It [Scripture] has maintained its authority in the church of Christ to this day. It has prompted all believers–including the greatest minds and noblest spirits–to yield to its authority. What power in the world is comparable to that of Scripture? The testimony of the Holy Spirit is the triumph of the foolishness of the cross over the wisdom of the world, the victory of the thoughts of God over the deliberations of human beings. In this sense the apologetic value of the testimony of the Holy Spirit is second to none. Surely this is the victory that overcomes the world: our faith! (1 John 5:4).
