The true knowledge of God—the greatest knowledge humanity can attain—is not innate, universally shared, or discovered through human intellect, but is revealed by God Himself through Scripture, the person of Christ, and the work of the Holy Spirit. This knowledge is essential for eternal life, as Jesus defines it in John 17:3, and is distinct from mere religious zeal or cultural familiarity with God, as seen in Paul's warning to the Corinthians and the reality of idolatry. Though all believers receive an initial revelation at salvation, the Christian life is a lifelong journey of growing in this knowledge, progressing from spiritual infancy to maturity, as emphasized by Paul, Peter, and John. This growth is not for personal gain but for the purpose of the Church being a light in the world, sharing the truth of God's nature and character, and dismantling false ideologies, as God has chosen to reveal Himself through both general revelation in creation and special revelation in Scripture and the incarnate Word.
