Confusion abounds when trying to define the term "worship." Is it singing? A service? Something that encompasses all of life? Bringing biblical truth to bear on this critical issue, Mike Cosper, an experienced worship leader, argues that all true worship has one object (God), two contexts (the gathered church and the scattered church) and three audiences (God, the church, and the world). Writing from the conviction that the gospel is the heartbeat of true worship, Cosper explores four key practices (liturgy, song, style, and creativity), showing that worship is fundamental to spiritual formation. This eminently readable book, designed for church leaders and laypersons alike, offers a vibrant theology of worship that is biblical yet contextual, and systematic yet practical.
