“The biblical witness cannot be properly appreciated without the illuminating aid of the Spirit. The illumination which he imparts to the believing reader may differ in degree, but does not differ in kind, from the inspiration which moved the original speakers or writers, so that their words became the vehicle of God’s Word. The Spirit’s role is to testify of Christ, and he does so not least in Scripture. The Christocentric understanding of Scripture is not imposed on it from without, and not read into it by allegorization or any other artificial means; it is implicit in the message of Scripture, as that message is made plain by the Spirit. To grasp the witness of Scripture to Christ is the chief end of biblical interpretation.” (F.F. Bruce)
