe and tongue and nation. This song reminds us of the coming conversion of the nations and of their incorporation into the Book of Life and points us to something of God’s choosing love. It reminds us of how glorious the church is in God’s eyes and why.
