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. CarsonOthers have questions about how it is that God and human beings can both be speaking through the one document such that you can see and read the personalities of the human authors with their individual vocabularies and literary genres, and yet this is nevertheless the word of God. How can that be? This is quite a contrast with Islam, for example, which holds that the Koran has been dictated in Arabic by God and as a result Mohammed is nothing more than the one who memorizes the word so as to pass it on. There is nothing of human contribution.
D. A. Carson"Study Bible" is the expression used for Bibles that include significant explanatory notes, usually at the bottom of the page, sometimes in the margins. Often a Study Bible will also include some brief articles, photographs of geographical and archaeological sites, fairly extensive maps, and charts that summarize a lot of information.
