This sermon presents a compelling case for studying the Westminster Confession of Faith as a systematic guide to understanding Scripture, not as a replacement for the Bible but as a tool to deepen biblical literacy and theological coherence. It emphasizes that systematic theology—organizing biblical truths around doctrinal themes such as Scripture, God, creation, sin, Christ, salvation, and eschatology—helps believers grasp the Bible's unified message across its 66 books. The Confession is defended as a historically tested, scripture-grounded, and globally shared summary of Reformed faith, with thousands of scriptural references, that aids in discerning sound doctrine amid distortion and error. By engaging the Confession with open Bibles and critical hearts, the church seeks to grow in knowledge, worship, and love for God, ensuring that theology shapes both mind and heart in faithful obedience to Scripture.
