How do we know Sola Scriptura is true?

The doctrine of Sola Scriptura is rooted in the truth of Scripture itself, particularly in passages like 2 Timothy 3:16-17. Here, the Apostle Paul emphasizes that all Scripture is inspired by God and is profitable for equipping the believer for every good work. This inherent ability of the Scriptures to complete and equip believers underscores the principle that Scripture alone is sufficient and authoritative. Additionally, historical practices within the early church, as illustrated in Acts 17, demonstrate how the apostles consistently validated their teachings by reference to Scripture, highlighting the precedent for prioritizing the Word of God over all other authorities.
