This essay is born from a deep pastoral and apologetic conviction: that the authority of God's Word isn't just a doctrinal principle, but the vital axis that sustains the church's identity, mission, and unity. As a scholar committed to theological formation and the edification of leaders in my community, I've observed that the most persistent attacks against the evangelical faith don't come from secular skepticism, but from within the church itself—from erroneous interpretations, diluted doctrines, and a growing disconnect between Scripture and life.
