The popular worship song "God of This City" was written by Aaron Boyd, lead singer of Bluetree, while they were on a mission trip to Thailand. Near the end of a gig in a bar beneath a brothel in one of the worldrs"s sex-trade capitals, Aaron began to sing to the city that "greater things are yet to come / greater things are still to be done in this city." Within a few days, the full lyrics had emerged; within a few months, the song was ringing in Bluetreers"s hometown of Belfast, where the promise of "greater things" is starting to bear fruit. "God of This City" eventually became the anthem of the Passion international worship conferences, but there is more to the song than an inspiring melody and unusual history. In God of This City, the book, Aaron Boyd unpacks the lyrics of the song, and along the way shares his thoughts on the state of the Church, the persistent injustice in the world and the biblical mandate to right the wrongs done to our global neighbors. Many local churches and ministries have taken "God of This City" as a rallying cry for their own communities, and the book is a further challenge for the Body of Christ to be an agent of His change-living lives of worship marked by actions of justice in a world longing for greater things.
