Basically Baptists have considered the Bible as authoritative for faith and practice because of its very nature. Baptists have insisted that the divine nature of the Bible is the basis of its authority. No other writing compares to the Bible. The Bible stands alone among all other writings in that it is uniquely from God and about God.
For much of our history, Baptists have simply accepted the authority of the Bible based on belief in its divine nature. Scriptures were quoted to validate Baptist beliefs and practices without much effort to “prove” the divine nature of the Bible.
However, Baptists and others can point to many evidences of the divine, authoritative nature of the Bible, such as the amazing unity of the Bible in spite of the fact that it was written by a variety of persons over hundreds of years, the fulfillment of Old Testament prophecies such as in the life and teachings of Jesus, the continuing relevance of the Bible’s message over centuries, the power of its message to transform lives and society, and the repeated claims within the Bible to be the word of God.
