“The whole of Scripture stands united by a single and primary author: God.
Rather than a collection of man’s highest thoughts about God, the Christian Scripture is God’s self-communication to humanity about who He is and what He has done to redeem a lost race in Adam.
Inspiration guarantees that the canon’s many stories tell one story; there is a single story to be told because there is a single divine author, who has declared Himself to be its architect and creator.
He is not only the main actor in the drama of redemption but the drama’s scriptwriter.
Presupposed is a striking reality: it is because the story of Scripture has one divine author that His divine authorial intent is embedded throughout Scripture’s storyline.”
