How do we know that Jesus is the Word of Life?

The claim that Jesus is the Word of Life is rooted in the personal testimony of the apostles as expressed in 1 John 1. John declares that what they have seen and heard concerning Christ is meant to be shared, emphasizing that Jesus is eternal life manifested to humanity. The identity of Jesus as the Word of Life is supported by His actions, teachings, and the fulfillment of prophecies throughout the Scriptures. Moreover, the Bible presents Him not as a mere historical figure but as the living Word, essential for spiritual life and truth.
