How do we know the Bible is the rule of faith?

In Luke 10:26-27, Jesus emphasizes the Scriptures as the foundation for faith and practice when He references the law concerning eternal life. This establishes the principle that the Bible is our sole authority in matters of faith, dismissing other human traditions and teachings. J.C. Ryle underlines the importance of measuring all religious claims against the Scriptures, asserting that anything not found in the Bible should be rejected. Thus, the Word of God serves as the ultimate guide for all belief and conduct.
