We do not affirm the divine inspiration of the Bible in such as way as to deny or to minimise its human authorship. Geisler (Baker Encylopedia of Christian Apologetics) outlines this as follows:-
First, every book in the Bible was the composition of human writers.
Second, the Bible manifests different human literary styles, from the mournful meter of lamentations to the exalted poetry of Isaiah, from the simple grammar of John to the complex Greek of Hebrews. Their choices of metaphors show that different writers used their own background and interests. James is interested in nature. Jesus uses urban metaphors, and Hosea those of rural life.
Third, the Bible manifests human perspectives and emotions; David spoke in Psalm 23 from a shepherd’s perspective; Kings is written from a prophetic vantage point, and Chronicles from a priestly point of view; Acts manifests a historical interest and 2 Timothy a pastor’s heart. Paul expressed grief over the Israelites who had rejected God (Rom. 9:2).
Fourth, the Bible reveals human thought patterns and processes, including reasoning (Romans) and memory (1 Cor. 1:14-16).
Fifth, writers of the Bible used human sources for information, including historical research (Luke 1:1-4) and noncanonical writings (Josh. 10:13; Acts 17:28; 1 Cor. 15:33; Titus 1:12; Jude 9, 14).
