The Bible holds supreme authority by virtue of its Author, who is the King of creation and thus Ruler over all the earth. The Bible’s authority is inherent in its every word. Scripture is God’s revelation in history. Just as there is no higher authority in an earthly kingdom than a king – there is no higher authority you and I can appeal to than the Word of God in God’s kingdom.
