The prologue of John's Gospel presents Jesus Christ as the eternal Word, or Logos, who is both fully divine and truly human. Existing before creation, He is the source of life and light that darkness cannot overpower. This passage refutes teachings that diminish Christ’s deity and affirms the Trinity. The Word became flesh, demonstrating God's presence among humanity and offering grace and truth. This declaration emphasizes the unique nature of Jesus as the ultimate revelation of God and the fulfillment of Old Testament prophecy.
