Whatever notional knowledge men may have of divine truths, as they are doctrinally proposed in the Scripture, yet—if they know them not in their respect unto the person of Christ as the foundation of the counsels of God—if they discern not how they proceed from him, and center in him—they will bring no spiritual, saving light unto their understanding. For all spiritual life and light is in him, and from him alone.
An instance hereof we have in the Jews. They have the Scriptures of the Old Testament, wherein the substance of all divine truth is revealed and expressed; and they are diligent in the study of them; howbeit their minds are not at all illuminated nor irradiated by the truths contained in them, but they live and walk in horrible darkness. And the only reason hereof is, because they know not, because they reject, the relation of them unto Christ—without which they are deprived of all enlightening power.
