How do we know the importance of Scripture for salvation?

The Apostle Paul emphasizes the importance of Scripture in 2 Timothy 3:15, stating that the 'holy scriptures... are able to make thee wise unto salvation through faith which is in Christ Jesus.' This highlights that the Word of God is not just a historical document but serves a transformative purpose by guiding believers to recognize their need for salvation and directing them to Christ as the source of that salvation. Without the Scriptures, individuals would lack the foundational truths necessary for understanding God's plan of redemption.
