Failure to believe stems from moral failure to recognize the truth, not from want of evidence, but from willful neglect or distortion of the evidence.
D. A. CarsonWhen 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. CarsonFor example, the Bible does say this is a proposition, "There is no God." But of course the context of Psalm 14:1 enriches it a bit: "the fool has said in his heart, there is no God." So there are contextual constraints and when you finish putting in all the contextual constraints and sophisticated discussions of what inerrancy is and isn't.
