The Scriptures are essential because they are necessary to truly know, serve, enjoy, and glorify God. Human reason, intuition, religious experience, and general revelation through creation are insufficient and fatally defective due to sin's blinding effects on the mind. Only the Bible provides the sufficient, certain, and infallible rule for faith and practice, equipping believers for salvation and every good work. It serves as the presuppositional foundation of all reality, beginning with "In the beginning God", and enables true knowledge of God, ourselves, and how to live for His glory. Without Scripture, our understanding of God and life remains seriously flawed; with it, we gain the revelation needed for reconciliation to God and alignment with His truth.
