Worship isn’t just something we do—it’s the purpose of our existence. Every week, Christians come together to share a taste of heaven itself, where all of God’s redeemed people will exalt His holy name forever. But what’s really going on when we worship? And what’s worship supposed to look like in the life of the church? In Let Us Worship God, Dr. Derek Thomas addresses the “how” and “why” of Christian worship. May we worship God however we want? Do we need the church, or can we worship alone? What are the necessary elements of a worship service? These and other questions find their answers in these pages, leading us to a greater understanding of worship as life’s highest privilege and richest joy. Dr. Derek W.H. Thomas is senior minister of the First Presbyterian Church in Columbia, S.C., and Chancellor’s Professor of Systematic and Pastoral Theology at Reformed Theological Seminary. He is a Ligonier Ministries teaching fellow and author of many books, including How the Gospel Brings Us All the Way Home, Calvin’s Teaching on Job, Strength for the Weary, and, with Dr. Sinclair B. Ferguson, Ichthus: Jesus Christ, God’s Son, the Saviour.
