What is something else every believer ought to know?  That the Bible IS the word of God.  "All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be omplete, thoroughly equipped for every good work." -2 Timothy 3:16-17.  It is historically accurate, unified, has fulfilled prophecies, eternal, and transforming! -Pastor Mike
