Biblical veracity and biblical authority are bound up together. Only truth can have final authority to determine belief and behavior, and Scripture cannot have such authority further than it is true. A factually and theologically trustworthy Bible could still impress us as a presentation of religious experience and expertise, but clearly, if we cannot affirm its total truthfulness, we cannot claim that it is all God’s testimony and teaching, given to control our convictions and conduct.
J.I. Packer
