Only right theology can lead to right worship and right obedience. Every church should strive to believe and confess and live in light of a truly biblical theology and sound doctrine. This study looks at why biblical theology is important, and then shows participants how biblical theology can fuel their love, holiness, worship, witness, and unity. A series of ten 6–7 week studies covering the nine distinctives of a healthy church as originally laid out in Nine Marks of a Healthy Church by Mark Dever. This series explores the biblical foundations of key aspects of the church, helping Christians to live out those realities as members of a local body. Conveniently packaged and accessibly written, the format of this series is guided, inductive discussion of Scripture passages and is ideal for use in Sunday school, church-wide studies, or small group contexts.
