Sunday worship isn't just about drawing near to God as an individual - it's about praising God together with his people. Christians "worship" God at church every week, but many don't know exactly what worship is or why they do it. For some, it's a warm-up for the sermon. For others, worship is a "me-and-Jesus" moment. But what is the biblically informed way to view corporate worship? In this addition to the 9Marks Building Healthy Churches series, Matt Merker explores the Bible's teaching about corporate worship as an activity in which God gathers the church by his grace, unto his glory, for his people's mutual good, and before the world's gaze. This book offers a biblical and theological perspective on this often misunderstood topic so believers can participate in gathered worship that is God-centered and mutually edifying, rather than for self-fulfillment.
