Romans 16:25-27 "Now to Him who is able to establish you according to my gospel and the preaching of Jesus Christ, according to the revelation of the mystery which has been kept secret for long ages past, 26 but now is manifested, and by the Scriptures of the prophets, according to the commandment of the eternal God, has been made known to all the nations, leading to obedience of faith; 27 to the only wise God, through Jesus Christ, be the glory forever. Amen."
God's inerrant Word is the source of the Gospel of salvation spoken of in Romans 16:25. If the Bible were not the inerrant Word of God, we could not trust it to relay accurately the Sovereign goodness of God, His dealings with men like David nor trust that the Gospel woven throughout its pages was of saving value. Christian growth requires an inerrant Bible revealed from the Sovereignly Good God revealed in its pages.
