SECOND LONDON BAPTIST CONFESSION OF FAITH 1.4-1.5
The authority of the Holy Scriptures obligates belief in them. This authority does not depend on the testimony of any person or church but on God the author alone, who is truth itself. Therefore, the Scriptures are to be received because they are the Word of God.
The testimony of the church of God may stir and persuade us to adopt a high and reverent respect for the Holy Scriptures. Moreover, the heavenliness of the contents, the power of the system of truth, the majesty of the style, the harmony of all the parts, the central focus on giving all glory to God, the full revelation of the only way of salvation, and many other incomparable qualities and complete perfections, all provide abundant evidence that the Scriptures are the Word of God. Even so, our full persuasion and assurance of the infallible truth and divine authority of the Scriptures comes from the internal work of the Holy Spirit bearing witness by and with the Word in our hearts.
