We believe God has revealed himself in the Bible, which consists solely of the 66 books of the Old and New Testaments. Every word was inspired by God through human authors, so that the Bible as originally given is in its entirety the Word of God, without error and fully reliable in fact and doctrine. It is a perfect treasure of heavenly instruction and reveals the principles by which God will judge us. The Bible alone speaks with final authority and is always sufficient for all matters of belief and practice.
