The Divinity of Scripture
it is not the authenticity, nor the canonicity, nor even the inspiration, but the divinity of Scripture, its divine authority, which is the true object of the testimony of the Holy Spirit. He causes believers to submit to Scripture and binds them to it in the same measure and intensity as to the person of Christ himself. He assures them that in life and death and all the crises of life, they can bank on the Word of God and even fearlessly appear with it before the Judge of heaven and earth.
