A Concise Summary of Biblical Truth by John MacArthur Doctrine not only equips you with more knowledge about God, it also shapes your affections toward him and directs your actions for him—but it can be difficult to know where to begin. This concise handbook, developed from John MacArthur’s larger work Biblical Doctrine, is an entry point for studying theological topics such as the Bible, the Holy Spirit, the church, and more. As MacArthur walks through the essentials of the Christian faith doctrine by doctrine, he’ll not only encourage your heart and mind, but also empower you to proclaim the faith that was “once for all delivered to the saints” (Jude 3).
