In cases where the ordinary human personality and writing style of the author were prominently involved, as seems the case with the major part of Scripture, all that we are able to say is that God’s providential oversight and direction of the life of each author was such that their personalities, their backgrounds and training, their abilities to evaluate events in the world around them, their access to historical data, their judgment with regard to the accuracy of information, and their individual circumstances when they wrote, were all exactly what God wanted them to be, so that when they actually came to the point of putting pen to paper, the words were fully their own words but also fully the words that God wanted them to write, words that God would also claim as his own.
Judging by the various vocabulary, grammar, styles, figures of speech, and human interests of the various authors, God did not disregard the personality and culture of the biblical writers when He providentially guided them to be the vehicles through which He revealed His written Word to humankind. On the contrary, the Bible is a thoroughly human book in every respect, except that it is without error. Regardless of the mystery surrounding how God was able to make His word certain without the destroying the freedom and personality of the authors, several things are clear. The human authors of Scripture were not mere secretaries taking dictation; their freedom was not suspended or negated, and they were not automatons. What they wrote is what they desired to write in the style that they were accustomed to using. God in His providence engaged in a divine concurrence between their words and His so that what they said, He said.
God formed the personality of the writer. God made [him] into the man He wanted him to be. God controlled his heredity and his environment. When the writer reached the point that God intended, God directed and controlled the free choice of the man so that he wrote down the very words of God. God literally selected the words of each author’s own life, out of his personality, his vocabulary, and his emotions. The words were man’s words, but that man’s life had been so framed by God that they were God’s words as well.
