When Christians speak of the authority of Scripture, because Christians believe that this word, even though it's mediated through many different human authors, nevertheless is God breathed and is revealed by God and is utterly reliable and all that it says, with all of its different literary genres, it's trustworthy and without mistake or distortion. It is trustworthy and therefore, because it is from God it has God's authority.
D. A. CarsonThe notion of the enduring authority focuses on the fact that some people think that notions like authority of Scripture's is passé, while others say that the present configuration of the doctrine of inerrancy is a late addition. And to both we want to say, No we're talking about the enduring authority of Scripture, grounded first and foremost in its relevatory status, something given by God and utterly reliable.
D. A. CarsonJesus is hungry but feeds others; He grows weary but offers others rest; He is the King Messiah but pays tribute; He is called the devil but casts out demons; He dies the death of a sinner but comes to save His people from their sins; He is sold for thirty pieces of silver but gives His life a ransom for many; He will not turn stones to bread for Himself but gives His own body as bread for people.
